ABSTRACT
In order to ensure fair access and efficiency of bandwidth usage in wireless integrated networks, resource allocation algorithms should be well designed. In this paper, we briefly discuss the complete sharing, complete partitioning and Hybrid resource sharing approaches and their shortcomings in WiMax-WiFi integrated networks. To overcome these shortcomings we propose the Prioritized Resource Sharing algorithm for WiMax-WiFi integrated networks. In this algorithm, the channels are prioritized for different traffic classes rather than strict reservation or open access. The prioritized resource sharing algorithm is then extended to multiple integrated networks. Finally, we analyze the proposed algorithm by modeling it using two dimensional continuous time Markov chains. The simulation results indicate that the Prioritized Sharing model achieves the best system utilization compared to other algorithms. It is also observed that due to heavy traffic of one class of users, other class of users are not starved unlike in complete sharing
