Cooperative Localization in Wireless Ad Hoc and Sensor Networks

The need for highly accurate position information is of great importance in many commercial, public safety, and military applications.With the integration of GPS into cell phones, in conjunction withWiFi localization, we are entering a new era of ubiquitous location-awareness. In the coming years, we will see the emergence of high-definition location-awareness applications: localization systems that operate in the harsh communication environments where GPS does not operate, such as inside buildings and in caves, still providing submeter localization accuracy which is not currently feasible with GPS.
