ABSTRACT To solve the secure localization problems, a number of secure localization schemes have been developed at present. However, most of these techniques cannot survive collusion attacks where a majority of malicious nodes launch colluding attacks. In this paper, we introduce a new collusion attack model called Collaborative Collusion Attack Model (CCAM) and propose a novel scheme called Two-Step Format Detection (TSFD) that is well suited to WSN which is a resource constrained environment. The TSFD has reasonable and acceptable communication cost and algorithm complexity. Through simulations, we compare the performance of TSFD with other secure localization schemes and show that TSFD has more efficient and resilient performance.

    ABSTRACT: Ad hoc wireless sensor networks (WSNs) have attracted a great deal of attention in recent years for their broad potential in both military and civilian operations. The proper operations of many WSNs rely on the knowledge of physical sensor locations. However, most existing localization algorithms developed for WSNs are vulnerable to attacks in hostile environments. As a result, adversaries can easily subvert the normal functionalities of location-dependent WSNs by exploiting the weakness of localization algorithms. In this paper, we first present a general secure localization scheme to protect localization from adversarial attacks. We then propose a mobility-assisted secure localization framework for WSNs.
