Monte-Carlo Localization for Mobile Wireless Sensor Networks
Localization is crucial to many applications in wireless sensor networks. This article presents a range-free anchor-based localization algorithm for mobile wireless sensor networks that builds upon the Monte Carlo Localization algorithm. We improve the localization accuracy and efficiency by making better use of the information a sensor node gathers and by drawing the necessary location samples...
متن کاملPrecision Localization in Monte Carlo Sensor Networks
We have proposed Monte Carlo Sensor Networks as a method to solve certain sensor queries in the presence of noise and partial information. In that work we used very coarse position estimates for enemy agents. Here we propose methods to (1) improve the posterior probability estimates by using a more precise analysis of the sensor range geometry, and (2) help select advantageous locations to plac...
متن کاملApplied Sensor-Assisted Monte Carlo Localization for Mobile Wireless Sensor Networks
Localization is a mandatory requirement in almost all sensor network applications. In order to avoid power-hungry GNSS solutions like GPS, alternative localization algorithms based on anchor nodes are developed. Unfortunately, many proposed solutions focus on static networks and do not account for mobility. An often cited and further improved approach is Monte Carlo Localization (MCL), which is...
متن کاملLocalization in mobile sensor networks: A research on Sequential Monte Carlo localization
Much research is done at the localization of sensor nodes in a static wireless sensor network. In this paper, the focus is only on the localization of nodes in mobile sensor networks. An algorithm is proposed for mobile sensor networks that use all available information to get better location estimates. Our goal for this algorithm was to minimize communication costs, to have a stable performanc...
متن کاملWormhole Attack Detection in Wireless Sensor Networks
The nature of wireless ad hoc and sensor networks make them very attractive to attackers. One of the most popular and serious attacks in wireless ad hoc networks is wormhole attack and most proposed protocols to defend against this attack used positioning devices, synchronized clocks, or directional antennas. This paper analyzes the nature of wormhole attack and existing methods of defending me...
