Abstract

Abstract. Providing efficient access to a large user population with variant service requirements in wireless communications networks poses a very challenging problem. Resource allocation in the wireless domain should take into account bandwidth limitations and fading effects inherent to wireless channels, while accommodating for resource constraints encountered in wireline networks. In this paper, a fuzzy resource allocator is proposed in order to facilitate the efficient allocation of network resources in the wireless domain. The network preferentially allocates its resources to real-time (RT) traffic sources. Using effective transmission rate statistics of non realtime (NRT) trafficd sources as a measure of fading channel conditions, the fuzzy allocator optimally allocates the remaining resources to NRT traffic. Simulations show that the fuzzy allocator can reduce delay and incurs fewer retransmissions for NRT traffic. An overall improvement in wireless channel utilization is demonstrated.
