Abstract. We are developing a decentralized approach to trust based on referral systems, where agents adaptively give referrals to one another to find other trustworthy agents. In...
Different applications have different security requirements for data privacy, data integrity, and authentication. Encryption is one technique that addresses these requirements. En...
Abstract— In this paper, we propose an incentive system to stimulate the nodes’ cooperation in multi-hop wireless networks. Reducing the number and the size of the payment rece...
Abstract--Cognitive radio networks require fast and reliable spectrum sensing to achieve high network utilization by secondary users. Current optimization approaches to spectrum se...
