摘要

高拓扑变化率的ad hoc系统使得路由极不稳定。然而，稳定性是一个重要的问题，特别是在设计具有QoS提供的路由时。近年来，小型、廉价、低功耗的GPS接收机实现了基于位置的自组织网络路由。在位置信息的帮助下，路由的稳定性得到了显著提高。研究了自组织网络中的QoS路由问题。我们提出了一种基于位置并提供QoS的路由协议。提出的QoS-GRID方案考虑两层网格系统配置，以降低每层移动传输功率，从而提高带宽利用率。仿真结果表明，QoS- grid在节省带宽的同时，建立了稳定的QoS保证路由。

A location based QoS routing protocol for ad hoc networks

An ad hoc system with high topology changing rate makes routing extremely unstable. However stability is an important issue, especially for designing a routing with QoS provision. Recently, the availability of small, inexpensive, and low-power GPS receivers realizes location based routing for ad hoc networks. With the help of location information, the routing stability is significantly improved. The paper investigates the QoS routing problem in ad hoc networks. We propose a location based routing protocol with QoS provision. The proposed scheme, named QoS-GRID, considers a two-tier-grid system configuration to reduce each mobile transmission power so as to enhance the bandwidth utilization. Simulation results show that QoS-GRID establishes a stable QoS guaranteed route and meanwhile saves bandwidth.
