Location estimation system using wireless ad-hoc network

Location aware computing is popular and location information has become more important before. Ubiquitous computing also needs location information. We propose a location estimation system using a multi-hop wireless ad-hoc network. The proposed system estimates the locations of mobile hosts, using distance between hosts and the locations of some special hosts which know each location by GPS or other devices. This system is designed as a client-server model. The server is called an accumulator host and calculates the locations of all hosts. We also describe an estimation algorithm running in the accumulator host.
