摘要

在无线自组织网络中，当节点被赋予单个半双工无线电时，引入了并行交互介质访问(PIMA)协议，该协议可以并行地向多个目的地发送多个数据包，也可以使用OFDMA并行地从多个发送器接收多个数据包。分析和仿真结果表明，与MAC协议相比，PIMA在信道吞吐量方面取得了巨大的进步，MAC协议旨在通过传统的信道交换技术实现多信道网络的并发性。

Parallel Interaction Medium Access for Wireless Ad Hoc Networks

The parallel interaction medium access (PIMA) protocol is introduced to orchestrate channel access in a wireless ad hoc network when nodes are endowed with a single half- duplex radio, and can either transmit multiple packets to multiple destinations in parallel or receive multiple packets from multiple transmitters in parallel using OFDMA. Analytical and simulation results indicate that PIMA attains tremendous improvements in channel throughput compared to MAC protocols aimed at attaining concurrency via traditional channel switching techniques proposed in the past for multi-channel networks.
