Abstract

Cooperative transmission can improve the performance of wireless ad-hoc systems due to its spatial multiplexing gain. Given that multiple cooperative relays which belong to the same source-destination pair can transmit simultaneously in the cooperative transmission, it is different from normal data transmission in which only one source node transmits in a single source-destination pair. Therefore, a new distributed scheduling algorithm for wireless ad-hoc systems should be devised. To this end, we propose a distributed scheduling algorithm for wireless ad-hoc systems with cooperative transmission in which multiple cooperative relays can transmit at the same time by using Amplify-and-Forward or Decode-and-Forward scheme. By using the elastic exclusive distance which is the minimum distance between two active cooperative transmission sets, the outage probability of cooperative transmissions can be greatly reduced compared to that of conventional scheduling scheme. Through performance analysis and simulation results, we show that the proposed scheme can enhance the performance of the system.

多中继协同传输的分布式调度算法
协作传输由于具有空间复用增益,可以提高无线自组织系统的性能。在协作传输中,多个属于同一源-目的对的合作中继可以同时传输,这与一般的数据传输中只有一个源节点在单个源-目的对中传输不同。因此,有必要设计一种新的无线自组织系统分布式调度算法。为此,我们提出了一种适用于无线自组织协作传输系统的分布式调度算法,其中多个协作中继可以采用放大转发或解码转发的方式同时传输。利用弹性排他距离,即两个主动协同传输集之间的最小距离,与传统调度方案相比,可以大大降低协同传输的中断概率。通过性能分析和仿真结果表明,该方案可以提高系统的性能。
