摘要
在无线传感反应网络通过引入具有丰富资源、甚至可以移动的反应节点,极大地增强了现有的无线传感器网络的功能和应用范围。针对距离反应节点越近传感节点能量消耗越快的问题,研究了基于容量约束的最大跳数最小化的问题,并在此基础上提出了一种全局近似算法。仿真实验表明,该算法能通过设置节点的容量约束,限制节点每轮转发某个事件的最大报文数,以降低单个节点的最大能耗,达到延长网络生存时间的目的。
Wireless sensor and actor networks greatly enhances the existing wireless sensor networks＇ function and application field by introducing powerful and even mobile actors. In this paper, the min-max hops problem based on the bounded capacity is considered in light of the phenomenon that sensors consume energy quickly when near to actors, and then a global approximate algorithm is given. The simulation experiment result indicates that the algorithm can limit the maximum number of the retransmitting packets for some event in every turn and reduce the maximal energy consumption of single sensor by setting the capacity constraint of the sensors for prolonging the network lifetime.
