One of key challenges in deploying large-scale Wireless Sensor Network (WSN) is system longevity. In this paper, the authors propose a harvesting aware system of SMSN (Sustainable Mobile Sensor Network) as a way to extend system lifetime. The mobile sensor nodes visit remote energy station to recharge battery when node's energy drains below a threshold level. Their framework consists of energy model, motion control system and data transfer protocol. The simulation result shows the sustainability of their SMSN. Their results along with simulation can be used for certain guideline for realistic development of such systems.
