Title: Sensors with Lasers: Building a WSN Power Grid

Abstract

We present here a first practical energy distribution architecture that allows us to decouple energy supply from sensing activities in WSN. Such a separation of responsibilities enables us to utilize abundant energy sources distant from the sensing location, allowing unrestricted lifetime and resolving unequal energy consumption in WSN. We demonstrate energy transfer for practical decoupling using low-cost and -footprint, laser µ-power beaming that powers current WSN platforms at 100m of range. We design and implement LAMP: a tiered architecture to manage energy supply to both mesh and clustered WSN deployments using an energy distribution protocol. We evaluate our system to show that, for an additional cost of $29 per mote, LAMP can support perpetual mesh functionality for up to 40 sensors or 120 nodes in clustered operation.

Bio

Since January 2013 <link http: web.lums.edu.pk>Hamad is an Assistant Professor at the Department of Computer Systems Engineering, UET Peshawar, Pakistan, where he also heads EmNets lab. Previously, he was a Research Assistant at <link http: www.comsys.rwth-aachen.de _blank>COMSYS, RWTH Aachen University, Germany. He received his PhD and MSc Degrees from RWTH Aachen University in 2012 and 2007, respectively. His research interests are in mobile applications, Internet of thing and sensornets. He is particularly interested in applications, protocols, architectures, and evaluation tools for future networks.
