Abstract:
In a cellular system, a base station can smoothly communicate with nodes in its cell by avoiding overlap of frequency range with its adjacent cells. From the viewpoint of graph theory, that needs to divide the original frequency range into at least four sub-ranges. This leads to deteriorate the transmission rate. To tackle this problem, we propose Complete Cell Partitioning (CCP) that enables a base station to use the whole of the original frequency range by avoiding overlap of its own cell with the adjacent cells. CCP is achieved by appropriately controlling the transmission power on base stations. We first analytically derive success probability of CCP when nodes are randomly located in the whole region. Then, we verify the analysis by comparing with simulation results. The analytical and simulation results show that CCP enables to use the original frequency range more effectively than the traditional cellular system regardless of the number of nodes in a cell.
