Because of the burgeoning increase for data communication and multimedia services over wireless links, and rapid growth of wireless communications, many researches have been undertaken to find effective integrated protocols that satisfy this demands. Since wireless links normally show higher bit error rate and temporal disconnections compared with wired links, the losses are greater, this may also be caused by the mobility like handoff, and many wireless channel impairment errors and not just congestion. TCP deals with packet losses by applying congestion control mechanisms, which tends to degrade its performance. Many protocols have been proposed including Snoop, to alleviate this problem. Our objectives here are to study and enhance the Snoop protocol using the modified ACK called Fake Acknowledgment under various network parameters. iv In this thesis, a Fake ACK technique proposed based on the Snoop Acknowledgment procedure; this reduces the waiting time of the Fixed Host waiting for the right Acknowledgment to be received, and hence reducing the probability of initiating congestion control mechanism. The results show that the throughput of our technique is increased and the losses are decreased compared to traditional Snoop protocol, under different parameter values.
