Issues, challenges and problems in channel allocation in cellular system

Abstract

Cellular communication has changed the dimensions of communication by offering the ease of ubiquity to the users. The bandwidth available for a cellular system is always limited. With the increase in multimedia applications and ever increasing demand of wireless devices supporting higher data rate flow, cellular systems, in general, always face scarcity of channels. In cellular systems, utilization of channels has been one of the very important areas of research along with power management, location tracking etc. Efficient and effective allocation of channels for cellular networks has become an extremely important topic of recent research. The different types of emerging services require real time support and uninterrupted communication, having more strict QoS requirements. In this paper we have explored different issues and challenges involved in channel allocations in cellular systems and also highlighted some of the channel allocation schemes proposed in the literature.

A Review on Hybrid Channel Allocation Schemes for Cellular Mobile Telecommunication Systems

“…Channel allocation schemes can be divided into a number of different categories depending on the comparison basis. On the manner by which co-channels are separated, they can be divided into fixed channel allocation (FCA), dynamic channel allocation (DCA), and hybrid channel allocation (HCA) [6]. In FCA schemes, the area is partitioned into a number of cells, and a fixed number of channels are assigned to each cell according to some reuse pattern, depending on the desired signal quality.…”
