Given the wide range deployment of disconnected delay-tolerant social Internet of Things (SIoT), efficient resource discovery remains a fundamental challenge for large-scale SIoT. The existing search mechanisms over the SIoT do not consider preference similarity and are designed in Cartesian coordinates without sufficient consideration of real-world network deployment environments. In this paper,...
Given the resource consumption of transmitting data packets in Vehicular Ad Hoc Network (VANET), selfish nodes might refuse to transmit messages to others just for maximizing their own profits. Therefore, the communication performance within the whole network would be affected. Along with its wide-scale implementation in many road-side applications, selfish behaviors of such nodes are witnessed to...
Mobile P2P (MP2P) networks is open and complex, and hence secure communication is a challenging issue for MP2P applications. Peers in the dynamic networks sometimes can obtain each other's trust and risk data, sometime or not. Nowadays, researchers can only study one for the two different scenarios, and thus the existing schemes are not universal and integrity. In this paper, we use the historical...
