Resource allocation for heterogeneous traffic in a wireless network

Multimedia traffic in future wireless networks will require an efficient use of the radio frequency bandwidth. We propose a distributed and adaptive radio bandwidth assignment algorithm for a user population where the bandwidth requirements can vary substantially between different users. The performance is compared, on the merits of blocking and throughput, to that of a similar network employing a fixed number of channels per cell. The results show that the bandwidth utilization increases by an order of magnitude, by far more than for fixed (narrow) bandwidth schemes. Traffic and interference adaptive resource allocation schemes appear necessary in wireless networks in order to obtain reasonable performance for large bandwidth users
