Abstract: Limited lifetime of batteries is a major constraint in Wireless Sensor Networks (WSNs). Reduction in duty cycle to conserve energy resulted in reduced throughput. With the advances in energy harvesting technologies there is considerable research interest in enhancing the performance of WSNs by incorporating the energy harvesting scenario in wireless nodes. To ensure proper operation of the sensor nodes in WSNs with energy harvesting, the design of MAC protocols need special consideration. This paper evaluates the performance of an energy harvesting WSN node, based on IEEE 802.15.4 MAC. The study establishes the fact that by suitably adapting the duty cycle, throughput of the node can be increased in addition to extending its lifetime considerably.
