CBRA: A Novel Game Theory, Cell-Degree based Resource Allocation Mechanisms in WiMax Wireless Network

摘要

Now-a-days, WiMax becomes one of the hottest broadband wireless technologies. Resource allocation plays a vital role in IEEE 802.16, which enhances cell degree and overall throughput of the system. In this paper work, a novel game theory, cell-degree based resource allocation (CBRA) methodology is proposed. The User/Base Station (BS) assesses the data rate, and the QoS parameter such as bandwidth, latency, jitter, cell loss ratio, cell error ratio. Subsequently, the comparison of BS by User Equipment (UE) is scrutinized to estimate the cell degree with the high value of BS. The degree of user SINR dispersion is introduced as the major parameter for allocating the resource. Also enhanced the fairness of the users, by acquiring a fair share of system resource along with the relay station (RS). The experimental analysis depicts that the proposed CBRA algorithm which incorporates the network throughput, user fairness and game theory. This accomplishes higher network throughput to bandwidth consumption ratio than the existing greedy approaches.
