Abstract
In this paper, the performance of opportunistic relaying in a dual-hop decode-and-forward (DF) network where the intermediate nodes are distributed according to a homogeneous Poisson point process with fixed density is analyzed. A sectorized selection region is considered, where the best relay is selected among those potential nodes that lie in this region. In particular, the density of the potential nodes and the closed-form expression for outage probability of the system with maximal ratio combining (MRC) receiver at the destination, is derived based on the theory of point processes. Our results show that, as expected, MRC receiver outperforms the selection combining (SC) receiver at spatially random networks. The results of this paper are attested through Monte-Carlo simulations.
