HMM based resource allocation and fuzzy based rate adaptation technique for MANET
چکیده انگلیسی

In mobile ad hoc network (MANET), each transmission demands different quality of services to reduce the throughput. This can be overcome through effective resource allocation technique in the network. In order to improve the network performance, rate adaptation mechanism is required. Hence, it is proposed the resource allocation and rate adaptation techniques for MANET using MAC protocol. In this technique, the free available bandwidth in the channel is predicted based on the current traffic load of the nodes using hidden Markov model (HMM) technique. New users are admitted after checking the predicted available bandwidth against the demand of each user. The rate adaptation is performed by estimating the physical transmission rate using fuzzy logic technique. By simulation results, it is shown that the proposed technique enhances the network throughput and performance.
