Localization Error Estimation in WSNs: A comparative case study

Smart environments represent the next evolutionary development step in building, utilities, industrial, home, shipboard, and transportation systems automation. Like any sentient organism, the smart environment relies first and foremost on sensory data from the real world. Sensory data comes from multiple sensors of different modalities in distributed locations. Wireless Sensor Networks (WSNs) consist of sensor nodes that broadcast a message within a network. Efficient broadcasting is a key requirement in sensor networks and has been a focal point of research over the last few years. There are many challenging tasks in the network, including redundancy control, average localization error, sensor node localization that decides the reliability of network. Efficient sensor node localization algorithm is a research highlight in the applications of WSNs. An event information with few node location information is meaningless in practical application so localization become a important point of concern. In this paper, we propose a comparative study of the two localization algorithm high-resolution range-independent localization (HiRLoc) and secure robust localization (SeRLoc). The comparison is done by using dual antenna.
