A hybrid data aggregation scheme for Internet of Things (IoT)

Internet of Things (IoT) is an indispensable part of future Internet. It is gaining tremendous popularity among research and industrial communities. Wireless sensor network (WSN) is a major constituent of IoT. To reduce power consumption of devices and hence to increase network lifetime, data aggregation schemes are highly used in WSN. In this paper, an efficient hybrid data aggregation scheme adapting to the architecture of IoT is proposed. The proposed hybrid approach is placed in between the cluster and tree-based data aggregation schemes addressing the limitations of both the types. It shows clear improvement over LEACH, LEACH-C and TREEPSI protocols in terms of power consumption, network lifetime and traffic load.
