ABSTRACT:
We analyze the outage performance in finite wireless networks. Unlike most prior works, which either assumed a specific network shape or considered a special location of the reference receiver, we propose a general framework for analytically computing the outage probability at any arbitrary location of an arbitrarily-shaped finite wireless network: a reference link power gain-based framework which exploits the distribution of the power gain between the reference transmitter and receiver. The boundary effects are accurately accounted for using the exact probability distribution function of the distance of a random node from the reference receiver in finite networks. For the case of the node locations modeled by a uniform Binomial point process and independent and identically distributed Nakagami-m fading channels, we demonstrate the use of the proposed framework to analytically evaluate the outage probability at any location in the network of either a disk or polygon shape. Our framework generalizes and reproduces many existing results in the literature. The analysis illustrates the location-dependent performance in finite wireless networks and highlights the importance of accurately modeling the boundary effects.
