Ad Hoc网络基于能量消耗的动态源路由协议

为了节省路由能耗，增加网络中节点生存时间，提出一种基于能量消耗的Ad Hoc网络动态源路由协议（ECDSR）。该协议以路由剩余能量、路由能耗预测、路由能量延时3个参数作为路径能量评价的参数。其中剩余能量参数反映了节点当前的剩余能量状态，能耗预测参数反映了节点能量的变化情况，能量延时参数能够保护低能量节点，屏蔽能量状况差的路由路径。仿真结果表明该协议相对于动态源路由（DSR）可以在网络时延和协议开销增加不明显的前提下，提高网络的生存时间等网络性能。

Routing protocol based on energy consumption in Ad Hoc networks

To save the energy consumption of routing paths and prolong the lifetime of network nodes, the authors proposed a new Dynamic Source Routing Protocol of Ad Hoc network based on Energy Consumption (ECDSR). In ECDSR, it imported three energy evaluation parameters (residual energy, consumption prediction, energy delay) to evaluate the energy status of routing paths. Residual energy reflects the current state of node's residual energy, Consumption prediction reflects the changes of node's energy, and energy delay can protect the low energy nodes, and avoid the routing paths with poor energy state. The simulation results show that compared with DSR, ECDSR, the proposed protocol works better in prolonging the network lifetime and improving the network performance without significantly increasing the network overhead and delay.
