Abstract: Resource Allocation is a kind of scheduling technique of balancing the multiuser channel spectral efficiency and feedback load. This paper addresses the problem of traffic inelasticity in dynamically configured network and its impact on Average Spectral Efficiency losses. Allocating fixed bandwidth to meet dynamic user requirements will lead to communication overhead. This paper proposes the problem of traffic inelasticity by routing the dynamic user to utilize the neighbourhood base station. Dynamic bandwidth allocation for user sub channel is optimally controlled by a global router which tracks and monitor the status of various base station within its coverage area, the over flow of user requirements of a base station is balanced by routing the excess user sub bands to the ideal or available neighbour base stations assuming synchronizations between these base stations, which increases the individual base stations spectral efficiency and reduces the hardware overhead. The performance evaluation of two scheduling schemes “On Off Based Scheduling”-(OOBS) and “Switched Based Scheduling”-(SBS) has been introduced and the switch based scheduling scheme is proved as comparatively efficient.
Keywords: Multi-user scheduling, bandwidth allocation, feedback load and spectral efficiency.
