Detailed description of the invention

Below in conjunction with accompanying drawing, technical scheme is described in further detail:

The present invention, based on the feature of information age, gives the mode of operation that a kind of wireless Ad Hoc acts on behalf of incidentally SOAP (Self-organizedAgentPiggyback) network, the definition of various transmission message and specific works method。

Rate is held per capita with regard to current wireless mobile phone terminal, complete to reach the autonomous operation mode of SOAP network, SOAP agency is owing to being have relatively large storage capacity space, and continuous electricity can be charged at any time, therefore changing the life span of WSN node and the problem that memory capacity is limited, range of application is greatly promoted。The transmission of " point-to-point " that be not built upon on Reliability Channel due to soap message, it is belonging to " incidentally " function, therefore for ensureing the maximum of probability of transmission, take the form of many copies, be defined at incidentally message PM (PiggybackMessage)；Considering the SOAP network information security, also define safe encryption mode and accredited credit CA (CreditAuthorized) pattern to node, each SOAP agency establishes blacklist pattern, for rejecting the SOAP agency being likely to be harmful to。

Therefore the present invention completes SOAP network delivery multi-service application from macroscopic perspective, including clear data binary file, and content-based text, voice, image and multimedia file。Certainly, the communication under disaster pattern mainly it is applied in due to SOAP network, the transmission of content of multimedia is intended only as the integrity of SOAP procotol to be existed, in concrete practical application, it is main for mainly still transmitting the safe and reliable and maximum of probability transmission compressed file of efficient message, text, voice and picture material。This itself is also the practical significance that SOAP network is born and exists。

The invention belongs to mobile Ad hoc network and social networks, by when making full use of mobile base station and satellite inefficacy, when legacy network enters collapse, utilize the short-distance wireless function that wireless terminal carries, it is automatically composed SOAP network, SOAP act on behalf of quantity intensive in efficient communication, the time delay tolerable communication when SOAP agency is sparse, maximum of probability incidentally transmits reliable news to the greatest extent, split by the information source based on content of different nature, the next SOAP agency of each SOAP agent selection credit forwards, thus completing the transmission of the soap message of many copies, the final recovery that by SOAP receiving terminal, all soap messages received are carried out maximum of probability in deadline DT。

As it is shown in figure 1, be that the general function of the SOAP network delivery soap message of the present invention realizes process, specific as follows:

Step A1, SOAP transmitting terminal processing procedure:

A1.1 needs the wireless terminal obtaining SOAP service to need to carry out installing and registering；

A1.2SOAP business is started by SOAP user, and the content to send is divided into multiple content blocks (CB, ContentBlock), when carrying out piecemeal, it is possible to adopt content-based SOAP source transmitting terminal processing procedure (shown in Fig. 8) hereinafter；

Step A2, current SOAP user do not stop search wireless signal around, and send docking request,

Step A2.1 wireless signal docking after two SOAP users exchange management message MM, exchange route messages RM (RoutingMessage) mutual after,

Step A2.2 meets forwarding condition as the SOAP determining docking acts on behalf of, then CB copy consigns to this SOAP agency, is incremented by 1 with stylish copy mark；

Step A3, all of down hop SOAP agency is then according to as above rule, the sensing according to the FAL/FALS of oneself, and this copy CB arrives purpose SOAP receiving terminal through multiple SOAP agency the most at last；

Step A4, SOAP transmitting terminal multiple copy CB also can pass through its run into other SOAP agency incidentally forward, until copy mark arrive threshold value (being defaulted as 6), if it find that already more than DT on behalf of soap message incidentally, then abandon；If it find that be transmitted across on behalf of soap message incidentally, also abandon；

Step A5, SOAP receiving terminal are within DT deadline (DueTime), and the CB of like-identified copy verification passed through is normalized by big probability, and the CB that can collect is merged into the source file of a maximum of probability integrity；If SOAP bag is to transmit by content model, then pay to final upper-layer user by pattern corresponding in soap message。

As in figure 2 it is shown, be the SOAP network hierarchy of the present invention, specifically include:

