Adaptive Shared Channel Assignment Scheme for CellularNetwork to Improve the Quality of the Handoff Calls
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2015, Vol 17, Issue 1
Abstract
Abstract: In this paper, an adaptive channel assignment scheme is proposed to ensure the quality of servicesfor the wireless networks. The proposed scheme divides the channels into two categories, the guard channelsand the shared channels. The number of guard channels is estimated by the Markovian model in order to keepthe handoff calls higher priority. The remaining channels, called shared channels, can be used by both newcalls and handoff calls. The proposed scheme based on incoming rates of handoff and new calls allocateschannels for guard and shared channels. In addition, this approach is able to provide quality of serviceguarantee in terms of handoff dropping rate. From the simulation, the proposed scheme significantly improvesthe dropping rate and the blocking rate in comparison with the existing methods.
