An event-triggered localization algorithm for mobile wireless sensor networks

Many localization algorithms have been proposed for wireless sensor network. They focus on localization for static sensor network, but not for mobile one. With the development of sensor and network technology, a wireless sensor network with mobile sensor nodes becomes applicable. A mobile wireless sensor network (MWSN) consists of sensor nodes that may move often. Traditional localization algorithms for static sensor networks are not suitable to MWSN. MWSN applications demand new localization algorithms. In this paper, we propose an event-triggered localization algorithm which is based on RF (radio frequency) fingerprint and RSSI (received signal strength indicator) techniques. It is a distributed and low-cost localization algorithm with high accuracy. The simulations show that our proposed localization algorithm has better performance.
