摘要
当多个智能传感器节点组成网络时,会详细监测物理环境而被广泛使用。但传感器采用电池供电不可替换,为了高效利用电池的能量达到长时间有效监测环境的目的,设计了一种基于异构网络的分区稳定路由协议(PSRP)。该协议根据节点能量把网络分为3个区域,区域0的节点直接跟基站进行通信,区域1和2的节点采用群集机制进行数据传输。群集中簇首的选择主要考虑节点的剩余能量和离基站的距离,较远的簇首采用中继节点转发数据的方式给簇首。最后采用不同的评估方案(例如基站的位置变化和节点能量可变)对PSRP进行评估,结果表明,PSRP协议高效地利用了节点的能量,减少平均能量消耗,增加了网络的稳定期。
When multiple intelligent sensor nodes form a network,it will monitor the physical environment in detail and is widely used.However,the sensor powered by battery is irreplaceable.In order to use the battery energy efficiently and monitor the environment effectively for a long time,a partition stable routing protocol(PSRP)based on heterogeneous network is designed.The protocol divides the network into three areas according to the energy of the nodes.The nodes in area 0 communicate directly with the base station,and the nodes in area 1 and 2 use cluster mechanism for data transmission.The selection of cluster head mainly considers the residual energy of nodes and the distance from the base station.The farther cluster heads use relay nodes to forward data to cluster heads.Finally,different evaluation schemes(such as location change of base station and variable energy of nodes)are used to evaluate PSRP.The results show that the proposed protocol can efficiently utilize the energy of nodes,reduce the average energy consumption and increase the stability period of the network.
