Resource scheduling algorithms for LTE using weights

A smartphone without Internet is obsolete in today's world. With multitude of applications hosted in the personal handheld devices, the need of high speed Internet access has increased manifold. On one hand, in order to meet these demands, LTE-A (a.k.a. 4G) started a new era of improved network capacity as well as higher bandwidth availability to each user, while on the other hand the resource allocation for users has emerged as an active research area. Parameters such as number of users, channel conditions, type of traffic class and so on play an important role while designing a scheduling algorithm. In this paper, LTE resource scheduling algorithms from the literature are presented with their pros and cons and Inverse Weighted Fair Queuing (IWFQ) as well as Proportional Fair Inverse Weighted Fair Queuing (PFIWF) algorithms are proposed. Also, simulation results are shown to outperform the existing algorithms and finally, fair distribution of radio resources and the overall system throughput by effectively using the radio frequency spectrum is outlined.
