| Abstract: | With the development of the wireless sensor networks,city-wide deployments begin to emerge.However,its charac-teristics,such as large scale,low cost,mobility and sparse topology,bring difficulties and challenges to the localization methods.In this paper,a GPS-free cooperative localization algorithm is proposed,as a solution to the localization demands for typical metropolitan area wireless sensor networks,it takes advantage of the Manhattan Torus probabilistic mobility model.The convergence and stability co... |
