A Lightweight Framework for Efficient M2M Device Management in oneM2M Architecture Recent years have witnessed an explosion in the number and types of physical devices connected to the Internet. This exponential growth in the volume of objects poses challenges in terms of managing the connected M2M devices. A unified approach for efficient management of the M2M devices while preserving scalability is necessary. This paper proposes an M2M device management framework that can be deployed in a cloud system, M2M gateway or even inside a mobile application. CoRE Link Format is used for lightweight description of smart M2M devices. The capabilities of CoRE Link are extended to describe legacy M2M devices as a part of Internet of Things ecosystem. Open Mobile Alliance Lightweight M2M (OMA LwM2M) Technical Specifications are used in the framework to provide M2M service enablement for end users. Selfmanagement of the M2M device configurations is outlined. The capabilities of the framework are exposed using RESTful web services. oneM2M architecture for device management is described which integrates the proposed framework. Its software implementation is examined to be ultralightweight. Utilization of CoRE Link settles the heterogeneity of the managed devices and promotes interoperability. Finally the paper summarizes the contributions and concludes with future directions.

MQTTbased Middleware for Container Support in Fog Computing Environments Distributed architectures where the Internet of Things (IoT) and the cloud are efficiently integrated play an increasingly important role for IoT solutions. Among these architectures, there is a growing interest in the ones that support the opportunity of functionality offloading towards either intermediate fog nodes or IoT end devices. Relevant existing research work has mainly focused so far on virtual machine and container migration to intermediate fog nodes and on migration of very simple functions to IoT endpoints (to preserve their limited resources available). In this paper, we originally concentrate on the gap associated with benefitting from fog functionality at resourcepowerful IoT endpoints, to create a continuum deployment that glues IoT devices and the cloud. In particular, this paper originally presents a middleware that manages application deployment and lifecycle by simplifying and optimizing management operations such as device configuration and application constraint satisfaction. The proposed solution particularly fits highly articulated scenarios with large numbers of IoT devices and intermediate fog nodes, by supporting the opportunity to offload functionality in a split way between IoT endpoints and edge nodes. The reported experimental results confirm the feasibility of our approach in term of overhead, scalability, and application lifecycle management.
