Optimization of ARQ Mechanism in Wireless Relay Network

Abstract:

In this paper we do some researches on the ARQ mechanism which provides the probability of involving the relay nodes into the UWB multi-hop network. The ARQ mechanism we designed combines PWMR ARQ and Relay ARQ, which can perform on both the end nodes and relay nodes. Then we make a theoretical analysis of the indoor UWB channel model and give a Finite-state Markov linker layer model. With the simulation results, we can get the conclusion that using ARQ mechanism designed in this paper significant enhances throughput, time delay and bandwidth utilization of the UWB multi-hop network.
