Challenges in mobile localisation in wireless sensor networks for disaster scenarios

In disaster scenarios, dynamic sensors are often used for localisation in wireless sensor networks (WSNs). However, most of the existing localisation algorithms are designed for the static nodes in WSNs. This paper presents a survey of localisation algorithms in mobile wireless sensor networks (MWSNs): robotics localisation algorithms, Monte Carlo based mobile localisation algorithms and range-free based mobile localisations. A comparison of the state-of-the art mobile localisation algorithms is conducted in this paper.
