Performance simulations of a mobile radio network using contention-based WIMA protocol under Rayleigh- and log-normal-fading environments
Chih-Yang Kao, Jeich Mar · IEEE Transactions on Vehicular Technology · 2002
The performance of mobile radio network using the contention-based wireless integrated multiple access (WIMA) protocol on a packet reservation basis for frequency division duplex (FDD) hierarchies in Rayleigh- and log-normal-fading environments is simulated. The contention-based movable-boundary WIMA protocol is applied for an exiting mobile radio network to provide the data service and to compare its expected data-packet delay with those of the fixed-boundary WIMA and General Packet Radio Service (GPRS) protocol. The simulation results demonstrate that the mobile radio network using the contention-based movable-boundary WIMA protocol to integrate voice and data services can reduce the expected data-packet delay. The analytical results are used to validate the simulation results.
