碩士 / 大同大學 / 通訊工程研究所 / 103 / Mobile ad hoc networks (MANETs) have recently been researched and deployed. They are composed of a number of nodes, each acting as a router and operating in an ad hoc fashion. Nodes in a MANET have limited energy, hence, the routing protocol should be energy efficient to extend the lifetime of the network. The topology of a MANET is constantly changing due to the mobility of the nodes. A proactive routing protocol which broadcasts control packet more frequently can provide more accurate routing table. The fisheye state routing (FSR) protocol was proposed to reduce the control traffic. In order to increase the energy efficiency, we improve FSR by considering the residual energy of nodes as a factor of computing routing table. The residual energy of each node is classified into four levels and the energy level is then inserted into the control packet to be distributed. To decide the energy efficient routes, we compare two formulas to include the energy levels. One is additive; the other is multiplicative. Simulation results show both modified FSRs outperform the original FSR. The energy-efficient FSR saved up to 67% energy consumption and has more than 90% of packet deliver rate. Throughput of the energy-efficient FSR is 1.56 times higher while end-to-end delay is lowered to 25% of that of the original FSR.
