摘要
分布式资源预留协议是UWB网络中一种重要的信道接入机制,其实现能为研究UWB网络性能提供仿真基础。本文分析了ECMA-368标准中的分布式资源预留协议体系,从结构体系、资源预约处理等方面着手,提出了一种在NS2仿真平台上实现该协议的设计方案。仿真结果表明,该方案有效地实现了DRP的基本功能,保证了资源的预留和节点之间业务流的可靠传输,为UWB网络仿真平台的实现打下了基础。
Distributed Reservation Protocol （DRP） is an important channel access mechanism for UWB networks which can provide a solid platform for the study of UWB networks. Based on the analysis of DRP, a design scheme to implement this protocol in NS2 platform is proposed from the view of system structure and resource reservation process. Simulation results indicate that this scheme can effectively realize the basic function of DRP, and ensure resource reservation between the devices and the reliable transmission of traffic flows between the nodes
