Probabilistic Cooperative Location Estimation in Wireless Networks

摘要: Applications of location estimation have drawn lots interests in recent years. Many schemes been developed to estimate the locations concerned users. Conventionally, each user is estimated independently by its own observations from local environment. In this paper, we propose a cooperative scheme. From encounter history specific meeting other users and results users, able further improve accuracy estimation. Simulation show that algorithm provides significant gain over non-cooperative scheme increases with number involved cooperation.
