Network connectivity of layered self-organizing wireless networks

This paper proposes a new organizing method for packet radio networks: layered self-organizing method. In the layered self-organizing network, a whole service area is divided into multiple sub-service areas and one base station is settled in each sub-service area. Base stations are connected to the backbone network, a high-speed wired network. A base station covering area is tuned to be less than a sub-service area. Mobile stations that stay in the outside area of a base station covering area are connected with one of the near base stations through several repeating mobile stations in a self-organized fashion. So a layered self-organizing wireless network can cover a wide area with fewer base stations than the conventional cellular networks. This paper evaluates the network connectivity by computer simulation and shows the effectiveness of the method. Furthermore, the paper presents an additional power-control protocol to obtain almost complete connectivity in the whole network
