Green Data Gathering under Delay Differentiated Services Constraint for Internet of Things

Energy-efficient data gathering techniques play a crucial role in promoting the development of smart portable devices as well as smart sensor devices based Internet of Things (IoT). For data gathering, different applications require different delay constraints; therefore, a delay Differentiated Services based Data Routing (DSDR) scheme is creatively proposed to improve the delay differentiated services constraint that is missed from previous data gathering studies. The DSDR scheme has three advantages: first, DSDR greatly reduces transmission delay by establishing energy-efficient routing paths (E2RPs). Multiple E2RPs are established in different locations of the network to forward data, and the duty cycles of nodes on E2RPs are increased to 1, so the data is forwarded by E2RPs without the existence of sleeping delay, which greatly reduces transmission latency. Secondly, DSDR intelligently chooses transmission method according to data urgency: the direct-forwarding strategy is adopted for delay-sensitive data to ensure minimum end-to-end delay, while wait-forwarding method is adopted for delay-tolerant data to perform data fusion for reducing energy consumption. Finally, DSDR make full use of the residual energy and improve the effective energy utilization. The E2RPs are built in the region with adequate residual energy and they are periodically rotated to equalize the energy consumption of the network. A comprehensive performance analysis demonstrates that the DSDR scheme has obvious advantages in improving network performance compared to previous studies: it reduces transmission latency of delay-sensitive data by 44.31%, reduces transmission latency of delay-tolerant data by 25.65%, and improves network energy utilization by 30.61%, while also guaranteeing the network lifetime is not lower than previous studies

GREEN RADIO COMMUNICATIONS IN 5G NETWORKS TO IMPROVE ENERGY EFFICIENCY AND REDUCE GLOBAL WARMING

The technology of green radio communication helps in reducing the emission of carbon and also helps in the process of reducing the consumption of energy by the base stations of wireless networks. In addition to that, with the help of tools such as Information Communication Technology (ICT) and Multi-Hop Relay Network (MHR), the functionalities and the operational attributes of the technology of green radio communication can be improved and the process of energy consumption gets better as well. It is found from the discussion that green networking technology has mainly two core components and the two core components are energy awareness and energy efficiency. The ability of the network to measure the cost per packet is called energy awareness. On the other hand, the ability of a network to decrease the contribution of carbon and extend the lifetime of the network can be called energy efficiency. In addition, the implementation of the technology of green radio communication helps in mitigating the issue of future energy crises. Additionally, it has also been understood that Green communication in terms of energy efficiency can help IT industry which has been extensively criticised for the contribution of the carbon emissions as well as the failure to respond to the negative impact on the whole climate. In fact, the next generation networks have imposed the challenges in terms of the provision of the energy efficient solutions which are provided and the transportation of the data along with the huge range of the quality of the services requirement as well as the tolerance of lower optimum services.The technology of green radio communication helps in reducing the emission of carbon and also helps in the process of reducing the consumption of energy by the base stations of wireless networks.
