ABSTRACT: 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%.
