基于稀疏投影排角分区的无线传感器网络路由协议

Angle Sorting Partition WSN Routing Protocol Based on Sparse Projection

针对无线传感器网络的节点因能量消耗不均导致网络使用寿命缩短的问题,提出一种新的无线传感器网络分区路由协议。该协议首先结合压缩感知理论特征,将冗余数据进行处理,其次通过分区对监控区域进行划分,每个分区中节点生成一条以汇聚节点为终点的路径,使用精英蚁群算法找到节省网络能耗的最短路径。通过与随机游走算法的仿真比较,精英蚁群算法能更直接快速的找到每个网格中的最短路径;与随机分簇投影路由协议相比较,所提的分区路由协议使网络寿命延长,剩余存活节点在网络运行各时期均更为优异,网络性能良好,延长了整个网络使用寿命。

Aiming at the problem that the node of wireless sensor network is shortened due to the uneven energy consumption,this paper proposes a new wireless sensor network partition routing protocol.The protocol firstly combines the characteristics of compressed sensing theory to process redundant data,and then divides the monitoring area by partition.Each node in the partition generates a path with the aggregation node as the end point,and uses the elite ant colony algorithm to find the shortest path of the network energy consumption.Compared with the simulation of random walk algorithm,the elite ant colony algorithm can find the shortest path in each grid more directly and quickly.Compared with the random clustered projection routing protocol,the proposed partition routing protocol extends the network lifetime.The remaining surviving nodes are better in all periods of network operation,and the network performance is good,which extends the life of the entire network.
