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

Abstract

Mobile phones are now inexpensive, easy to use, and comfortable and capable of providing every latest feature we desire. Now a days, mobiles phones are equipped with number of applications to provide these features. Even the voice call in a mobile phone is just an application now. To get these features with good quality it is mandatory to have good connectivity with the backbone network. The tremendous growth of the wireless/mobile user population, coupled with the bandwidth requirements of multimedia applications, requires efficient allocation of the scarce radio spectrum to the wireless/mobile network. The mechanisms are based on the basic channel allocation schemes like Fixed Channel Allocation, Dynamic Channel Allocation, and a Hybrid or a Borrowing Channel Allocation. A Hybrid Channel Allocation scheme is the best mechanism to manage the channel cost effectively. Few basic hybrid channel allocation schemes are compared here to evaluate the network performance in terms of call processing and call dropping
