Multihop routing in wireless ad hoc networks creates situations in which some nodes know the content of packets being transmitted by neighboring nodes. This knowledge enables simplified interference cancellation schemes that can be used to schedule additional transmissions in the network. This approach, which we call overlapped transmission, can significantly improve the performance of ad hoc networks...
IEEE 802.11 DCF has been widely used in wireless multi-hop ad hoc networks as the medium access control protocol. However, how well it can perform has not been well studied. In this paper, we first propose a new Markov chain model to analyze the per-node throughput by taking into consideration three important issues in multi-hop networks, i.e., physical carrier sensing threshold, signal-to-interference...
