基于功率控制的WSNs跨层方案
摘要
无线传感器网络(W SNs)协议设计中既要考虑网络性能
又要考虑能量消耗。由于考虑的因素众多
传统的分层方法通常不能满足多个目标。提出一种基于功率控制的跨层路由方案
基于微经济学中效用的概念
通过对每个链路的功率进行控制
减少不必要发送功率
减少节点之间相互干扰
节省能耗。通过基于效用的路由度量
均衡网络性能
延长网络生存期。
Abstract
When designing wireless sensor networks(WSNs)protocol
not only network performance is considered
but also energy consumption is considered.Tradition layered design method can not satisfy several object parameters in the same time.A cross-layer scheme based on power control is proposed.It can reduce unnecessary energy and the interference between nodes by control power of every links.It can avoid selection of the route of lower battery capacity
which can improve overall network performance.
