TY - JOUR ID - citeulike:2282840 L3 - citeulike-article-id:2282840 N2 - Accurate and low-cost sensor localization is a critical requirement for the deployment of wireless sensor networks in a wide variety of applications. In cooperative localization, sensors work together in a peer-to-peer manner to make measurements and then forms a map of the network.
