多跳无线网中基于空分TDMA的时隙分配策略

空分TDMA（STDMA）是基于TDMA的信道接入协议,该技术被应用于实时性要求较高的多跳（multi-hop）无线网络中,并可使多个在地理位置相互独立的移动终端使用相同的时隙来增加网络容量,不同移动终端之间的数据传输通过对终端调度安排来实现。调度算法一般分为基于节点或基于链路的分配方式。对这两种方式对比发现,在一定条件下两者都有不理想的特性。因此,结合两种方式优点提出了一种新颖的分配策略。仿真结果表明：该分配策略在高业务负载情况下能满足链路分配的高吞吐量,也能达到低业务负载下节点分配的低延迟。

Slot Assignment Strategies of Spatial Reuse TDMA in Multi-hop Wireless Networks

In the multi-hop radio networks,spatial reuse TDMA is proposed as an access scheme.The idea is to increase capacity by letting several radio terminals use the same time slot when possible.A time slot could be shared when the radio units are geographically separated such that small interference is produced.In reuse scheduling,there are several alternative assignment methods.Traditionally,transmission rights are given to nodes or to links.A comparison of these two approaches is given,and it shows that both ha...
