Cross Layered MAC Design for RF Energy Harvesting Sensor Network

引用

Circuits and Systems 2016年第9期7卷 2676-2688页

作者： Thangavelu Sasikala Veerasamy Jawahar Senthil Kumar Department of ECE College of Engineering Anna University Chennai India

The main research objective in wireless sensor networks (WSN) domain is to develop algorithms and protocols to ensure minimal energy consumption with maximum network lifetime. In this paper, we propose a novel design for energy harvesting sensor node and cross-layered MAC protocol using three adjacent layers (Physical, MAC and Network) to economize energy for WSN. The basic idea behind our protocol is to re-energize the neighboring nodes using the radio frequency (RF) energy transmitted by the active nodes. This can be achieved by designing new energy harvesting sensor node and redesigning the MAC protocol. The results show that the proposed cross layer CL_EHSN improves the life time of the WSN by 40%.
