In this paper we consider security-related and energy-efficiency issues in multi-hop wireless networks. We start our work from the observation, known in the literature, that shortest path routing creates congested areas in multi- hop wireless networks. These areas are critical-they generate both security and energy efficiency issues. We attack these problems and set out routing in outer space, a new...
Wireless sensor networks (WSN) are expected to form an integral part of the foreseen ubiquity intelligent, future mobile network and are envisaged to play a key role in the vision of offering mobile, personalised services, in-home and out-doors, whenever and wherever needed. However, security and resilience across WSN, especially across insecure, heterogeneous and multi-administration domains like...
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...
