A clustering routing algorithm based on energy consumption balance for underwater sensor networks

针对水下传感器网络能耗不均衡问题,提出一种能耗均衡的多跳非均匀分簇路由算法。算法在水下传感器网络非均匀分簇的基础上,通过改进节点簇头竞选的阈值计算方式,解决了网络后期簇头竞选阈值低导致的网络能耗激增;通过引入多跳路由选择公式,综合考虑节点剩余能量和链路能耗,延长网络生命周期。仿真表明,提出的算法生成簇头数目稳定,能耗较低,并且能有效延长水下传感器网络的生命周期。
Concerning the problem of unbalanced energy consumption in the underwater sensor networks, a Multi-hop Uneven Clustering routing algorithm based on Energy Consumption Balance (MUCECB) is proposed. This algorithm modifies the threshold of selecting cluster head to reduce the sharp increase of the energy consumption, which is led by the reduction of nodes' threshold during the end of the networks' run time. In order to prolong the lifetime of networks, a multi-hop formula of forwarding selected routing is introduced, which considers not only the nodes' rest energy, but also the energy consumption. Simulation results show that, the presented algorithm has stable numbers of cluster heads and low energy consumption and also prolongs the lifetime of the underwater sensor networks.
