Bandwidth and Transmit Power Allocation for QoS Support in Wireless Networks

With the continued increase of speed and capacities of computing devices and the growing needs of people for mobile computing capabilities, allocation of resource plays a vital role in research community. Quality of service (QoS) provisioning in MANETs is an essential component needed to support multimedia and real-time applications. Maximizing the utility of the traffic flow is a challenging problem. To overcome this problem a new framework was designed. This framework achieves the maximum utility of the flow by considering Channels, Transmission power levels and Bandwidth as the parameter. The framework uses two methods. One is cross decomposition approach to overcome the problem due to self-interference of the packets. We build admission control along with this method which avoids congestion in network by only admitting requests which do not cause self interference. This cross decomposition approach compared with Utility based allocation to find the optimal solution. This algorithms act as designing guidelines for resource allocation of QoS traffic in a wireless network, which take into account the total available resource of network, the users’ traffic characteristics, and the users’ channel qualities. This work focuses the resource allocation in terms of Channels, Transmission power and bandwidth. A comparison between both the methods is also performed.
