无线传感器网络中,聚簇机制对中间数据聚合节点的能耗节省具有显著作用。本文在无线传感器网络中使用基于多层聚簇的能耗优化模型来最小化数据收集过程中的能量消耗。文中对该多层聚簇传感器网络提出一种能耗模型,该模型的能耗不仅包括数据传输过程中的能耗,同时也涵盖了聚簇头结点轮换的能耗。基于该新模型,对一个给定的传感器网络,我们可以使用文中给出的数值方法计算出最优聚簇层数,并通过本文提出的分布式多层聚簇算法来构造一个节能多层聚簇传感器网络。实验结果表明新的能耗模型的计算结果和实验结果趋势保持一致,同时多层聚簇传感器网络的数据聚合能耗确实在使用能耗模型计算的最优层数时,能量消耗达到最小。

Abstract: In wireless sensor networks, a clustering scheme is helpful in reducing the energy consumption by aggregating data at intermediate sensors. This paper discusses the important issue of energy optimization in hierarchically-clustered wireless sensor networks to minimize the total energy consumption required to collect data. We propose a comprehensive energy consumption model for multi-tier clustered sensor networks, in which all the energy consumptions not only in the phase of data transmissions but also in the phase of cluster head rotations are taken into account. By using this new model, we are able to obtain the solutions of optimal tier number and the resulted optimal clustering scheme on how to group all the sensors into tiers by the suggested numerical method. This then enables us to propose an energy-efficiency optimized distributed multi-tier clustering algorithm for wireless sensor networks. This algorithm is theoretically analyzed in terms of time complexity. Simulation results are provided to show that, the theoretically calculated energy consumption by the new model matches very well with the simulation results, and the energy consumption is indeed minimized at the optimal number of tiers in the multi-tier clustered wireless sensor networks.
