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...
