Along with information technology of flourishing, the popularization rate of wireless communication equipment is higher.However, WiMAX is the one of new broadband wireless technologies.The performance of mobile WiMAX system is highly dependent on channel assignment scheme because frequency spectrum is finite in wireless communication systems.There are two exist channel assignment scheme in WiMAX namely No Prioritized Scheme (NPS) and Reserved Channel Scheme (RCS).In this paper propose new channel assignment scheme namely Temporal Reserved Channel Scheme (TRCS) for improve performance of channel assignment scheme in WiMAX.Performance of channel assignment scheme in WiMAX depend on four probabilities such as Blocking Probability (๐ ๐ ), Handover Failure (๐ โ ), Forced Termination Probability (๐ ๐๐ก ) and Probability of Not Completed Calls (๐ ๐๐ ).
