Abstract

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.
