Specifically, based on a kind of improvement method for routing based on AODV that above-mentioned steps provide, the method includes the steps:
S101, present node receive the routing update request that Network Central Node is sent, wherein, the routing update request For updating the jump of the optimal routing of the topological number of plies of the present node, the present node to the Network Central Node Several, described present node is marked to the minimum amount of power of the optimal routing of the Network Central Node, the electricity of the present node Remember round.
Network Central Node sets initial routing update required parameter.The Network Central Node setting present node The topological number of plies is 0, the hop count of the optimal routing of the present node to the Network Central Node is 0, the present node arrives The minimum amount of power of the optimal routing of the Network Central Node is that the electricity of present node described in default maximum value is default very big Value.The default maximum of node electricity is more than the electricity maximum value that nodes possess, which is set according to actual conditions.
S102, present node determine whether to receive the routing update request for the first time;If so, perform S103;Such as Fruit is no, performs S104.
Judged when present node is receiving routing update request every time, if the first time for the wheel receives The route requests, if performing S103;If not, perform S104.
S103, the topological number of plies for setting the present node is the first preset value, the setting present node to the net The hop count of the optimal routing of network Centroid is the second preset value, the setting present node to the Network Central Node most The minimum amount of power of excellent routing is third preset value, and empties routing table.
Further, set the topological number of plies of the present node that the present node is set to institute for default maximum value The hop count for stating the optimal routing of Network Central Node is that default maximum value sets the present node to the Network Central Node The minimum amount of power of optimal routing be default minimum.Wherein, the default maximum of the node topology number of plies is more than nodes To the maximum hop count value of Centroid, which is set according to actual conditions;The default maximum of node-routing hop count is more than net All nodes possess the maximum hop count value of routing in network, which is set according to actual conditions;The default minimum of node electricity It is generally set to 0.
S104, a, determine that the topological number of plies in the update request received adds opening up less than the present node after 1 In the case of flutterring the number of plies, the topological number of plies of the present node is updated;
B, judge the route entry with the presence or absence of next-hop for the source node of broadcast update request in the routing table, such as Fruit is no, and the information in being asked according to the routing update adds the route entry;If so, it is taken according to optimal routing minimum amount of power Hop count takes reckling to be updated route entry, and update route record when the maximum, optimal routing minimum amount of power are equal.
Illustratively, if not routing update request is received for the first time, present node is in the update for determining to receive In the case that the topological number of plies in request adds the topological number of plies for being less than the present node after 1, the present node is updated The topological number of plies, the topological number of plies in such as being asked by update is 3, and the current topological number of plies for solving node is 5, due to 3+1<5, so Update the topological number of plies of present node.

Further, the maximum, optimal routing can be taken according to optimal routing minimum amount of power after route entry updates Next-hop node electricity takes the maximum when hop count takes reckling, optimal routing minimum amount of power and equal hop count when minimum amount of power is equal The optimal route record of Policy Updates.
S105 is updated in the topological number of plies of the present node;Current optimal routing exists than the optimal road before update In the case of any below:
(1) the optimal routing minimum amount of power of bigger is provided;
(2) identical optimal routing minimum amount of power is provided, while smaller hop count is provided;
(3) identical optimal routing minimum amount of power, identical hop count are provided, while the next-hop node electricity of bigger is provided Amount;
It is asked with round routing update according to the topological number of plies of the present node and the broadcast of optimal route record, returned simultaneously It returns and repeats the step of present node determines whether to receive the routing update request for the first time.
In practical application, need to judge whether to broadcast update request, as follows:The topological number of plies of present node It is updated, that current optimal routing than the optimal routing before update can provide the optimal routing minimum amount of power of bigger, person is identical Optimal routing minimum amount of power and smaller hop count, identical optimal routing minimum amount of power and hop count and the next-hop node of bigger electricity In the case of measuring any one, same round routing update request is broadcasted, performs S102;Then go off the air.
Further, the method further includes:The situation for the network that the Network Central Node creates is added in new node Under, send route acquisition request;Determine the neighbor node of the new node;The neighbor node sends the optimal of itself and routes to The new node.
Further, can the neighbor node of the new node be determined according to neighbor node lookup algorithm.
During practical wireless transmission, the energy expenditure of transmission data packet meets Eτx(l, d)=l*Eelec+l*εd2, The energy expenditure of received data packet meets Eγx(l, d)=l*Eelec, i.e., it route during the multi-hop transmission of data packet and respectively saves The energy of point received data packet consumption is only and the length of data packet is linearly related, and send the energy of consumption in addition to data packet Length is linearly related outer also related to the physical distance of point-to-point transmission front and rear in routing.The purpose of the emulation experiment is that verification energy is equal Weigh portfolio effect of the routing algorithm to network node electricity, and the simulating scenes built are the logic connection set between node Property, and the actual physics distance and the electric quantity consumption numerical value of reality being not concerned between node, therefore only retain EτxIn (l, d) with away from From unrelated part, i.e. Eτx(l, d)=Eγx(l, d), and by per bit receive energy expenditure on the basis of unit to the total of node Electricity is quantified.
Relationships of the Fig. 2 between data transmission wheel number and balancing energy degree, emulation are laid out for given network node, Comparison is using AODV (Ad hoc On-demand Distance Vector Routing, the on-demand plan range of wireless self-networking Vector Routing Protocol) algorithm and improved AODV algorithms operational effect, it is equal that improved AODV algorithms are also referred to as energy Account method.
The target of the balancing energy routing algorithm of the embodiment of the present invention is to avoid data packet length limitation to network topology depth The limitation of degree, and according to network currently the electricity of each node and neighbor node connectivity structure equalising network electric quantity consumption road By.AODV routing algorithms and the comparing result of balancing energy routing algorithm are as follows.
Scene is made of 1 Network Central Node, 60 common network nodes and 8 sections of obstacles, as shown in Figure 2.Wireless communication It number propagates and to be set as along straightline propagation, propagation distance is 10 unit lengths;The data packet length of transmission is 100bit, and ACK is 50bit, the electricity of each common network node are set as 108Unit energy.Fig. 2 be occur in a network it is entire before failure node Relational graph between the data chartered steamer number of transmission of network and balancing energy degree.
It can be seen from the figure that in this scenario, after using balancing energy algorithm, the wheel number energy of transmitted data on network packet 8 times using AODV algorithms are enough promoted to, the reason is that balancing energy algorithm can avoid those by phase in all optional routings To the route entry of low battery node, pathfinding is carried out according to the sequence of data packet total amount that routing can carry so that all available Routing all fully balancedly utilizes.But the granularity of balancing energy is constantly refined by improving routing update frequency, it can not be notable Promote the effect of balancing energy.
Fig. 3 is data transmission wheel number and balancing energy Degree of Accord Relation figure, is to occur data packet before failure node in a network Relational graph between average transmission energy consumption and balancing energy degree.It can be seen from the figure that in this scenario, using balancing energy After algorithm, data packet average transmission energy consumption improves nearly 50% compared to AODV algorithms, the reason is that network node is route in selection When be not preferential selection shortest path, but the routing of the maximum minimum electricity of preferential selection, this causes the transmission meeting of data packet By more nodes so that the average energy consumption of transmission increases.When raising routing update frequency constantly refines the granularity of balancing energy When, only more frequently switch in a plurality of optional routing, the average energy consumption increase of transmission will not significant changes.
