We consider the realtime services over on-demand routing protocols in ad hoc networks, where infrastructure does not exist and the network topology is highly dynamic and time-varying due to node mobilities. To reduce the end-to-end delay, we have proposed two efficient routing protocols: MSR (Multipath Source Routing) and RSR (Redundant Source Routing) in our previous work. Simulations have shown...
In this paper we devise efficient optimization techniques to find optimal routing and scheduling policies for wireless ad hoc networks in the presence of multi-user interference and cooperative transmissions. Our focus is to assess the impact of interference among distinct data flows on optimal routing paths and related transmission schedules. In our reference scenario, all nodes have a single antenna...
Capacity of Mobile Ad Hoc Networks using a single channel and a single interface reduces due to channel interference and collision. Use of multiple non overlapping channels increases the network capacity by allowing more concurrent transmissions. A single interface together with multiple channels results in high switching delay. As a result multiple interfaces should be used to reduce the switching...
In mobile ad hoc networks, multipath routing improves end-to-end throughput through parallel transmission on multiple paths, which is affected by path inter-path interference. This paper proposes a routing protocol IBMR (interference- and bandwidth-based multipath routing), which maximizes the available bandwidth of the path between source and destination, and minimizes the interference between the...
