Applications of Engineering Technology and Science (AETS)
The information of sensors' locations is crucial data in Wireless Sensing element Networks (WSNs). When sensing nodes are deployed in hostile environments, the localization schemes are susceptible to numerous attacks, e.g., wormhole attack, pollution attack, collusion attack, etc. Therefore, sensors' locations aren't trustworthy and wish to be verified before they will be employed by location-based applications. Previous verification schemes rely upon expensive or dedicated hardware, so they can't be used for affordable sensing element networks. In this paper, the authors tend to propose a lightweight algorithms that performs location verifications.