B1, physical layer (PhysicalLayer), the bluetooth possessed by wireless terminal self at present, Wifi support, are likely to future comprise specific wireless room from technology, such as Zigbee；

B2, radio link layer (WirelessLinkLayer), the current comparative maturity of Bluetooth protocol, the direct-connected current standard of WLAN of Wifi technology is but without international uniform, and ZigBee technology needs individually definition；

B3, soap message layer, be similar to the Internet of TCP/IP, encapsulates concrete message, including management message MM, route messages RM, and the soap message etc. of the particular content incidentally forwarded；

B4, application layer, reliable binary file, text, voice, image or multimedia video etc. are provided to targeted customer, video it is not recommended that transmit under so emergent SOAP network environment, and the reliable message of the safety of main transmission secret, data volume is it is not recommended that big。

As it is shown on figure 3, the SOAP agency of the present invention opens SOAP service process, particularly as follows:

Step C1, SOAP agency arranges radio configuration pattern, opens the contiguous SOAP subscriber signal of search and initiates docking function；

Step C2, as select 1, bluetooth mode, then put the machine blue-teeth equipment management class LocalDevice in open mode:

Bluetooth signal near step C2.1 search, utilizes DiscoveryAgent class and DiscoveryListener interface to provide the discovery service of needs；

Step C2.2 query search to bluetooth ID whether matched, a list existed is obtained by DiscoveryAgent.retrieveDevices () method, if in list, it was shown that having at least possibility the other side is also SOAP proxy user；

Step C2.3 sends connection request, and the main the other side of prompting allows to set up bluetooth and connects, if the Bluetooth signal of the other side is also opened by SOAP agency, then can agree to connection request；

Step C2.4 sets up bluetooth opposite joining relation:

Step C3, as selected 2, Wifi pattern, then put unlatching the machine Wifi, when SystemServer starts, the example of a ConnectivityService can be generated, create WifiStateTracker and WifiService object, being used for starting Wifi management service WifiStateTracker and can create WifiMonitor for receiving the event from bottom, WifiService and WifiMonitor is the core of whole module。

Step C3.1 brings into operation thread WifiMonitor, Wifi signal near search；

Step C3.2 sends the direct-connected request of Wifi, and the MonitorThread in WifiMonitor can be executed to process and connect scanning result event；

Step C3.3 sets up Wifi opposite joining relation。

Substantially ibid, call function has difference to Zigbee mode process。

As shown in Figure 4, it is the message interaction process between two SOAP agencies of the present invention, particularly as follows:

Step D1, two SOAP agencies are after setting up radio physical signal link and connecting, it is necessary to again send SOAP and shake hands successfully, confirm that SOAP each other acts on behalf of character；

Step D2, need transmission task SOAP agency first find the other side in FAL or FALS, as, then initiate MM message session, inquiry the need of incidentally forwarding, as find: (1) time-out；(2) copy is forwarded over；(3) opposite end capacity is low；(4) safe mode not couplings etc., then abandon soap message and forward；No matter result how, after conversation end and all will update the node capacity collection that route chain FAL or FALS and correspondence within the specific period time；

Mutual route messages RM (RouteMessage) message between step D3, SOAP agency, if the other side SOAP agency is in local FAL, then updates the FALS chain that this node is corresponding, and both sides exchange renewal each other；

Step D4, there is the SOAP agency of incidentally task according to the character of oneself SOAP bag and requirement, if it is determined that the SOAP agency passing through current docking is incidentally forwarded, then send content incidentally message PM (PiggybackMessage), after conversation end and all will update the node capacity collection that route chain FAL or FALS and correspondence within the specific period time。

G3, credit pattern, based on six topology degree of social networks, set maximum credit node L (L≤10), and the SOAP as currently docked acts on behalf of in credit node L, then forward；Otherwise, then abandon；

G4, urgent pattern, when step G2, set urgent pattern, makes the SOAP application acted on behalf of can adjust path in time, accelerates to join with target SOAP agency。

Route switching process between the SOAP agency of the present invention, mainly includes main chain FAL, from chain FALS, blacklist etc., specifically comprises the following steps that

Send MM message after step H1, two SOAP proxy interfaces, carry out capability negotiation, update the main chain FAL of oneself respectively；

