摘要
针对无线传感器网络(WSN)的多跳分簇协议中,Sink节点附近的簇头能量消耗过快,簇头分布不够均匀,多跳链路不够高效等关键问题,提出了基于控制的低能耗多跳分簇路由协议。通过控制成簇数量与大小、多跳链路能耗、轮数与每一轮中的数据传输量来解决以上问题。仿真结果表明:所提协议与低功耗自适应分簇(LEACH)协议和基于非均匀分簇的无线传感器网络路由协议(EEUC)相比,网络稳定期分别延长了138%和13%,网络生命期分别延长了13%和8%,因此能够有效地降低网络能耗,均衡网络负载,延长网络生存时间。
In multi-hop routing protocol of Wireless Sensor Network （WSN）, the cluster heads near the Sink node consumes faster than other cluster heads, the cluster heads are uneven distributed, and multi-hop links are not effective. To solved these problems, a low energy consumption multi-hop routing protocol based on control was proposed. The clusters＇ number and size, the multi-hop links＇ energy consumption, the number of rounds and the quantity of the data transmission were controlled. The simulation results show that this routing protocol prolongs the network＇s stable period time by 138% and 13%, and it also prolongs the network＇s lifetime by 13% and 8% in comparison with the Low Energy Adaptive Clustering Hierarch （LEACH） and uneven cluster-based routing protocol for wireless sensor networks （ EEUC）. Therefore, the proposed protocol can reduce the energy consumption of the network, balances network load, and prolongs the survival time of the network efficiently.
