摘要：Rapid growth in telecom industry searching for new methods provide the better service to their customer here implementing proposes a multihop dynamic channel assignment (MDCA) scheme for time division multiple access (TDMA)-based multihop cellular networks. The proposed MDCA assigns channels are observed in ofdma system to the calls based on interference information in surrounding cells, provided by the Interference Information Table (IIT) in the network. Two different channel searching strategies, Sequential Channel Searching (SCS) and Packing based Channel Searching (PCS), for use in MDCA are proposed and studied. A channel reassignment procedure to further enhance the performance is also investigated. Simulation results show that MDCA significantly improves the system capacity. Furthermore, the MDCA can efficiently alleviate the call blocking in hot-spot cells.
