Abstract:
In wireless relay networks based on IEEE 802.16j, each relay node has its own service area that provides wireless Internet access service to the client terminal. The performance of such networks is heavily affected by how each relay node determines its service area size. In order to determine the service area size for each relay node, it is important to use the location information of other neighboring nodes and their service area sizes. However, in general, such information is completely unknown or only partially known. In the present paper, we introduce three methods to determine the service area size, each of which assumes a different level of the knowledge regarding neighboring nodes. We conduct extensive simulation experiments to evaluate the performance of these three methods in terms of coverage ratio, service area overlap characteristics, energy consumption, and utilization efficiency of wireless network resources. We confirm the trade-off relationships between the knowledge level and performance for these three methods.
