%0 Journal Article %T DESIGN AND IMPLEMENTATION OF A TRUST-AWARE ROUTING PROTOCOL FOR LARGE WSNS %A Theodore Zahariadis %A Helen Leligou %A Panagiotis Karkazis %A Panagiotis Trakadas %J International Journal of Network Security & Its Applications %D 2010 %I Academy & Industry Research Collaboration Center (AIRCC) %X The domain of Wireless Sensor Networks (WSNs) applications is increasing widely over the last few years.As this new type of networking is characterized by severely constrained node resources, limited networkresources and the requirement to operate in an ad hoc manner, implementing security functionality toprotect against adversary nodes becomes a challenging task. In this paper, we present a trust-aware,location-based routing protocol which protects the WSN against routing attacks, and also supportslarge-scale WSNs deployments. The proposed solution has been shown to efficiently detect and avoidmalicious nodes and has been implemented in state-of-the-art sensor nodes for a real-life test-bed. Thiswork focuses on the assessment of the implementation cost and on the lessons learned through the design,implementation and validation process. %K Wireless sensor networks %K trust management %K secure routing %K implementation cost %U http://airccse.org/journal/nsa/0710ijnsa04.pdf
