1. A wireless sensor node for a mesh network, the sensor node comprising:
an antenna layer operative to receive and transmit wirelessly, wherein the antenna layer includes a metamaterial surface;
a sensing layer including a fractal surface, operative to detect data from one or more sensors;
an energy harvesting layer operative to harvest energy from an environment local to the sensor node;
a reception/transmission layer;
a processing layer operative to process data from the sensing layer and signals received from or provided to the reception transmission layer; and
a power storage layer operative to store energy received from the energy harvesting layer for use by the sensor node, wherein the antenna layer includes one or more fractals.
