Capacity and delay in mobile ad hoc networks under Gaussian channel model

Abstract

We study the asymptotic delay and throughput in mobile ad hoc networks where η ad hoc nodes are distributed uniformly on a 2-D square (torus) region of area η. The communications between nodes are characterized by Gaussian Channel model, instead of the simplified protocol model or physical model. The mobility of nodes is characterized by two general broad classes of practical mobility models, i.e., hybrid random walk models and discrete random direction models, which generalize many mobility models used in the literature. Our results either fill the gap in this area or generalize a stream of milestone results on asymptotic capacity, delay, and the tradeoffs developed recently.
