摘要
无线传感器网络中传感节点能量消耗不均衡将导致整个网络过早地失效。文章在LEACH层次路由算法的基础上,提出了自动退避的簇头竞争选择机制、设定阀值的数据融合和基于能量感知的多路径策略,并在网络均衡、能量消耗方面做了优化,极大地提高了传感节点的服务寿命,延长了整个网络的生存周期。
In wireless sensor network, the imbalance of sensor node energy consumption will lead to premature failure of the entire network. Some strategy is put forward based on LEACH hierarchical routing algorithm, such as the cluster head automatic backoff selection mechanism, data fusion with setting threshold and multi path strategy based on energy aware. The network equilibrium and energy consumption are optimized, which greatly improved the service life of the sensor nodes, and prolonged the network life cycle.
