Resource allocation for heterogeneous traffic in a wireless network
Erik E. Anderlind · 2002
We propose a distributed algorithm for radio bandwidth assignment to a user population where bandwidth requirements can vary substantially between different users. The performance is compared, on merits of blocking and total network throughput, to that of a similar network employing a fixed number of channels per cell. The results show that bandwidth utilization increases by an order of magnitude. The throughput of the adaptive schemes are, as opposed to the fixed allocation scheme, fairly insensitive to variations in the traffic mix. Traffic and interference adaptive resource allocation schemes appear necessary in wireless networks in order to obtain reasonable performance for large bandwidth users.
