摘要

摘要: 基于离散空间最优搜索理论中的基于博弈理论的协作策略模型,通过综合考虑无线传感器网络中节点转发数据所付出的代价和利益、节点能耗及相邻节点过去的行为,提出了一种自适应能耗均衡网络协作模型,并给出了相应的数学最优化模型及求解算法。优化的目标是均衡网络能耗和吞吐量,进而最大化网络寿命。模型通过能量因子和转发数据包数量来调节节点行为,使传感器网络的整体能耗趋向均衡。一个数值例子说明,该路由选择策略及求解算法是可行且有效的。

Abstract: Base on collaboration model of optimal search theory in discrete spaces, an energy balancing collaboration model and its solution algorithm in wireless sensor networks are proposed in this paper by taking all the following factors into consideration: the costs and benefits of node to forward data, energy consumption, and the behavior of adjacent nodes in the past. The objective of the algorithm to balance the energy consumption and maximize the network lifetime. An energy factor and number of packets transmitted are presented to make the energy consumption of the network tend to equilibrium and maximize the network lifetime. A numerical example illustrates the validation of the proposed collaboration model and policy.
