  • Performance analysis and enhancement of an ultra-wideband WPAN MAC in the presence of noise

  • Ingår i: XI International Symposium on Problems of Redundancy in Information and Control Systems. - Saint Petersburg. ; , s. 117-122
  • Konferensbidrag (refereegranskat)abstract
    • This paper addresses the performance evaluation of the contemporary UWB WPAN standard. The basic standard functionality is described for which a system model is derived that accounts for the possible errors due to the background noise. Two realistic scenarios of the saturation conditions and the Bernoulli packet arrivals are considered to calculate the system throughput and the mean initial packet delay. The redundancy-based error detection mechanism that is implemented in the standard is discussed that allows the enhancement of the system performance. The obtained results are compared against the simulation which shows a good accordance with the analytical results and a distinct superiority of the introduced enhancement.

  • Performance analysis of a high-speed ultra-wideband WPAN MAC
  • 2007
  • Ingår i: Proceedings of the 14th International Conference on Analytical and Stochastic Modelling Techniques and Applications. - Sbr.-Dudweiler : Digitaldruck Pirrot GmbH. - 095530184X - 9780955301841 ; , s. 44-49
  • Konferensbidrag (refereegranskat)abstract
    • The current paper addresses the problem of the throughput-delay performance of a contemporary WPAN MAC standard. A brief overview of the standard functionality is first presented that allows a system model derivation. Two different acknowledgement policies are described under which the channel operation is considered. Two possible input traffic models are also considered one of them being saturation conditions under which the performance analysis is done that is further verified by means of the simulation. The obtained results show the system behavior as the number of channel users increase and allow the tuning of the protocol parameters to improve the performance.
