| 摘 要： | 无线传感器网络的径间干扰是多径路由亟待解决的重要问题,然而目前干扰避免策略的设计忽略了无线传感器网络最关心的能耗问题.本文提出基于梯度的MR2-GRADE路由协议框架,利用已建路径上各节点到目的节点的跳数构造干扰范围外节点的网络梯度,有效避免传统广播方式的高路由开销.针对基于梯度的局部路由决策导致后续路径创建成功率受网络节点分布密度影响较大的问题,设计了基于梯度的贪婪转发算法GRADE_GF和受限泛洪算法GRADE_RF.仿真实验结果表明:与已有的同类多径干扰避免路由相比,基于MR2-GRADE协议框架的路由可有效降低路由开销,随着网络规模扩大,优势越明显.

| Abstract: | Inter-path interference of Multipath routing in wireless sensor networks(WSNs) is a most important problem which needs to be solved urgently.However,energy cost,concerned most in WSNs,is ignored by current interference-free schemes.The grade-based routing protocol framework MR2-GRADE(Maximally Radio-Disjoint Multipath Routing based on Grade) proposed in this paper uses hops of nodes in leading path to construct grade of nodes beyond interference zone of this path and avoids high route cost caused by broadca... |
