Recent breakthroughs in wireless technologies have greatly spurred the emergence of industrial wireless sensor networks (IWSNs). To facilitate the adaptation of IWSNs to industrial applications, concerns about networks’ full coverage and connectivity must be addressed to fulfill reliability and real-time requirements. Although connected target coverage (CTC) algorithms in general sensor networks have...
The energy efficiency is critical for application of wireless sensor networks, since it is a main precondition for their long-live functionality, small modification costs and reliability. This paper deals with the placement of wireless nodes based on the modeling of radio wave propagation. The methods are realized in a planning tool CANDY Wireless Site Finder that provides optimized topologies of...
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...
