Radio Signal Based Device-Free Velocity Recognition,uire the Line-of-Sight signal which limits the application in the Non-Line-of-Sight (NLOS) environment. More importantly, how to distinguish the velocity of human is still an open problem. In this paper, we present an approach for device-free velocity recognition leveraging the radio-frequency (RF)

Minimum-Cost Information Dissemination in Social Networks,ng community. In this paper, we consider the problem of finding the minimum set of initial users of a topic to propagate a message so that, with a given guaranteed probability, the number of users discussing the topic would reach the critical threshold. This study is formally called the . (.) proble

Computing an Optimal Path with the Minimum Number of Distinct Sensors,present a method to compute a path crossing the minimum number of distinct sensors from a source to a destination.Then, we propose the selfish path problem, in which the intruder is always getting more closer to the destination, and we design a greedy algorithm for this problem. We implement these a

ULRAS: Ultra-Lightweight RFID Authentication Scheme for Mobile Device,ding. However, the widespread use of RFID tags brings the possibility for various security risks and privacy problems. In addition, the storage space, processing capability and power supply of RFID tags are limited. In this paper, in order to reduce the computational cost we present an ultra-lightwe

Impact of a Deterministic Delay in the DCA Protocol,e normal DCF procedure, so that more packets can be backlogged and transmitted upon each transmission opportunity. Therefore, DCA is of great practical importance in improving channel utilization. However, how the extra delay affects the performance of DCA has never been theoretically investigated.

EBRS: Event Based Reputation System for Defensing Multi-source Sybil Attacks in VANET,cular accidents in vehicular ad hoc network (VANET). It is very difficult to be defended and detected, especially when it is launched by some conspired attackers using their legitimate identities. In this paper, we propose an event based reputation system(EBRS), in which dynamic reputation and trust
