To cope with challenging communication conditions in VANETs where connectivity is intermittent, and the quality of wireless channel is unstable and communication links are easily broken, we present an improved infrastructure assistant vehicle-to-passenger (V2P) protocol was proposed. The proposed protocol can reach very high query efficiency and matching accuracy with low delivery delay and communication...
Wireless sensor network (WSN) applied on bridge health monitoring has attracted considerable attention for its advantages such as self-organization, micro-structure, low cost and high flexibility. The performances of WSNs are extremely correlated with application scenarios and even the same protocol may results in an obvious performance difference on various applications. However, no one has studied...
Due to the limitation of the energy, the performances and applications were constrained of the pure batteries powered wireless sensor networks (WSNs). WSNs with energy harvesting extracting energy from the surrounding environment, supplement energy to the sensor nodes, can be significant prolong the lifespan of WSNs, or even make WSNs running for perpetual. In order to determine the node energy harvesting...
