“…The focus in the literature has shifted towards making the whole IoT infrastructure energy efficient [26] as opposed to optimizing only individual layers namely the device layer, access layer, or the cloud. The works in [27] and [28] proposed the use of Passive Optical Networks (PONs) to extend cloud and fog services closer to the user premises, respectively. Optical based networks are expected to become increasingly important to support edge and fog computing in the next decades.…”

“…The third layer is still part of the PON access network; however, it differs in terms of processing capability. Several high-end servers are used to form a fog collocated with the OLT [27], [48]. Thus, a substantial amount of service demands aggregated from the ONUs can be hosted and processed on the fog connected to the OLT's Ethernet input.…”

In the near future, the number of Internet connected objects is expected to be between 26-50 billion devices. This figure is expected to grow even further due to the production of miniaturized portable devices that are lightweight, energy, and cost-efficient. In this paper, the entire IoT-fog-cloud architecture is modeled, the service placement problem is formulated using Mixed Integer Linear Programming (MILP) and the total power consumption is jointly minimized for processing and networking. We evaluate the distributed processing paradigm for both the un-capacitated and capacitated design settings in order to provide solutions for the long-term and short-term basis, respectively. Furthermore, four aspects of the IoT processing placement problem are examined: 1) IoT services with non-splittable tasks, 2) IoT services with splittable tasks, 3) impact of processing overheads needed for inter-service communication and 4) deployment of special-purpose data centers (SP-DCs) as opposed to the conventional general-purpose data center (GP-DC) in the core network. The results showed that for the capacitated problem, task splitting introduces power savings of up to 86% compared to 46% with non-splittable tasks. Moreover, it is observed that the overheads due to inter-service communication greatly impacts the total number of splits. However much insignificant the overhead factor, the results showed that this is not a trivial matter and hence much attention needs to be paid to this area to make the best use of the resources that are available at the edge of the network.

SUMMARY In this paper, we propose a Mobile Edge Internet of Things (MEIoT) architecture by leveraging the fiber-wireless access technology, the cloudlet concept, and the software defined networking framework. The MEIoT architecture brings computing and storage resources close to Internet of Things (IoT) devices in order to speed up IoT data sharing and analytics. Specifically, the IoT devices (belonging to the same user) are associated to a specific proxy Virtual Machine (VM) in the nearby cloudlet. The proxy VM stores and analyzes the IoT data (generated by its IoT devices) in realtime. Moreover, we introduce the semantic and social IoT technology in the context of MEIoT to solve the interoperability and inefficient access control problem in the IoT system. In addition, we propose two dynamic proxy VM migration methods to minimize the end-to-end delay between proxy VMs and their IoT devices and to minimize the total on-grid energy consumption of the cloudlets, respectively. Performance of the proposed methods is validated via extensive simulations.

In this paper, an evaluation is performed of 2.5Gbps bi directional GPON based Fiber-To-The-Home (FTTH) link using advanced modulation formats. Gigabit Passive Optical Network (GPON) is a promising solution for increasing bandwidth requirements of customers which supports triple play services and is being considered as a solution for mobile back haul network. It also enables the delivery of cloud services with a high interconnection speed. The performance of the proposed system was studied when a single wavelength and two wavelengths were used for triple-play services with different modulation schemes. This paper is aimed to provide a comparison of the performance of different modulation formats for GPON based simulation of an actual architecture considering Q factor, BER, optical power and OSNR.The outcome shows that better results were observed for RZ DQPSK.
