Routing in mobile ad hoc networks - adaptive routing algorithm and MAC layer protocol

摘要

In mobile Ad hoc network, an efficient routing protocol is necessary. In this paper, we firstly survey the usage of node location information in routing protocols. Secondly, we study the algorithm dealing with uni-directional links that result from different transmission power and other differences among the nodes. As a result, an adaptive routing protocol using link life expectancy(LLE) is proposed. The performance of our adaptive routing protocol is evaluated through computer simulation. On the other hand, the performance of a routing protocol is not decided solely by the efficiency of routing algorithm. It is also influenced by Media Access Control (MAC) layer protocols and other factors. Study of MAC layer protocols is presented in the last part of this paper.
