Dual-Radio传感器网络链路调度算法的研究
Study on link scheduling algorithm in Dual-Radio wireless sensor networks
摘要
Abstract
Considering the fact that both the orthogonal channels and the number of radios in a sensor node are limited in wireless sensor networks, a distributed Channel Allocation(CA) algorithm for Multi-Sink Dual-Radio WSNs is presented.Based on CA, a Link Scheduling(LS) algorithm is proposed in this paper as well.Based on the number of hops from nodes to the Sink, the networks are divided into different levels, which form hierarchical networks.CA avoids conflictions within different levels,and LS avoids conflictions within same level.CA and LS implement the data parallel transmission with zero-conflict,and it can finish the data collection in wireless sensor networks in a preferable way.Experiment results indicate that CA and LS can reduce the data collection time obviously,and hence increase the throughput of the networks.关键词
