This paper proposes a new fault-tolerant sensor network architecture for monitoring pipeline infrastructures. This architecture is an integrated wired and wireless network. The wired part of the network is considered the primary network while the wireless part is used as a backup among sensor nodes when there is any failure in the wired network. This architecture solves the current reliability issues...
Environmental monitoring in agriculture is an interesting and promising area of application for wireless sensor networks. Wireless sensor networks can deliver valuable information about environment, animals and their habitat. This paper describes a case where such sensing application was implemented with biologists. The wireless sensor network collected data in hard outdoors conditions over a period...
The expected lifetime of any wireless sensor network is a critical issue as sensor nodes are powered by small batteries. One effective approach for energy conservation, especially in high density networks, consists on switching alternatively nodes in sleep/active modes, while ensuring at the same time continuous monitoring (i.e., coverage and connectivity). In this paper we propose a novel approach...
Body sensor networks are an interesting emerging application of wireless sensor networks to improve healthcare and the quality of life. Current research has mainly focused on single-hop networks, although some works clearly show advantages of multi-hop architectures. In this paper, we model probabilistic connectivity in such multi-hop body sensor networks. Instead of using a circular coverage area,...
