Abstract :
Data transmission in ad hoc networks involves interactions between MAC-layer protocol and data forwarding along network-layer paths. These interactions have been shown to have significant effect on system throughput and source queue characteristics. In this paper, multipath data transmission is studied and analyzed based on the DCF in IEEE 802.11 MAC protocols. Analytical models are developed to demonstrate the frame service time and the queue characteristics in the source station under unsaturated conditions for two frame arrival processes (Poisson and deterministic) and two packet generation processes (round robin and batch). The throughput in the multipath multihop system is also investigated and a bound of it is derived. These models are all validated by means of simulation under various scenarios
