基于距离成本能量有效的传感器网络路由协议

Distance-driven Energy Efficient Routing in Sensor Networks

负载均衡和路径恢复给数据分发的大规模传感器网络带来了挑战。这些问题可以通过多路径和故障恢复路由部分得到解决。不幸的是现存的协议还不能满足大规模传感器网络的需求。现提出一种新的路由算法,DCEP(Distance Cost Ener-gy Efficient Protocal)。它通过计算节点间距离来建立传输路径。此协议不需要节点的位置信息。仿真表明此协议与DD(Di-rected Diffusion)、GPSR(Greedy Perimeter Stateless Routing)协议相比具有优异的表现。

Load-balance and path recovery bring new challenges to data dissemination in large sensor networks. These issues can be partially addressed by Multi-Path or Path-Recovery routing. Unfortunately, these protocols are unable to meet the requirement of large-scale sensor networks. A new routing method is proposed, called DCEP（ Distance Cost Energy Efficient Protocal）, which build transmission path by calculating the distance between nodes. This protocol does not need nodes with location information. Simulation shows the protocol have an excellent performance performance compared with DD（ Directed Diffusion） and GPSR（ Greedy Perimeter Stateless Routing）.
