Lately, there has been significant progress in the field of wireless communications and networking. Furthermore, the number of applications that require context information as the user's location will increase in the coming years. However, this issue still has not been solved indoors due to the RF (Radio Frequency) signals' behaviour in this kind of scenarios. In this paper, we present a robust, easy...
Trust and reputation models research and development for distributed systems such as P2P networks, wireless sensor networks (WSNs) or multi-agent systems has arisen and taken importance in the last recent years among the international research community. However it is not always easy to check the correctness and accuracy of a model and even more, to compare it against other trust and reputation models...
The energy-constrained wireless sensor nodes require the designs of energy-efficient content authentication protocols. In this paper, we combine the approaches of cryptography and content analysis to propose a new light-weight content authentication framework Cobra. In Cobra, only a small fraction of transmitted packets are protected with signatures. The unprotected packets are authenticated using...
