【摘要】 在无线传感器网络中,由于其自身特点的限制,如何使网络中节点的能量损耗最小化成为该网络实用化的主要障碍。文章在综合考虑了路由跳数、节点位置、节点能耗对路由选择影响的基础上,提出了一种融合MAC层和路由层的跨层设计方案。仿真结果表明,该文所提出的算法能显著减少网络能耗,提高能源有效性。更多还原

【Abstract】 In wireless sensor network,since its great difference from traditional Ad hoc wireless networks,minimization of the energy consumption is a key problem for the practicality of WSNs.This article integrates the influence on the route discovery from hop counts,location and energy consumption.It presents a cross_layered approach which combines medium access organization with routing,and the simulation shows that the method will improve the network energy-efficiency.更多还原
