Abstract: Most of the sensor nodes in Wireless Sensor Network (WSN) are powered by batteries, therefore the lifetime of the sensor nodes are fully relying on its power efficiency. In addition to that, the wireless sensor nodes are commonly placed, distributed and installed in the place where difficult to reach, thus it becomes inconvenient especially when replacing the batteries and leads to high maintenance cost. Due to this reason, batteries and energy source of the sensor nodes has been replaced with more sustainable energy source such as energy harvested source. However, due to some reasons, especially in dense network environment, the energy harvested WSN performs poorly and its network performance is not optimized enough. One of the factors that lead to the low performance of energy harvested WSN is the placement and location of sensor nodes in the network, its network configuration (i.e. single-hop and multi-hops) and the number of sensor nodes used. Therefore, in this study, we investigated and studied the performance of energy harvested WSN in different configuration such as single-hop and multi-hops and in terms of its transmission time (delay), power efficiency, and throughput. The real time energy harvested WSN is deployed for the purpose measurement and analysis.
