Distributed Policy-Based Management for Wireless Sensor Networks

Security and blockchain convergence with Internet of Multimedia Things: Current trends, research challenges and future directions

“…, a policy is defined for the system or network behavior. Policy works similar to a constraint expressed using natural language or mathematical notation [107]. Policy is a set of rules for trust evaluation.…”

“…Alternatively, the data centers may only query those relay nodes that have satisfied a pre-defined trust-level for accessing some critical data gathered by the surveillance cameras. The existing policy-based approaches [108,109,107,110] have higher adaptability, accuracy and reliability. However, most of them do not consider the heterogeneity of the devices.…”

Enabling smart environments through scalable policy reasoning and Internet of Things

“…There is a variety of policy frameworks: some with rich policy representations (Kagal, Finin, & Joshi, ; Sensoy, Norman, Vasconcelos, & Sycara, ; Uszok et al, ), and some targeting pervasive environments (Qwasmi & Liscano, ; Twidle, Dulay, Lupu, & Sloman, ; Zhu, Keoh, Sloman, & Lupu, ). However, they are either not scalable—e.g., to create and refine policy instances to large number of devices (Sensoy et al, )—or expressive enough to use high level concepts to describe devices and situations (Twidle et al, ).…”
