In order to make up for deficiencies in the current mine-security monitoring system, the paper proposes a mine-security real-time monitoring system based on 6LoWPAN. In the system, WSN achieves the direct access to the internet and does not need a specific gateway to fulfil the protocol conversion or the protocol bearing, and in the meanwhile WSN achieves the end-to-end communication with the Internet...
Unattended Wireless Sensor Networks (UWSNs) are networks that operate without on-line data collection entities (Sink Collectors). This configuration enriches their flexibility but, at the same time, introduces new security issues. A challenging issue is data survival: in absence of the sink, in fact, data sensed by network sensors cannot be kept clear from the adversary. Cryptographic schemes, moreover,...
In this paper, we propose a secure embedded gateway system for a wireless sensor network that provides secure wireless and wire communication channels for wireless sensor nodes and applications in the Internet, respectively. It also has security functions such as key management, access control and secure wireless network configuration for wireless sensor nodes and secure query process for its applications...
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
