“…Media transmission in the context of IoT is a topic that has been focus of research in recent years. Specifically, in Reference 20, the authors introduce the concept of “Phone of things” to recycle some of the mechanisms utilized in VoIP to support media communications under IoT. Another scheme that exploits VoIP schemes in the context of IoT is presented in Reference 21.…”

Wireless personal area networks (WPANs), as most IoT networking technologies, rely on constrained low power devices that support a trade‐off between signal coverage and transmission rates. WPANs are characterized for medium to low transmission rates over low distances. The transmission rates, however, are high enough to support maximum transmission unit (MTU) sizes that are large enough to enable the transmission of IPv6 datagrams. One such WPAN technologies is associated with the IEEE 802.15.4 physical layer. Because IEEE 802.15.4 does not natively support IP encapsulation, an adaptation mechanism known as IPv6 over low‐power wireless personal area networks (6LoWPAN) is used to this end. For large datagrams like those generated when transmitting speech frames, 6LoWPAN fragments them in order to comply with the 127‐byte IEEE 802.15.4 MTU size. Fragmentation, however, aggravates the effects of network packet loss. This article explores this problem and attempts to find a mechanism that overcomes these limitations. Specifically, it introduces a hybrid error correction algorithm that dynamically adjusts the number of fragments that are transmitted in order to balance application layer loss and transmission rate.

“…To the best of our knowledge, PoT [8] is the first proposition in the literature of a general-purpose, open-source, and multi-tier IoT framework based on the integration between phones (PSTN and VoIP) and IoT technologies. Previous research has targeted specific applications and employed limited phone functionalities in third party systems as their proposed IoT systems.…”

“…Figure 1 depicts the proposed LTC system. The LTC system is based on the PoT architecture proposed in [8], and it inherits its enabling technologies and modular design philosophy. LTC consists of a PoT gateway, a set of WiFi-enabled RFID door-entry nodes distributed along with the entrances of the rooms within the premise, and assistive cloudhosted services (namely, MongoDB database and Dialogflow's chatbot agent).…”

“…With slight tweaks to the original interactional behavior between the PoT gateway and the Dialogflow [29] proposed in [8], the PoT gateway is configured such that once a user picks up the phone, the embedded Asterisk server waits for the user utterance. The embedded Asterisk server records the user's utterance as an audio file and saves it to the PoT gateway.…”

Phone of Things (PoT) extends the connectivity options for IoT systems by leveraging the ubiquitous phone network infrastructure, making it part of the IoT architecture. PoT enriches the connectivity options of IoT while promoting its affordability, accessibility, security, and scalability. PoT enables incentive IoT applications that can result in more innovative homes, office environments, and telephony solutions. This paper presents the Location Transparency Call (LTC) system, an intelligent phone dialing system for businesses based on the PoT architecture. The LTC system intelligently mitigates the impact of missed calls on companies and provides high availability and dynamic reachability to employees within the premises. LTC automatically forwards calls to the intended employees to the closest phone extensions at their current locations. Location transparency is achieved by actively maintaining and dynamically updating a real-time database that maps the persons’ locations using the RFID tags they carry. We demonstrate the system’s feasibility and usability and evaluate its performance through a fully-fledged prototype representing its hardware and software components that can be applied in real situations at large scale.
