A Multihop Dynamic Channel Assignment Scheme For Cellular Network
Chetan D. Jadhav, Anupam Joshi · 2013
A multihop Dynamic Channel Assignment Scheme is proposed here for Multihop Cellular network. The proposed scheme splits the cell into microcell and macrocell to accept and complete the call as single hop, two hops, or three hops call. The radio resources are assigned to each call based on the interference information in the surrounding cells, stored in Interference Information Table at MSC. Two different channel searching algorithms, namely, Sequential Channel searching and packing based Channel searching are proposed and studied here. Such schemes with channel re-assignment procedure to further enhance the system performance, is also investigated. The MDCA scheme for significant improvement of system capacity and call blocking probability is simulated and studied. Further the situation of Hot-Spot is also studied for avoiding call blocking.
