This paper describes the concept of the resource management strategy in ad hoc networks for rescue operations. The presented strategy is a result of t he 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 c oncept of the Resource Manager that organizes and controls the whole traffic in the network. Novel procedures were devel oped and applied in order to organize the network and manage the real time traffic. A method of the available bandwidth measurement and estimation was introduced. Large scale simulations for different numbers of Voice over IP (VoIP) sources and various voice codecs have been carried out. They show the increase of channel utilization reaching o ver 80% and significant growth of the network capacity.
