Quality of service for ad hoc wireless network

Wireless networks represent the new computer paradigm. They have as main function to provide users with permanent access, independently of their physical location. With the decrease in the costs of portable devices and the increase in their capacity, a new concept called ad hoc network appeared. Through this technology, communication is made directly between mobile computers. In this paper, the proposal and validation of a mechanism based on the bandwidth management principle are done to guarantee QoS (Quality of Service) in ad hoc wireless networks. Therefore, a software is developed to simulate ad hoc environments, making connections following the approach of the already proposed mechanism. Several experiences demonstrating the advantages of this method were carried out. They proved that this method guarantees a better use of the transmission channel and, at the same time, accepts more connections.
