The communication equipment that is configured to serve as the mobile neck person of group will serve as MGL statically, promptly up to the keeper described equipment is reconfigured as and abandons serving as MGL.During the policy engine configuration, MGL will the rule set that is used for mobile group be stored in it can be adaptive policy engine, and described rule can be arranged to for example adapt to the specific environment of mobile group by the keeper, open wholly or in part meeting between for example business meetings of Bao Miing, or colleague or the friend.The maximum number of the horde group node in the interim mobile group is preferably controlled by policy engine, and can be provided with by the keeper.The size accepted of specific interim mobile group also may depend on the load and the capacity of network.Yet usually less than 20 nodes, and more the mobile node of big figure can cause the formation of interim mobile group extra in the CTMNET according to the suitable size of interim mobile group of the present invention.
For the ease of the communication between the MGN in different MG, the one or more MGN among the MG preferably are configured to serve as mobile group by MGL and close MGG, and it is allowed to communicate by letter with the MGG that is arranged in another MG.Alternatively, according to policy engine, MGL can serve as MGG.Controlled interim mobile group management function according to the present invention can make communication equipment serve as horde group node, the mobile neck person of group and mobile group and close.
Interim mobile group (MG) according to controlled temporary mobile network of the present invention (CTMNET) includes limited number horde group node (MGN), be that communication equipment is to enable wireless transceiver apparatus, operation has the network protocol stack based on TCP/IP of new interim mobile group Routing Protocol (Temporary MobileGroup Routing Protocol TMGRP), allow multi-hop communication, and each equipment can be roamed spontaneously simultaneously.According to the different management nodes that are have a static allocation of controlled temporary mobile network of the present invention (CTMNET) with existing mobile and interim ad-hoc network (for example MANET), the i.e. mobile neck person MGL of group as above, and node (MGN) does not allow as in the MANET model automatic and spontaneously add interim mobile group, and be according to the rule in the policy engine that can be adaptive on the contrary, control adding by MGL.New horde group node adds interim mobile group to be controlled according to the predefine in the configured strategy engine in MGL and the policing rule that can be provided with, can be provided with and/or optionally policing rule realize can be adaptive policy engine.Allow between different mobile groups, to have border (border) according to controlled temporary mobile network according to the present invention, and the horde group node in a controlled manner crossing the boundary communicate.
Can comprise predefined rule set by adaptive policy engine, described predefined rule set be default rule with the keeper can be by utilizing network topological information in the network propagation rule and the connective rule of node be communicate by letter (communication group in) in the control of mobile group and management and the MG, communication between the different MG (communicating by letter between group) and switching (transiting) communication and select and the appropriate combination of the rule of setting.
Therefore, interim mobile group according to the present invention comprises one or more horde group nodes (MGN), and a mobile neck person of group (MGL) and one or more alternatively mobile group close (MGG).If suitably configuration, any MGN has the function of serving as MGL or MGG, and MGN, MGL and MGG have unique node name.Expand and implement by increase standard A ODV to AODV message RREQ, RREP, RRER according to an embodiment of the new interim mobile group Routing Protocol (TMGRP) that uses by MG of the present invention.
Fig. 1 illustrates the controlled temporary mobile network 1 that comprises four mobile groups 10,12,14,16 according to of the present invention, and via borderline mobile group pass 104,124a between two mobile groups, b, 142,164 (MGG) communicates the horde group node in the mobile group that separates each other.Each horde group node shown in the figure all comprises communication equipment, the portable personal computer or the PDA that for example have the controlled temporary mobile network function, according to the present invention, the controlled temporary mobile network function can be configured to make that communication equipment can serve as the horde group node.Controlled casual network function does not indicate in the drawings, but is easy to be implemented by those skilled in the art, and this function is not described in detail.
Interim mobile group 10,12,14,16 according to the present invention can realize wireless route in the group, this provides the single-hop between the communication equipment of seeking in the interim mobile group or the possibility of multi-hop, and advertisement service (for example gateway) and control, grant and cancel the possibility of communication equipment about the right of visiting interim mobile group according to the rule in the policy engine among the mobile neck person of group 102,122,142,162 of each interim mobile group.