Step H2, take without other tasks, then intercourse the main chain of oneself, and the main chain of the other side is updated oneself from chain FALS；

If step H3 one side sends blacklist request, then both sides update the blacklist of oneself, and stamp blacklist labelling in the capability set of the node of corresponding FAL。

Present invention additionally comprises SOAP agent node chained list FAL and automatically update process, mainly the auto-sequencing of main chain FAL, as shown in Figure 10 it (a) and (b), specific as follows:

Step G1, the update cycle defining the specific FAL of automatically updating are T (T=24 hour), and within a update cycle, certain SOAP agency adds up all SOAP agency of institute's intersection in this time period and adds up to N,

G1.1 defines frequent factor F_iFor acting on behalf of the number of times of complete interactive communication with i-th SOAP；

G1.2 defines Persistence Factor M (i),

Represent the total duration with i-th full communication, then

$M\left(i\right)=(1+\mathrm{\α}\frac{ST\left(i\right)}{\underset{j=1}{\overset{N}{\Σ}}ST\left(j\right)}),i\∈\[1,N\]$

G1.3 defines intimate factor H (i), i ∈ [1, N]

$H\left(i\right)=\left(1+\mathrm{\β}\frac{Max\left\{\left(i,k\right)\right\}}{\underset{j=1}{\overset{N}{\mathrm{\Σ}}}Max\left\{T\left(i,j\right)\right\}}\right),k\∈\[1,Fi\],\mathrm{\α}+\mathrm{\β}=1.$

8. a kind of wireless Ad Hoc according to claim 4 acts on behalf of incidentally network soap message transmission method, it is characterized in that, mutual route messages RM message between SOAP agency in step 302, route messages RM message includes main chain FAL, from chain FALS, blacklist, concretely comprises the following steps:

After step (1), two SOAP proxy interfaces, take without other tasks, then intercourse the main chain FAL of oneself, and with the main chain FAL of the other side update oneself from chain FALS；

Step (2) is if a side sends blacklist request, then both sides update the blacklist of oneself, and stamp blacklist labelling in the capability set of the node of corresponding main chain FAL。

9. a kind of wireless Ad Hoc according to claim 8 acts on behalf of incidentally network soap message transmission method, it is characterised in that updates route chain and refers to the auto-sequencing of main chain FAL, particularly as follows:

Step a, the update cycle defining the specific FAL of automatically updating are T, and within a update cycle, certain SOAP agency adds up all SOAP agency of institute's intersection in this time period and adds up to N, defines frequent factor F_iFor acting on behalf of the number of times of complete interactive communication with i-th SOAP；Definition Persistence Factor M (i), defines intimate factor H (i), i ∈ [1, N]；

Step b, calculate current i-th SOAP agency utmost good faith Index A TI:

ATI (i)=F_i*M(i)*H(i)

Step c, do reference with the credit index E TI in P the cycle of past, then obtain continuous sequence:

ETI (i, j) }, j ∈ [n-PT, n-T],

Wherein n was the n-th update cycle, and T is the acquiescence update cycle；

Thus, being calculated as of current credit index:

$ETI\left(i\right)=1/P\left\{\left(\underset{j=1}{\overset{P-1}{\Σ}}ETI\right(i,j)\right)+ATI\left(i\right)\},$

ETI (i) will be generated and leave node capacity concentration, i.e. ETI (i, 0)=ETI (i) in；And as the part that the ETI in next P cycle calculates。

Step d, to the main chain FAL updating node capacity collection, resequence according to the value of current ETI is descending, namely generate main chain FAL credit FAL and up to FAL。

10. a kind of wireless Ad Hoc according to claim 8 acts on behalf of incidentally network soap message transmission method, it is characterised in that main chain FAL includes node statement and chained list FAL is acted on behalf of in forwarding；Wherein:

Node is stated by ID, node capacity collection, next node pointer representation；

Forwarding is acted on behalf of chained list FAL and is from the close-by examples to those far off formed chained list by intimate degree, and acquiescence effectively forwards chained list length to be N, 6≤N≤10。
