【摘要】 在无线传感器网络中能耗是必须考虑的一个重要因素,由于无法对节点的能量进行再输送,应尽可能地减少系统能量的开销、延长整个网络的生存时间。文中对无线传感器网络的能耗与最优簇首节点数量之间的关系进行了理论分析与研究,得出的结论对无线传感器网络规划、设计有一定的指导作用。更多还原

【Abstract】 Energy consumption is a vital factor of wireless sensor networks. Due to the fact that it may be inconvenient or impossible to recharge node batteries, these networks should try by every possible means to reduce energy consumption and prolong the lifetime of the system. This paper conducts theoretical analysis and studies on the relationship of between energy consumption and the optimal number of cluster heads. It provides the useful results that can guide the plan and design of wireless sensor networks.更多还原
