Sensor networks: an overview
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:
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

Reliable and energy-efficient data collection in wireless sensor networks
TL;DR: This thesis proposes to use relay nodes for traffic relaying and suggests that the deployment should be aware of the data traffic to be collected by specific applications, and discusses how to efficiently disseminate message in a low duty-cycle scenario, where nodes alternate between active and dormant states to conserve energy and thus extend the network lifetime.
