Delay Tolerant Mobile Sensor Network (DTMSN) is the network for pervasive information gathering. Traditional data information gathering approaches may not fit for DTMSN for its intermittent connectivity. This paper proposes an Activity Based Data gathering protocol (ABD). In DTMSN, activity of different sensors may vary since they are attached to different entities, the message replicated by the active...
With the development of sensor, wireless mobile communication, embedded system and cloud computing, the technologies of Internet of Things have been widely used in logistics, Smart Meter, public security, intelligent building and so on. Because of its huge market prospects, Internet of Things has been paid close attention by several governments all over the world, which is regarded as the third wave...
The “Internet of Things” infrastructure will be strongly integrated with the environment, and its integration with the enterprise systems will not only further blur the line between business IT systems and the real world. To contribute to the secure development of IOT, the research mainly focuses on the key trust control technologies in IOT, including heterogeneous network model, trust routing, and...
Nodes localization in mobile sensor networks can be dealt as a problem of mobile object tracking. The particle filters algorithm which is based on Bayesian estimation and Monte Carlo method is an effective tool to deal with these problems. The particle filters algorithm adopts a series of weighted particles to represent the possible position of a mobile object, and then makes use of the present observation...
