摘要
在无线传感器网络的簇间路由协议中,簇头单跳或者多跳通信,都会导致簇头能量消耗不均衡。为了均衡能量消耗,新的协议在LEACH-C协议基础上,引入一个有关距离的阈值,若簇头距离基站的距离小于该阈值,则进行单跳通信;若簇头距离基站的距离大于该阈值,则进行多跳通信,同时提出一种保证时延的簇间多跳路由协议(Distance and Delay Based Cluster Routing Protocol)DDCR协议。经过仿真实验,验证了该方法的可实现性,有效地降低了簇头节点的能量消耗,均衡了网络负载。
In the inter-cluster routing protocol of wireless sensor networks, cluster head single hop or multiple hops communica- tion, cluster energy consumption will lead to imbalance. In order to balance the energy consumption, the new protocol based on LEACH-C, introduces a threshold of distance. If the cluster head distance from the base station is less than the threshold value, the single hop communication should be conducted. If the cluster head distance from the base station is greater than the thresh- old, the multi-hop communication should be conducted, also a guaranteed delay new multi-hop routing algorithm is proposed. This protocol effectively reduces the cluster head node energy consumption, balances network load.
