Traffic Balancing Network Architecture for Enhancing Lifetime of Smart Devices in Low Power Internet of Things Networks

The aim of our study is to integrate the features of node placement technique and routing technique in single network architecture to enhance the lifetime of low power IoT Networks. The Internet of Things (IoT) is smart technology that converges smart devices with global network infrastructure and promotes effective resource utilization. Smart devices are considered as key element in low power IoT networks (energy constrained IoT network infrastructure). The phrase "low power" refers the battery sourced IoT devices and low power radio links (IEEE 802.15.4). Enhancing the lifetime of smart devices by balanced energy utilization is the major goal in low power IoT networks. Thus, we propose energy efficient and reliable network architecture by integrating the features of node placement technique and routing technique. In proposed network architecture, traffic load is concentrated, since traffic load decidedly influence the energy efficiency and reliability of the network. In node placement technique, transmission ranges of nodes are varied based on data traffic, which assures balanced energy utilization and maintains network connectivity. Traffic load information is added in routing process, to achieve reliable data transfer and to balance energy utilization. Thus, effective integration of routing technique and node placement technique in single network architecture highly promotes the network lifetime with better reliability. The idea at the heels of our work is integrating features of two optimization techniques in single network architecture will satisfy specific network requirements. From our results, it is observed that the proposed network architecture prolongs the network lifetime and maintains reliable data transfer.
