Dynamic resource allocation in time-varying ultra wide band channels

When considering applications requiring QoS it is crucial to adopt in the MAC adaptive resource allocation strategies in order to reduce system load. This paper proposes an analytical procedure for optimizing resource allocation in the case of mobile Ultra Wide Band (UWB) users in an indoor environment. The proposed analysis incorporates both the user mobility model and the UWB time-varying channel model. The proposed resource allocation algorithm is based on an iterative algorithm which is capable of minimizing required capacity according to both the state of the channel and the requested QoS. Results of simulations show that within reasonable speed limits which can be quantified, the algorithm is capable of providing the system with an excellent fit of assigned resource vs. required QoS.
