Abstract :
This paper presents an analytical model for a multi-hop two-dimensional (2-D) network with finite density of nodes communicating with one another by forming an opportunistic large array (OLA). Transmission among these nodes is modeled via Markov Chain, where the wireless channel is considered as a composite lognormal-Rice random process. We approximate the sum distribution of the received power at a node with lognormal random variable (RV) using a moment generating function (MGF)-based approach, which is acquired by using Gauss-Hermite integration. The transition probability matrix is derived to determine the one-hop success probability. Coverage aspects for different arrangement of nodes is quantified along with the effects of wireless channel on system performance.
