Abstract: 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.