Two interim mobile groups according to the present invention can realize wireless route between group, this relates to searching out and is arranged in second and moves group, first and move the route of the destination outside the group, and between group wireless route be according to be stored in described first and second move among the MGL of group can be adaptive policy engine in policing rule handle.
Interim mobile group according to the present invention can also realize transit route, and this is not to be arranged at the source node of dialogue or destination node to take place when but go-between group is served as by interim mobile group interim mobile group.During transit route, interim mobile group may want to limit its exposure of network topology and the gateway that selection is used to transfer, and by in the mobile neck person's of group of interim mobile group policy engine, providing clear and definite diversion policy, the particular way that just can control all transfer services by.
Each MG 10,12,14,16 among this figure has MGL 102,122,142,162, the management and control MG each MGN, and MGL with regard to a plurality of membership qualification requests with provide service to the request of communicating by letter to MGN with another MGN.In addition, MGL is also with regard to the membership qualification request, provide service to request of communicating by letter with another MGN and the notice of finding new MG to MGG 104,124,144.
MGL is distributed into statically by for example command option or configuration interface by the keeper and serves as MGL, and each message that receives for MGL, and MGL will consult its policy engine.Can comprise the rule set of describing the definite strategy of asking of application by adaptive policy engine, and according to exemplary embodiment, policy engine comprises a plurality of default rules.In addition, the rule of policy engine can be deleted or be changed, and new rule can be increased so that provide suitable policy engine for the specific environment of mobile group by the keeper.The example of the policing rule of policy engine has MGN whether to be allowed to get in touch another MGN, it is professional whether MGG should receive from the MG that finds recently, which MGN is allowed to add MG, to the access rights of the information resources in the MG, and will use which node in the switching situation.
According to a preferred embodiment of the invention, MGL periodically broadcasts group's announcement, and it serves as the sign of the MGL of interim mobile group to comprise ID of group and indication, and keeps interim mobile group by communicating with the MGN that is designated as the member in the group.The MGN of MG periodically broadcast node announces, and comprises unique name and the ID of group of MGN.In addition, MGL comes supervisory communications by the route that is provided to the MGN that is arranged in other MG via one or several MGG.When MGN became the member of MG, MGL stored the unique name of MGN and IP address together.Thus, MGL can discern the member of MG, and will check which policing rule when the resource in this MG of request.Upgrade if MGL does not receive any membership qualification from MGN in the predefined time interval, then this MGN will be overtime and deleted as the member of MG.
Alternatively, according to one exemplary embodiment of the present invention, MGL is by providing dynamic-configuration for sending IP address, subnet mask and broadcast address to MGN in to the answer (for example RREP) of member's request (for example RREQ) to the MGN that becomes MG member.
According to exemplary embodiment of the present invention, the policy engine of horde group node can dispose by public API (API), and the keeper can carry out registering selected readjustment (call-back) function that is used for the API of particular event during the policy engine configuration to MGL.The keeper can control the policing rule of the MGN that is used to be connected to MG by predefined incident, and can create new events and for new events selection strategy rule with in the policy engine that is stored in MGL.Also be stored in the middle of this MGN self about the policing rule of specific MGN.
Public API generally includes as minor function:
MG_init_policy_engine-starts the registration of incident and readjustment,
MG_register_event-event registration function.
MG_send_membership_request-asks membership qualification.
MG_send_welcome-welcomes MGN to enter this MG.
The MGN that MG_become_member-becomes MG member receives welcome.
MG_drop_membership-leaves MG.
MG_send_message-sends message to MGN.
According to one exemplary embodiment of the present invention, the example of predefined incident that is used for the policy engine of interim mobile group is:
EVENT_NEW_MG_FOUND-finds new MG.
EVENT_LOST_MG-MG disappears, and wherein this MG is the member.
EVENT_MEMBERSHIP_REQUEST-receives the membership qualification request message.
EVENT_WELCOME_RECEIVED-receives welcome message.
EVENT_MESSAGE_RECEIVED-receives message.
