摘要
在分析LEACH协议簇头分布不均匀特性的基础上改进处理得到HEED协议,对群内传感器节点的剩余能量和传感器节点在群内的通信代价进行综合考虑分析,提出了一种以HEED协议为基础,同时把多输入多输出引入到簇间的数据传输中,建立在簇间协作节点的选择机制.与传统LEACH和HEED算法进行比较,此路由协议算法可以大幅度的改善网络均衡性,提高能量有效性以及延长传感器网络生命周期.
The improved HEED protocol was obtained by analyzing the uneven distribution characteristics of cluster heads of LEACH protocol. The sensor network node of the cluster and residual energy of nodes in the group of comprehension, which analysis and comparison on communication costs, put forward a selection mechanism in the cluster nodes based on the agreement with HEED, took the multi - input and multi - output into data transmission be- tween clusters. Compared LEACH and HEED with traditional algorithms, this method could improve network balance significantly, energy effectiveness and could also extend the life cycle of sensor networks.
