Executive Summary

This paper focuses on performance evaluation to study the effects of the resource management strategy in ad hoc networks. The presented strategy is a result of the new outlook on the IEEE 802.11 networks capabilities and performance enhancement. The proposed solution is dedicated to real-time services support and is based on the concept of the Resource Manager that organizes and controls the whole traffic in the network. Novel procedures were developed and applied in order to organize the network and manage the real-time traffic. A method for measuring and estimating available bandwidth was introduced. This method provides wireless station the capability of measuring the bandwidth independently of other stations in the network.
