A Design and Performance Evaluation of a Class of Channel Reservation Techniques for Medium Access Control Protocols in High Bit-Rate Wireless Communications

摘要

This paper introduces 12 channel reservation techniques for medium access control (MAC) protocols suitable for high bit-rate wireless communication systems. The first 7 algorithms, namely CFP, CAP, COP, COP+SPL, CFP+SPL, UNI and UNI+LA, are applicable to systems with single-access chance per frame, whereas the other 5 algorithms, namely MT-CFP, MT-CFP+SPL, MT-UNI, MT-UNI+LUA and MT-UNI+LUT are suitable for systems with multi-access attempts per frame. The performance of these techniques are analytically evaluated and compared with the existing known techniques. The analytical model derived here are also validated through Monte Carlo computer simulations. Numerical results show that all proposed techniques are in general more superior to conventional reservation techniques. Finally when comparing between all proposed schemes in terms of both throughput performance and practical feasibility it is found that the MT-UNI+LA scheme are relatively efficient and suitable for practical applications.
