The Internet of Things (IoT) can support a significant number of services including those in smart homes and the automation of industries and public utilities. However, the growth of these deployments has posed a significant challenge especially in terms of how to build such deployments in a highly resilient manner. The IoT devices are prone to unpredicted failures and cyber-attacks, i.e. various types of damage, unreliable wireless connections, limited transmission power, computing ability, and storage space. Thus resilience is essential in IoT networks and in the services they support. In this paper, we introduce a new approach to resilience in IoT service embedding, based on traffic splitting. Our study assesses the power consumption associated with the services embedded and the data delivery time. The results are compared to recent approaches in resilience including redundancy and replication approaches. We constructed an optimization model whose goal is to determine the optimum physical resources to be used to embed the IoT virtual topology, where the latter is derived from a business process (BP). The embedding process makes use of the service-oriented architecture (SOA) paradigm. The physical resources of interest include IoT links and devices. The model made use of mixed integer linear programming (MILP) with an objective function that aimed to minimize both the total power consumption and the traffic latency. The optimization results show that the power consumption is reduced and the data delivery time is reduced in the service embedding approach where the proposed traffic splitting approach is employed resulting in the selection of energy efficient nodes and routes in the IoT network. Our methods resulted in up to 35% power saving compared to current methods and reduced the average traffic latency by up to 37% by selecting energy-efficient nodes and routes in IoT networks and by optimizing traffic flow to minimize latency.

“…Multiplexers/Demultiplexers are used on the C-band supporting 80 wavelengths, and EDFAs and dispersion compensators are used to improve the quality of the optical signal over the long distances considered. This setup gave the ability to test applications, traffic flow and latency [30]-38] over various long distances similar to actual distances between cities in a typical core network [18]. In order to demonstrate end-to-end communication, two processing nodes were connected through an IP/WDM core network and a PON cell as shown in Figure 5, an IPTV Camera was connected to the first processing cell and streams live video throughout the processing cell, over the IP/WDM Core networks nodes, and to the OLT/ONU.…”

Passive optical networks (PON) technology has recently been proposed as a solution for scalability, energy efficiency, high capacity, low cost, flexibility and oversubscription issues in data centres. This paper experimentally demonstrates and discusses the implementation of a server centric PON based data centre architecture with high speed and reliability. The architecture is set up using a set of servers grouped into racks directly connected together and to the Optical Line Terminal (OLT) through gateway servers. The switching and routing functionalities have been embedded into servers using 4x10GE Xilinx NetFPGA. Flow continuity has been observed through live video streaming using IP cameras transmitting over up to 110 km optical connections through WDM nodes and the PON network.

The demands of video traffic transmission have grown rapidly in recent years. The emergence of converged network alleviates heavy burden on cellular network by introducing broadcasting. The transmission cost of contents with large demands can be effectively reduced. The content distribution strategy compromising between broadcasting and unicasting plays an important role in improving the performance of the converged network. To this end, we formulate the content delivery in a converged network by a game with three players, which are broadcast network service provider, unicast network service provider and a content provider. The cooperation without reward sharing among these players is formulated as a Stackelberg game. In this game, the two service providers are leaders to determine their transmission prices in a competitive way. The content provider is the follower to decide the content distribution strategy. Its Nash Equilibrium is derived consequently. In addition, we investigate the cooperation with reward sharing among the three players by introducing Shapley Value model. According to numerical results, it shows that the proposed Shapley Value based reward sharing scheme can improve the fairness of network cooperation. The gain of content provider using converged strategy over single mode transmission is validated as well.
