| Popis: | Energy conservation is the main major issue in wireless sensor networks (WSNs). Indeed, recharging energy sources in WSNs is often too costly, difficult and sometimes impossible. To extend the WSN lifetime without recharging, energy saving methods and energy harvesting systems are crucial. In this paper, we propose Enhanced Energy Management Scheme in Energy Harvesting Wireless Sensor Networks (EEM-EHWSN). EEM-EHWSN uses receiver-initiated communication that regulates the active/sleep periods through the introduction of an energy threshold policy and use of remaining energy in order to decrease the duty-cycle while ensuring a balance between the energy consumption and energy harvesting ability by each sensor node in the WSN. The EEM-EHWSN was implemented using OMNeT++/MiXiM, and the simulation results show that our scheme improves the overall performance of the network through reducing the mean latency, increasing the throughput and the packet delivery ratio. |
