Relaying data with the help of mobile elements seems an effective way to bridge the gaps in sparse sensor networks. In this paper, we propose the Voronoi-diagram-based mobile element scheduling (VDMES) algorithm to construct the shortest possible path for mobile elements. The mobile elements are scheduled to visit a small subset of Voronoi vertices rather than the sensor nodes, which is carefully...
Static always-on wireless sensor networks (WSNs) are affected by the energy sink-hole problem, where sensors nearer a central gathering node, called the sink, suffer from significant depletion of their battery power (or energy). It has been shown through analysis and simulation that it is impossible to guarantee uniform energy depletion of all the sensors in static uniformly distributed always-on...
The design process of protocols for wireless sensor networks (WSNs) is primarily concerned with tackling special issues inherent to WSNs, such as limited energy (or battery power), computation, communication, and storage capabilities, with energy being the most crucial resource for sensor nodes. This paper proposes LAMaR, a location-aided and maximum remaining energy-based data dissemination protocol...
