Outage connectivity with collaboration in wireless ad hoc networks

Abstract

This paper analyzes the connectivity of wireless ad hoc networks in both a non-cooperative scheme and a cooperative scheme. Assuming that nodes are randomly distributed with a Poisson process, the probability of full connectivity in a system can be raised by increasing the number of connectional trials at each node. Even though an infinite number of trials guarantee full connectivity in a system, it is not of practical concern because it may require infinite power and infinite delay. Instead, this paper analyzes the required number of connection trials for full connectivity mathematically and experimentally. In addition, this paper proposes a cooperative scheme to maximize the benefit from collaboration among nodes and simulates its results.
