| Ad hoc is composed of the temporary multihop autonomous system with the mobileterminal of radio module. The network can work independently or work with Internet and cellwireless network.Route acquisition is a key and difficult problem in Ad hoc networks,becausethe nodes always move frequently,which result in the network topology variety. A networkrouting protocol is the pivotal and core issue for realizing the Ad hoc communication. Aneffective routing protocol is important,which can shield upper layer application from thelower layer adverse factors and can supply a stable,reliable and high efficient communication.In this paper, a new routing algorithm,Ad hoc dynamic routing algorithm-AEMCRP, isproposed to extend the survival time of the node and improve the transmission efficiency.Based on the on Ant colony optimization method and energy energy efficient, this newalgorithm can balance effectively energy in network; improve the route reliability andprolong the network lifetime. Furthermore, another new routing algorithm based on antcolony algorithm AORP is proposed to solve rapidly changing network topology andcongestion of the network data transmission. Addording the energy rate, congestion rate, nodedynamic rate and delay, the routing algorithm choose the routing to transmit data. Afterestablish the routing, routing algorithm update the routing table in nodes by dynamiccollection the information on tramsmission path. Therefore, routing algorithm can improvethe system dynamic allocation of network traffic, reducing network congestion, extend thenetwork lifetime and enhance the adaptive capacity of communication networks.Effectiveness of algorithms have been verified by the simulation in NS2.There is development space in Ad hoc network routing technology, ant-colony, in thisalgorithm, is confined in the network layer. It will become the next research direction thatglobal optimization algorithm of the protocol and each layer of network cooperative work. |
