A Green Routing Protocol with Wireless Power Transfer for Internet of Things

The usually constrained resources and lossy links scenarios of Internet Things (IoT) applications require specific protocol suite, as the IPv6 Routing Protocol for Low-Power Lossy Networks (RPL). Due to its flexibility, RPL can support efficiently vertical such environmental monitoring, smart city Industry 4.0. In this paper, we propose a new Objective Function (OF) based on composite metric considering jointly residual energy node (parent) together with that neighbor (child) transfer parent according Wireless Power Transfer (WPT) concept. Specifically, consider simultaneous wireless information power (SWIPT) technique, which enables both harvesting decoding from same radio frequency (RF) signal, in order influence selection best path proposed efficient RPL. Performance evaluation realistic scenario pointed out remarkable saving prolong network lifetime, by selecting toward sink node, respect OFs considered literature.
