摘要:
LEACH协议是无线传感器网络中层次型路由协议的典型代表,网络中节点自动成簇,簇内成员通过簇首与基站通信,网络定时选举簇首以均衡节点能量。但节点在空间上分布不均以及在每轮稳定阶段担当簇首的节点能耗不均都会使得网络平均性能下降。提出了基于LEACH的线性预测能量消耗均衡路由协议,能够通过预测下一轮的能量消耗速率来动态调整下一轮的簇首切换的时长。仿真结果显示该协议在能量消耗、实际单位比特所耗能量和网络生命周期等方面性能更好,能均衡网络能量消耗,延长网络生命周期
Abstract:
LEACH protocol is a classical hierarchy route protocol in wireless sensor networks.It elects some nodes to communicate with base-station,and balances the consumption of node energy by selecting cluster＇s head at certain times.But the nodes are random in area,and the energy consumption isn＇t well-distributed in every steady-state phase,so that the average performance of networks declines.Gives a linear predictive of average energy dissipated,which predicts the next dissipated speed of average energy,and dynamically adjust the interval of changing cluster＇s head.Take the energy consumption,average energy consumption per bit and networks＇ lifecycle as standard to measure the networks＇ performance,and the result shows that our improved,compared with LEACH protocol,is better than LEACH in balancing the networks＇ energy consumption and prolonging its lifecycle
