Multipath on-demand routing protocols for mobile ad hoc networks try to reduce control overhead and end-to-end delay by computing multiple paths with a single route discovery process. We propose Graph-based Multipath Routing (GMR), a novel multipath routing protocol that generate the network topology graph to compute all link disjoint paths in the network.(More)
Recent developments in networking technologies, coupled with the advent of high-capacity storage devices and improved coding schemes, will make it feasible to provide many advanced multimedia communications services. Among future telecommunication services, the VOD (Video On Demand) service is emerging as one of the most promising services. In this paper,(More)
Wireless data services are fundamental in ubiquitous networks. In wireless data networks, the TCP congestion mechanism can mistake a wireless channel error or blackout for congestion on the route. Several wireless TCP protocols have been proposed considering TCP performance degradation in wireless systems. However, these protocols are too complex to deploy(More)
