MEGA: An energy aware algorithm for self-powered wireless sensor networks in sustainable smart infrastructure
Qi Dong, Yu Chen, Shahrzad Towfighian · 2014
Smart infrastructure is attractive for many desirable features. Embedded sensors that collect information are critical for decision making. However, the lifetime of electronic sensors is a constraint to infrastructure lifetime if sensors are physically embedded in the infrastructure at construction time. In this paper, we studied a self-powered wireless sensor network that harvests energy from mechanical vibration in the environment. A dynamic, hierarchical algorithm called MEGA is proposed that constructs clusters and elects the cluster head based on residue energy and energy harvest rate. Taking a smart bridge as an application example, the simulation study has verified the effectiveness of the proposed protocol.
