Retrieving Monitoring and Accounting Information from Constrained Devices in Internet-of-Things Applications

Abstract

Internet-of-Things (IoT) is envisioned to provide connectiv-ity to a vast number of sensing or actuating devices with limited com-putational and communication capabilities. For the organizations that manage these constrained devices, the monitoring of each device's oper-ational status and performance level as well as the accounting of their re-source usage are of great importance. However, monitoring and account-ing support is lacking in today's IoT platforms. Hence, this paper stud-ies the applicability of the Constrained Application Protocol (CoAP), a lightweight transfer protocol under development by IETF, for eciently retrieving monitoring and accounting data from constrained devices. On the infrastructure side, the developed prototype relies on using stan-dard building blocks oered by the AMAAIS project in order to collect, pre-process, distribute, and persistently store monitoring and account-ing information. Necessary on-device and infrastructure components are prototypically implemented and empirically evaluated in a realistic sim-ulation environment. Experiment results indicate that CoAP is suited for eciently transferring monitoring and accounting data, both due to a small energy footprint and a memory-wise compact implementation. Abstract.

Network layer inter-operation of Device-to-Device communication technologies in Internet of Things (IoT)

“…This information creates overhead and the processing needs additional processing power. The results in [12,13] shows that fragmentation can significantly degrade the performance of devices in the IoT ecosystem. Fragmentation of data before transmission may also open the transmission to security threats.…”

Bridging the SNMP gap: Simple network monitoring the internet of things

“…One example of using Zenoss in IoT monitoring was given in [35]. Mazhelis et al have analyzed the possibilities of use of the CoAP protocol for monitoring of IoT infrastructure as well as adapting existing Accounting and Monitoring of Authentication and Authorization Infrastructure Services (AMAAIS) project [36] for such use [37]. Although NMS products can differ significantly from each other, practically all of them support at least data gathering via SNMP.…”

Managing things and services with semantics: A survey

“…CoAP-based protocols (e.g. [16]) have also been investigated, nonetheless, these are also non standardized custom protocols on top of the application layer protocol. Considering that the IoT to some degree originated from RFID, we surveyed other technologies than those based on ISO/OSI (Internet)-like stacks.…”
