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 selforganizing 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 explicitly 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. There is a new proposed scheme named Hierarchical Dynamic Source Routing (HDSR) supporting Qos over mobile ad hoc network (MANET) has been attracting significant current research interest. In our work, we evaluate the aspects of Qos concerning this protocol compared to the other schemes. The performance aspects we study are fraction of routing overhead, end-to-end delay, total capacity, MAC control packet capacity and throughput. We have shown that distribution of Forward Nodes (FN) in the network is important for optimization of the performance figures. We present an efficient and adaptive FN selection mechanism for HDSR as well as optimization of number of FNs in a given scenario.
