Sensors with lasers: Building a WSN power grid

We present here a first prac architecture that allows us to decouple en activities in WSN. Such a separation of us to utilize abundant energy sources d location, allowing unrestricted lifetime energy consumption in WSN. We demons practical decoupling using low-cost and -beaming that powers current WSN platf We design and implement LAMP: a tiered energy supply to both mesh and clust using an energy distribution protocol. W show that, for an additional cost of $2 support perpetual mesh functionality for nodes in clustered operation.
