Abstract


Mobile Ad Hoc Network (MANET) is derived from the earliest to meet the needs of military communications, is composed of many devices with a wireless transceiver mobile terminal consisting of a multi-hop, temporary autonomous system. It usually uses wireless communication, there is no fixed base, strong survivability, mainly used in wiring more difficult environments, such as ad hoc meetings, battlefields and other special occasions. Mobile Ad Hoc Networks multi-hop routing, dynamic network topology, distributed control, independent networking, etc. These special advantages, it is not only in the military field plays an important role, while also civilian areas have good potential applications. As mobile Ad Hoc networks with dynamic network topology, which makes usually used in traditional communication network routing protocols in this environment can not function properly, therefore, the design of routing protocols for mobile Ad Hoc networks of the important issues. AODV routing protocol is designed for mobile Ad Hoc network design typical on-demand routing protocols, and probably in the future mobile Ad Hoc network applications occupy an important position. This paper describes in detail the characteristics of mobile Ad Hoc networks, and then AODV routing protocol in-depth analysis, and briefly describes the AODV routing protocol with the relevant existing research results. In this paper, mobile Ad Hoc network node energy consumption is not balanced and AODV routing protocol deficiencies, proposed an improved scheme - P AODV routing protocol. P_AODV routing protocol is based on AODV routing protocol on how to make full use of the limited node energy research. The algorithm proposed in the routing control information, each node in the network to increase the residual energy state judgment parameter, along the main route in the data packet transmission process, if the remaining energy shortage is detected nodes, in which upstream build bypass, and will pass the node network load according to a certain probability assignment to the main route and bypass the on so as to improve network performance, prolong the network lifetime purposes. By analyzing the network simulator (NS-2) Simulation results verify the improved AODV routing protocol in the data packet transmission success rate, end to end average delay, routing overhead, network lifetime and so have improved significantly. In this paper, Red hat Enterprise Linux 4.0 operating system, relying on NS-2 simulation tool to build mobile Ad Hoc network simulation platform, through simulation environment using the same settings, simulation comparison AODV routing protocol and network performance P_AODV routing protocols to verify the P AODV routing protocol is feasible.
