Interference Aware Resource Allocation in Relay Enhanced Broadband Wireless Access Networks

Abstract

First, a novel interference aware routing metric for multipath routing considering both interflow and intraflow interference will be discussed. Second, in order to ensure quality of service (QoS), an interference aware max-min fair bandwidth allocation algorithm is addressed using lexicographic ordering and optimization. A comparison among various interference based routing metrics and interference aware bandwidth allocation algorithms established in the literature is shown through simulation results derived from NS-2 and CPLEX. It is shown that the proposed interference aware resource allocation framework improves network performance in terms of delay, packet loss ratio, and bandwidth usage. Lastly, future challenges and emerging research topics and opportunities are outlined.
