Random access transport capacity of dual-hop AF relaying in a wireless ad hoc networks

Abstract

To account for randomly distributed nodes in a wireless ad hoc network, the random access transport capacity is defined as the average maximum rate of successful end-to-end transmission over some distance. In this paper, we consider a random access transport capacity for a dual-hop relaying to find the end-to-end throughput of wireless ad hoc network, where each node relays using Amplify-and-Forward (AF) strategy. In particular, we also present the exact outage probability for dualhop AF relaying in the presence of both co-channel interference and thermal noise, where interferers are spatially distributed following a Poisson distribution. Intriguingly, even though transmitting nodes increase, numerical results demonstrate that the overall throughput of dual-hop AF relaying decreases due to interference. Moreover, it is noted that the dual-hop AF relaying is still beneficial in terms of the random access transport capacity in wireless ad hoc networks.

Capacity analysis for multi‐antenna dual‐hop AF system with random co‐channel interference

“…Inspired by the framework in [7], enormous works have been done by considering the randomness in networks [8, 9]. The outage probabilities and spatial diversities of ad hoc systems were analysed in [10, 11].…”
