传感器网络中一种分布式数据汇聚层次路由算法

由于传感器网络具有能量约束,低速率冗余数据和多对一传输等特点,传统的端到端集中式路由算法一般不适合传感器网络.提出了一种分布式数据汇聚层次路由算法,该算法利用能量核的思想汇聚数据和减少传输到目的节点的信息.模拟结果表明:比较传统的端到端集中式路由算法,该算法可以显著减少能量消耗;与一般的数据汇聚算法相比,该算法在保证能量消耗少的条件下,具有复杂度低和可扩展性好的特点.

A Distributed Data-Centric Clustering Hierarchical Routing Algorithm for Sensor Networks

Sensor networks have severe energy constraints,redundant low-rate data,and many-to-one flows.The traditional end-to-end routing algorithms are usually central and are not adapted for sensor networks.A distributed data-centric clustering hierarchical algorithm is proposed,which uses the energy-core concept to perform aggregation of data in the network and to reduce the amount of information that must be transmitted to the sink.Simulations show that,compared with the traditional end-to-end algorithm,this algorithm can significantly reduce energy dissipation.Compared with the data-centric algorithm without clustering,the data-centric clustering hierarchical algorithm offers better performance gains in complexity and scalability,while still being energy efficient.