Policy engine comprises the rule set that the predefine of indication incident is handled, and policy engine be can by policy engine be provided with or selectable policing rule come adaptive, thereby make specific interim mobile group for example adapt to specific environment with regard to fail safe.The mobile neck person of group comprises the policing rule that is used to manage whole interim mobile group, and the horde group node comprises the policing rule relevant with itself.According to one embodiment of present invention, the example of the predefine of incident processing is:
● when MGN finds new MG, and MGN is not when being the member of any MG, and MGN will ask the membership qualification among this MG.
● the MGN of request membership qualification is accepted as the member with acquiescence.
● when MGN loses and the getting in touch of MG, then this MGN will leave this MG.
● when the MGG among the MG finds the 2nd MG, MGG will report to this MGL of MG.
● when the MGL of a MG when MGG receives the report of indication the 2nd MG, MGL will bear from the 2nd MG and receive data.
Yet, a considerable advantage of the present invention be can be adaptive policy engine, it can make interim mobile group adapt to specific environment.The keeper can select specific policing rule according to the security requirement of for example interim mobile group, and above-mentioned processing to incident only is the example according to event handling of the present invention.
During Fig. 2 interim mobile group that to be diagram managed by MGL 102 when MGN 106 wants to add at the signaling diagram of mobile group example of the signaling between the mobile neck person of group 102 and the horde group node 106 between the neck person discovery period.In step 210, MGN receives the broadcast that comprises the ID of group, and in step 215, MGN comes to MG request membership qualification by send request (RREQ) to MGL.(in fact, MG is to another MGN (wherein broadcast receives from this MGN) transmission request, and if this another MGN be not MGL, then ask to be forwarded to MGL by this MGN).In step 220, MGL consults its policy engine 103 to the connection of MG with regard to MGN.In step 225, policy engine allows MGN to add MG.Finally, in step 230, policy engine sends a reply (RREP) to MGN, thereby allows MGN to add MG, submits new IP address to.
According to preferred embodiment, MGN periodically sends out the membership qualification updating message is still this MG with notice MGL:MGN member to its MGL.Any reception and the node of transmitting this membership qualification updating message will invest this message to its unique name in the mode that piggybacks (piggyback), so that reduce the data traffic in the MG.MGL replys this membership qualification updating message and all MGN on the route of getting back to the MGN that posts a letter will upgrade the startup next time that its timer upgrades for membership qualification.When MGN not when its MGL receives any answer to membership qualification message, MGN will be overtime and be left MG.
Enter the MGN of the scope of another MGN that is arranged in another MG, can apply for the right of getting in touch to its MGL with other MG.MGL will consult its policy engine, and MGN will be appointed to act as MGG (if the policy engine among the MGL allow like this) by MGL, and new MGG will serve as and be used for the border router that all go to data and the routing packets of this MG.
According to exemplary embodiment, when MGN receives mobile group notice message, adjacent group discovery procedure will be performed.MGN will read this message and check whether it comes among the local MG or whether it is from different MG.If this message comes from different MG, then MGN will send group's gateway requests (GGR) message to MGL, be used to indicate the ID of the MG that finds recently.Depend on the rule in the policy engine, MGL can appoint MGN to serve as the single MGG of new MG, in a plurality of MGG of new MG one, and perhaps MGN will be rejected this status as MGG.If route becomes invalid owing to overtime between the group between two MGG in the different interim mobile groups, then each MGG will send routing error between group (Inter-group Routing Error IRE) message to its MGL, thereby make gateway invalid, and MGG loses its gateway status, and turn back to and serve as MGN, move the MGG of group unless it still serves as a certain other.Yet MGN will monitor the MG notice message from other interim mobile groups, and if it receive the MG notice message once more, it can return as MGG.
