Abstract
Internets of Things (IoT) devices rely on self-powered energy sources for communication and information exchange. The functions of the devices rely on the available energy for which, conservation of energy expenses becomes necessary. This aids to retain the lifetime of the communicating devices and to augment the seamlessness of information exchange. This article introduces transmission adaptive mode selection (TAMS) for conserving the energy expenses of the IoT devices. Cross-layer design defines the communication modes for the devices depending on the physical attributes associated with the transmission. This transmission mode of the device is adaptive depending on the communication environment, distance and energy efficiency factors. In particular, congestion and residual energy are used for identifying the appropriate transmission mode, in a view to maximize energy conservation. This method reduces the communication delay and improves the transmission rate along with the balanced energy consumption.
