ActiSen: Activity-Aware Sensor Network in Smart Environments
A sensor network, unlike a traditional communication network, provides high degree of visibility into environmental physical processes. Therefore, its operation is driven by the activities in the environment. In long-term operations, these activities usually show certain patterns which can be learned and utilized to optimize network design. However, this has been almost unexplored in the literature. In this paper, the authors present the design and validation of ActiSen system, an activity-aware sensor network in smart environments. ActiSen consists of three components: activity-aware sensing, activity-aware radio duty-cycling, and activity-aware and energy balanced routing.
