Although these types of algorithm are vulnerable to several types of security attack, less work has been done to implement secure localisation algorithms that are able to work in a hostile environment. An attacker could compromise, or masquerade as, a beacon node and send incorrect location information. Localisation in a hostile environment is a critical problem in wireless sensor networks (WSNs) because compromising the localisation system could disturb and subvert the entire functioning of the WSN. In this paper we investigate the security of recently proposed localisation algorithm, called ALWadHA, which enables nodes to live with the malicious reference nodes without disturbing the location estimation.enWireless Sensor NetworksALWadHAMalicious nodesSecure localisationConference PresentationAbu-Mahfouz, A.
