Securing the Information in Social Media with STB Routing Protocol

With the proliferation of fairly powerful mobile devices and ubiquitous wireless technology, traditional mobile ad hoc networks (MANETs) now migrate into a new era of service-oriented MANETs where in a node can provide and receive service from other nodes it encounters and interacts with. This proposed research concerns trust management and its applications for service-oriented. MANETs to answer the challenges of MANET environments, including no centralized authority, dynamically changing topology, limited bandwidth and battery power, limited observations, unreliable communication, and the presence of malicious nodes who act to break the system functionality as well as selfish nodes who act to maximize their own gain. A context-aware trust management model called secure trust based (STB) routing protocol for service-oriented ad hoc networks is proposed in the proposed system. The novelty of the design lies in the use of trust calculation to dynamically estimate trustworthiness of a service provider based on its service behavior patterns in a context environment, treating channel conditions, node status, service payoff, and social disposition as “context� information. This develops a recommendation filtering mechanism to effectively screen out false recommendations even in extremely hostile environments in which the majority recommenders are malicious. This demonstrated desirable convergence, accuracy, and resiliency properties of STB.
