Abstract

Wireless Ad Hoc networks are relatively new and are gaining ground in research due to promises they offer. Wireless Ad hoc networks do not require predefined configuration and have no fixed infrastructure. They are self-organizing and self-configuring networks. Several protocols have been developed that vary in the performance and complexity. Most routing protocols for mobile ad hoc networks, such as: Ad Hoc On Demand Distance Vector Protocol (AODV), Dynamic Source Routing (DSR) are designed without explicity considering quality of service of the generated route. These routing protocols provide the capability for establishing minimum hop paths between nodes on a best effort basis regardless of QoS. In our work, we analyze the performance of these protocols and we present an efficient scheme for support QoS over MANET named Hierarchical Dynamic Source Routing protocol (HDSR). The performance aspects we study are fraction of routing overhead, end-to-end delay and throughput. It was shown via computer simulations that (HDSR) improves these performance aspects in wireless mobile ad hoc networks compare to other protocols.