Conventional MANET uses unformatted addressing (plain addressing), and this is because any node can spontaneously add any MANET at any time.Yet, in interim mobile group according to the present invention, MGN will periodically receive or transmit in the MG or the RREQ of the outside destination of MG, and MGN must be able to determine that route messages or packet go to the MGN among our MG or go to diverse MG.According to one exemplary embodiment of the present invention, this is by to network number, or prefix part, and the inspection of IP address, destination is carried out.When MGN was granted membership qualification in the interim mobile group, IP addresses of nodes for example was reconfigured, succeeded by the replacement of wave point and restarting of Routing Protocol.When source node causes route requests, it will at first be checked to check whether the destination IP addresses of nodes has identical prefix with MG, in this case, the destination node is arranged in identical MG with source node, and route requests constitutes route requests in the group of local destination.If opposite, the prefix of destination node is different with the prefix of local MG, and then route requests constitutes route requests between the group of remote address.Each MGG will use long timer to come this route requests of high-speed cache, and will be forwarded between group in this route requests that contact MGL holds consultation under the situation on the link.Have to the MGL of effective route of all MGN and all MGG, will send IG-RREQ-ALLOWED message now to all MGG that should on link between their group, transmit this route requests.The set of these nodes can use the policy engine of MGL to determine.In order RREQ to be propagated between group on the link, each licensed MGG will transmit the reciprocity MGG of IG-RREQ message to another group, and use the long overtime IG-RREQ that waits for.The equity MGG whether the route requests that inspection enters is gone to local MG, and if it go to local MG, then MGG will get in touch MGL to check whether it should spread into local MG as standard RREQ with this.If IG-RREQ goes to another network, then the MGL that is paid close attention to can be forwarded to every other MGG among the local MG to this request, depend on the policing rule of local MGL.In the routing reply, an IG-RREQ who arrives its destination will be selected as and reply path between the group that is followed between group.The tabulation of (traversed) MGG of traversal will be transported in IG-RREQ, and all IG-RREP subsequently can turn back to the source along this suboptimal path.Because this path is suboptimal (MGL of all traversals of MG resides on the path between the source and destination), upgrades and to be activated so have the local RREQ of the traversal route of more excellent route.
According to another embodiment of the invention, MGL has IP address lease (lease) database, and the unique MGN ID of the overall situation is tied to the table of IP address, node interface is fixedly reconfigured under node temporarily loses the situation of membership for group so that prevent.
Fig. 3 schematically illustrates according to another controlled temporary mobile network 3 of the present invention, comprises three interim mobile groups 31,32,33.The first interim mobile group 31 comprises that horde group node MGN1, the mobile neck person MGL1 of group and mobile group close MGGA.The second interim mobile group 32 comprises that horde group node MGN2, the mobile neck person MGL2 of group and two mobile groups close MGGB and MGGC.The 3rd interim mobile group 33 comprises that horde group node MGN3, the mobile neck person MGL3 of group and mobile group close MGGD.
Fig. 4 be shown in as shown in Figure 3 a MGN (promptly being arranged in the MGN1 of the first interim mobile group 31) and the signaling diagram of the exemplary embodiment of the signaling during the setting up of the route between the 2nd MGN (promptly being arranged in the MGN3 of the 3rd interim mobile group 33).Fig. 4 illustrates the route requests IG-RREQ that sends to MGN3 from MGN1, succeeded by the routing reply IG-RREP that sends it back MGN1 from MGN3.
At first, source node MGN1 broadcasts route requests in step 410, received by MGGA.
In step 415, MGGA is with regard to this route requests contact MGL, and MGL1 turns back to MGGA with IG-RREQ-ALLOWED.
In step 420, MGGA creates IG-RREQ and sends it to second via MGGB and moves group 32.
In step 425, MGGB determines that by checking prefix IG-RREQ goes to this to move group, and IG-RREQ is forwarded to MGL2.
In step 430, MGL2 is forwarded to MGGC with IG-RREQ.
In step 435, MGGC passes to the 3rd via MGGD with IG-RREQ and moves group 33.
In step 440, MGGD recognizes that this IG-RREQ goes to the 3rd to move group 33, and MGGD contact MGL3, and MGL3 consults its policy engine to determine whether this IG-RREQ is allowed in this MG.
In step 445, the MGL response: it is allowed to.
In step 450, MGGD sends to the 3rd interim mobile group 33 with RREQ, and this RREQ is received by destination node M GN3.
Thereafter, in step 455, MGN3 sends to MGL3 with IG-RREP.
In step 460, MGL3 transmits IG-RREP to MGGD.
In step 465, MGGD transmits IG-RREP to MGGC.
In step 470, MGGC transmits IG-RREP to MGL2.
In step 475, MGL2 transmits IG-RREP to MGGB.
