摘要:

在均匀分簇的基础上,分析了多簇群情况下单跳和多跳模型能量的有效性,给出了两种情况下计算最优簇首数目的算法。考虑到单一的路由模式会引起网络能耗不均衡,提出并改进了多簇群情况下利用时间分量的单跳和多跳相结合的混合模型。仿真结果表明,基于时间分量的混合通信模式在能量有效性和能耗均衡分配方面均优于单跳、多跳模式。

Abstract:

Based on the even clustering protocol,the energy efficiencies of the single-hop and multi-hop communicationmodels are analyzed in the presence of multiple local clusters,and the corresponding algorithms to calculatethe optimal cluster head number are presented. Moreover,by taking into consideration the nonuniform energy consumptioncaused by a single routing mode,a hybrid communication model is established,which combines the single-hop and the multi-hop modes with a certain time-component in the presence of multiple local clusters. Simulatedresults indicate that the proposed hybrid communication mode with time-component outperforms the single-hopand the multi-hop ones in terms of energy efficiency and energy consumption uniformity.
