On the performance of a novel multi-hop packet relaying ad hoc cellular system

A novel architecture for connectionless packet-based communication in wireless mobile cellular system is studied. A certain number of data relaying stations (DRS), which can relay packets from one cell to another in a manner similar to the ad-hoc multi-hop relaying mechanism, are placed in the cellular system to balance traffic load between neighboring cells. The placement of DRS is carefully studied to provide a full relaying coverage of the cell area with the minimum number of DRS. According to a distributed delay-sensitive relaying control strategy, mobile stations (MS) can locally decide whether to divert their traffic to neighboring cells without any central control. Simulation results demonstrate that the proposed method can significantly improve the system throughput and resource utilization and reduce the average packet delay.
