A delay-tolerant framework for integrated RSNs in IoT

摘要: The Internet of Things (IoT) represents an evolutionary vision that promises to identify and connect physical objects devices. This faces many challenges in terms integrating technologies, especially RFID-sensor networks (RSNs). In this paper, we introduce a framework for node deployment delay-tolerance RSNs under the IoT paradigm. Our is comprised two components. first SIWR, novel Smart Integrated WSNs RFIDs architecture classifies nodes into light super integrated nodes. SIWR employs optimal linear programming formulation cost-efficiently place RFID readers. However, architectures face significant connectivity challenges. settings assume no guaranteed contemporaneous end-to-end path between pairs. To end, second part our framework, DIRSN, optimized delay-tolerant approach networks. scheme data routing courier nodes' selection RSNs. DIRSN's minimizes delay across network without violating main dense-deployment load-balancing requirements. addition, DIRSN builds on SIWR's locate best set couriers promise provide connectivity. combined compared three types RSN integration results show approaches perform substantially better than other minimizing delay, cost, packet loss, handling extensive traffic demands.
