QoS assurance with colocated wireless access points

The proposed research aims to provide the technical framework which will enable multiple Wireless LANs to provide the assured network service while being in communication range of each other. The Access Points involved compete and cooperate while keeping the overall goal of maximum system utilization above individual optimization. We use channel access time as the means of resource allocation, while keeping the system modular so that any other unit can also be used without changing the protocol. We provide a secondary protocol to ensure robustness of our main algorithm for Access Allocation. We also propose a model to measure Transport Level Goodput with the help of MAC level parameters. In turn, we also derive MAC level performance in terms of the physical environment characteristics such as number of other stations, APs and their clients. Although simple estimates based on current Internet conditions can be made already, our work helps us estimate the performance which can be assured to clients with a much higher accuracy. This result can be independently applied to model the performance of any
