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...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
