摘要:

传感器网络把各种各样的微型传感器设备通过Ad Hoc网络连接起来,以便完成某些特定任务。但是,由于Ad Hoc无线网需要通过共享信道来实现节点间的通信,所以本文基于节点之间可能存在的信道干扰研究了:给定一个源和目的节点对的集合{(si,ti)},怎样在链路层上对从源到目的的数据流进行调度,以使带宽资源得到充分的利用,并设  计了链路的调度算法。

Abstract:

A wireless sensor network is composed of various wireless sensor devices and is cormected by ad hoc networks. These devices communicate with each othe r through a shared bandwidth. We study the interference among sensor nodes: given a collection of source-destination pairs { (si, ti)}, how to schedu
ule the flow which can transfer data from the sources to their corresponding destinations more efficiently? We also give a corresponding link schedulin  ng algorithm.
