Including the effect of bit errors, hidden nodes and capture on the performance of the HIPERLAN CAC layer protocol for real-time traffic

摘要

The growing interest in wireless systems and networks has led to the first wireless LAN (WLAN) protocols. The medium access control (MAC) layer protocols of such protocol suites are of key importance. The Radio Equipment and Systems (RES) Technical Committee of the European Telecommunications Standards Institute has proposed the High PErformance Radio LAN (HIPERLAN) protocol suite. We present, study, analyze and evaluate the performance of the MAC layer of the HIPERLAN protocol suite for real-time data transfer. Simulation models that take into account the phenomena of hidden nodes, capture and bit errors are presented. Numerical results from the simulation models are presented, so that the issues involved are better understood.
