Analysis of achievable capacity in irregularly-placed high performance mesh nodes

Abstract

Research has shown that the capacity of the wireless mesh network improves with the increase of number of radio interfaces per node and the multiplicity of the non-overlapping frequency channels. Recently, such high performance nodes (HPNs) have been successfully deployed in many areas including the rural South Africa. However, the problem of finding the achievable capacity of such network deployments, taking into account multipath channel links and irregular placements, has been considered a challenge. This paper derives the achievable capacity limit of such HPNs’ placements. The analytical results show that the network capacity increases with the irregularity of HPNs placements, the number of antennas as well as the multiplicity of radios per HPN. Compared to the recent analytical results in literature, the HPN showed a superior end to end numerical capacity.
