Abstract :

In cognitive radio network tcp good put is one of the measure issues to improve the performance of the CR network. However most research work concentrated on performance improvement of tcp has two weaknesses as follows:-The underlying parameters are only considered to increase the TCP goodput, keeping the transport layer parameter unchanged. The second is formulated as the markov decision process in which the complete knowledge of the network is to be known. Hence to solve the above problem a POMDP base algorithm is proposed in this paper. In this proposed work each CRN users autonomously decides modulation type and power to be transmitted in PHY layer, channels which is to be selected in MAC layer to get best TCP Good put. As the channel is free space and the environment has perception error, this issue is formulated as Partial Observable Markov Decision Process (POMDP). Simulation result shows that the network can learn the optimal policy to improve the tcp good put in cognitive radio network.
