| Abstract: | Multichannel ALOHA protocol is a generalization of the single channel one is be-lieved to be a good candidate for the data protocol in hybrid voice/data microcellular systems.In this paper ,results of investigations on the performance of a multichannel ALOHA system in the microcellular environment are presented,accounting for channel impairments,the spatial distribu-tion of mobile users,and the capture effect.A Markovian model is established,several perfor-mance measures are defined,and an iterative method is proposed to evaluate the system perfor-mance numerically.The stability of this multicell ,multichannel ALOHA system is also studied,using the total delay as the criterion. |
