基于能量感知的传感网能量中性分簇路由协议

针对能量获取异构的无线传感器网络节点能量利用效率过低和网络无法保证持久运行问题，提出一种基于能量感知的能量中性分簇路由协议，该协议针对太阳能环境下节点获取能量异构的场景，将改进的天气条件移动加权平均算法引入能量收集预测过程，根据获取能量预测构建能量中性约束，在此约束下构建动态簇头集群机制和自适应时隙分配策略，保证了整个网络在能量获取下的持久运行，通过凸优化得到最优的网络分簇数量，最大化了网络数据吞吐量。通过模糊逻辑选择簇头节点，综合节点剩余能量，获取能量预测和节点相对位置等多种因素，提高了簇头选举的合理性。通过仿真分析，该协议能够保持能量获取下网络持久运行，在网络吞吐量和降低簇失败次数方面的性能具有明显优势。

Energy-awaring based sensor network energy neutral clustering routing protocol

Aiming at the problem that energy utilization efficiency of wireless sensor network nodes with heterogeneous energy acquisition is too low and the network cannot guarantee long-term operation, an energy-aware energy neutral clustering routing protocol is proposed, the protocol is applied to the scenario of heterogeneous node acquisition capability in solar energy environment. The improved weather condition moving weighted average algorithm is introduced into the energy harvesting prediction process. The energy neutral constraint is constructed according to the acquired energy prediction. Under this constraint, constructing a dynamic cluster head set mechanism and an adaptive time slot allocation strategy ensures the long-term operation of the entire network under energy acquisition.Secondly, the optimal network clustering number is obtained by convex optimization, and the network data throughput is maximized. Finally, the cluster head node is selected by fuzzy logic, comprehensive factors such as residual energy,energy prediction and relative position of nodes are obtained,which improves the rationality of cluster head election.Through simulation analysis,the protocol of this paper can maintain the long-term operation of the network under energy acquisition. Performance in terms of network throughput and cluster failures reduction has significant advantages.
