Resource Allocation in User-Centric Wireless Networks

Abstract

This paper presents a behavioral fairness-based resource allocation (RA) algorithm for uplink transmission of a multiuser orthogonal frequency division multiplexing system. The aim of fairness- based RA is to boost users' willingness to start and keep cooperating with each other and behave well to keep their trust and reputation high. An interesting notion of differentiated streams is also included in the proposed RA, which can fine-tune RA result to transfer excess bandwidth and power from real-time streams to non-real-time streams, i.e. increase useful throughput. In order to reduce the complexity of RA, a set of contiguous subchannels are grouped into a chunk to allocate resource chunk by chunk. The effects of users' contribution and the number of subchannels grouped in a chunk on the average throughput is analyzed and shown by numerical simulations
