Abstract: Mobile Ad hoc network (MANET) is a multi-hop non-centric self-organizing wireless network, in which there are two important route optimize metrics-- load and energy. It is hard to fully describe the two metrics by using numerical value because of their dynamical varieties during routing process. With the idea of fuzzy sets and fuzzy logic, this paper proposes a fuzzy logic and state aware routing protocol (FLSAR), and presents an integrated route metric combining load and energy, which enables them to be balanced in the whole network. The simulation by NS2 illustrates that the throughput and lifetime of network are effectively improved.

摘要： 移动Ad hoc网络(MANET) 是一种多跳无中心自组无线网络，其中负载和能量是两个重要的路由优化指标。由于在路由过程中它们会动态变化，所以很难用具体数值去完整描述。为此，本文引入模糊集与模糊逻辑的思想，提出了一种基于模糊逻辑与状态感知的路由协议(FLSAR)，给出结合负载和能量的综合路由指标，使整个网络中负载和能量能更均匀地分布。NS2仿真结果表明，本协议能较好地提高吞吐量和延长网络生存时间。
