TLDR
A sensor network can provide access to information anytime, anywhere by collecting, processing, analyzing and disseminating data, and actively participates in creating a smart environment.Abstract:Â
Advances in hardware and wireless network technologies have created low-cost, low-power, multifunctional miniature sensor devices. These devices make up hundreds or thousands of ad hoc tiny sensor nodes spread across a geographical area. These sensor nodes collaborate among themselves to establish a sensing network. A sensor network can provide access to information anytime, anywhere by collecting, processing, analyzing and disseminating data. Thus, the network actively participates in creating a smart environment.read more
