Channel Spacing for ACI control on 5 GHz WMN Backhaul

Abstract

In this paper, we formulate a channel assignment scheme for wireless mesh backhaul. The work deals to enumerate the effect of Adjacent Channel Interference (ACI) with proper channel space. The work considers interflow and interaflow links in the support of directional antennas for 802.11a backhaul. Interference nodes are identified by neighbouring directed graph and channel assignment problem is solved by using greedy algorithms. We evaluate work by simulations through OPNET modular 14. Framework of work could act as an imperative way to enhance the network performance. In contrast, the results shows that the proposed scheme offer meaningful throughput gains and significant decrease in delay with the selection of channel space to nodes. Obtained results shown that network performance raise and approximately twice as compared to system with adjacent nodes on consecutive order of channels.
