ABSTRACT
Wireless transmission is one of the most energy consuming tasks in nowadays communicating devices and the Internet of Things in general. This generates huge amount of dangerous and harmful waste for nature such as batteries. Therefore, reducing wireless transmissions has been one of the most investigated levers to optimize energy consumption in the Internet of Things and hence design more nature-friendly IT landscape. However, few of those works considered the impact of temperature and other environmental factors on the quality of radio transmission and leverage that impact to improve network lifetime through optimized energy usage. In this work, we design a new routing protocol that takes into consideration temperature impact on the quality of transmissions. Indeed, many studies showed that high temperatures negatively influence the quality of transmissions which requires higher transmission powers and hence more energy consumption and rapid battery depletion. We consider Delay Tolerant Networks and leverage atmosphere temperature sensing of devices to decide when and where to send data in an energy-effective way. We show, through simulations, that our approach allows to improve energy consumption at the cost of extra-latency that should not harm applications running over Delay-Tolerant Networks.
