The Study On Self-organizing Network Routing Algorithm On OPNET

Mobile Ad Hoc network is a wireless, mobile, self-organizing network. It has no central control node. The mobile node via multi- hop wireless links communicating with each other. Since there is no central control node, each node in the network must have the forwarding function of the router. And sometimes in order to meet the actual demand, we need to achieve some unique features. Ordinary mobile Ad Hoc network routing protocols cannot meet the current demand, so mobile Ad Hoc network routing protocols for specific applications is a hot issue in network research.Mobile Ad Hoc network is used in many fields, especially in the military field applications, particularly extensive. In the specific military applications, no center of the Mobile ad-hoc network but also to the specific application requirements brought some difficult and sometimes need to set a centra l control function node has in the network, and the node can be replaced, so the design effective way to become the key to solving the problem.Based on the existing Ad Hoc network routing protocols, routing algorithms and routing protocol design rules in-depth analysis on the design of a central node function and the central node can replace intelligent routing algorithms, based on the underlying TDMA simulation of communication routing protocol. The routing algorithm and the address of the terminal node in the network state based on the network address of a node according to the size of its central node table constructed order to improve the efficiency of replacement of the central node, the network node in the network will be constructed at the same time information in accordance with the order of the node address added to the table, then periodically update the selection list after the first network node as the central node of the network can be. After the failure of the network center, and then click F ind central node table to elect an alternative node. Finally, we use OPNET simulation platform validated simulation, through the design of routing protocols after the results of the analysis found that the routing protoco l operation can work in a self-organized mobile network environment, to achieve a central node and the central node replace function, to meet the specific requirements for military purposes.
