RADIO RESOURCE ALLOCATION IN RURAL GSM NETWORKS

Technological  advances  and  rapid  development  of  handheld  wireless  terminals  have facilitated the rapid  growth of wireless communications. The tremendous growth of the wireless/mobile user population, coupled with bandwidth requirements requires efficient use and reuse of the radio spectrum allocated. Efficient use of a spectrum is important from the cost-of-service  point  of  view,  where  the number of  base  stations  needed  to  service the geographical region is an important factor.

To efficiently use the spectrum, different radio resource allocation schemes are employed to allocate channels in a GSM network. This paper points out the different allocation schemes and concentrates on the Distributed Dynamic Channel Allocation Scheme (DDCA) for the rural environment which is a representation of light traffic areas. The main goal is to design and show how call blocking and call dropping rates can be minimized thus improving the network’s quality of service (QoS).
