Ubiquitous robust data delivery for integrated RSNs in IoT

In this paper, we present URIA, a Ubiquitous Robust Integrated Approach for data delivery in integrated RFID-Sensor Networks (RSNs). The proposed approach deploys ubiquitous wireless nodes equipped with transceivers as couriers between integrated reader/relay nodes and access points in an IoT setting. In addition to guaranteeing a specific level of connectivity across the network, URIA maintains constraints on delay, such that a multi-path minimal-delay route is always provided between any source-destination pair. Our approach is formulated via a Semi-Definite Programming (SDP) solution and is compared against other IoT integrated schemes targeting connectivity and delay metrics. Simulation results show that our proposed approach outperforms rival schemes in terms of total latency and delivery rate. This is achieved while considering vast data generation rates, instantaneous topology changes, and high probabilities of failure over the established end-to-end paths.
