Load Balance Routing using Packet Success Rate for Mobile Ad Hoc Networks

Mobile ad hoc networks (MANET) are composed of many mobile nodes equipped with wireless antennas, and one of the critical challenges in the design of MANET is the development of efficient routing protocols. Conventional routing protocols such as dynamic source routing (DSR), often prefer to choose "the shortest path" for data forwarding. However, this mechanism often results in two tendencies, making performance declined. One is so-called "hot spot" and the other is "unstable nodes" selected as intermediate nodes. The proposed load balance routing customarily circumfuse one of these two problems and isolate network layers. Therefore, we combine medium access control (MAC) with routing layer and propose a new load balance routing protocol (LBPSR), using packet success rate (PSR) which we define as the probability of a node can send out a packet successfully. Simulation results show that LBPSR prolong the network lifetime and improve the performance of MANET.
