Abstract
Energy efficiency and data reliability are stringent requirements for today’s IoT networks. In order to achieve energy efficiency transmission power and energy level of the node during data transmission should be optimized. There is a trade-off between energy efficiency and the reliability of received data. Cross-Layer based Energy Efficient Reliable Data Transmission System (CLEERDTS) for IoT Networks is proposed in this research work such that energy consumption is minimized and reliable data delivery is achieved. In this proposed cross-layer model, the location information of nodes is embedded in the network layer, transmit power is estimated at Media Access Control (MAC) layer and thereafter transmission mode is decided at the physical layer. During route discovery, when the sender receives the Route Reply packet, it estimates the SNR value and selects the route which utilizes minimum transmit power and higher SNR. If no such route exists, it selects candidate relay nodes between the sender and Base station (BS) such that the residual energy of the relay node is highest among possible candidates. Simulation results show that the proposed CLEERDTS model offers better performance as compared to the existing model in terms of energy consumption, packet delivery ratio, packet error rate and throughput.
