Abstract:The numerous and diverse applications of the Internet of Things (IoT) have the potential to change all areas of daily life of individuals, businesses, and society as a whole. The vision of a pervasive IoT spans a wide range of application domains and addresses the enabling technologies needed to meet the performance requirements of various IoT applications. In order to accomplish this vision, this paper aims to provide an analysis of literature in order to propose a new classification of IoT applications, specify and prioritize performance requirements of such IoT application classes, and give an insight into state-of-the-art technologies used to meet these requirements, all from telco's perspective. A deep and comprehensive understanding of the scope and classification of IoT applications is an essential precondition for determining their performance requirements with the overall goal of defining the enabling technologies towards fifth generation (5G) networks, while avoiding over-specification and high costs. Given the fact that this paper presents an overview of current research for the given topic, it also targets the research community and other stakeholders interested in this contemporary and attractive field for the purpose of recognizing research gaps and recommending new research directions.

Summary In multidomain optical networks (MDONs) the emerging multimedia, multivendor applications–based scheduled traffic (ST) is periodic and repeated day by day. The traffic is heavy during the working hours and slack during the non‐office hours. This results in the scarcity of network resources during the working hours, leading to the increased blocking of requests, even though there remains relatively large underused capacity during the non‐office hours. To use the network resources uniformly and efficiently, the demands may be slided within or shifted along the time zones/windows. In this paper, we first propose a heuristic algorithm, time‐aware routing and wavelength assignment (TA‐RWA), which allocates resources without traffic balancing (TB) for the ST in MDON. Time‐aware routing and wavelength assignment policy is then used as a benchmark for comparison with the 3 different TB solutions (named as P1‐TB, P2‐TB, and P3‐TB), in which the network load is redistributed by rescheduling the intradomain and interdomain demands. We performed extensive simulation experiments in MATLAB environment and compared the proposed policies with the existing ordering policies. From the results, it can be inferred that the proposed TB policies outperform the TA‐RWA, and the existing strategies of the blocking probability, resource utilization ratio (RUR), and percentage of intradomain and interdomain connections established. The best performance is achieved using P3‐TB strategy, in which requests are slided within, and shifted, along different time windows. The strategy shows about 70% reduction in the percentage blocking probability with respect to the TA‐RWA and the existing strategies.

“…A large amount of work similar to mobile clouds is done on the concept of offloading and obtaining energy efficiency by doing so [6], [24]. Offloading means moving data from mobile devices to the cloud or from the physical infrastructure to a network made by the mobile devices, so that it uses available resources to make the entire network more efficient [25].…”

Mobile clouds are an ongoing research topic that has yet to become ubiquitous as the now popular cloud paradigm. This is because of a number of issues with mobile clouds that still need to be addressed such as: incentives, security, privacy, context, data management, usability, and cost benefits. Out of these issues, the most important one that needs to be addressed is the issue of incentives, without which mobile clouds cannot gain enough users for the concept to be useful. Unlike public, company-owned cloud systems, in mobile clouds, the amount of resources or processing power is directly dependent on mobile cloud users that are in the proximity of the individual that requires extra resources. With an increase in the number of mobile cloud users willing to share resources or willing to use the service offered by others, comes an increase in the likeliness that enough mobile-cloud-enabled devices will be available. In this paper, we study incentives for mobile cloud systems and consider as a solution an evolutionary market-based approach to create these incentives. Creating a market for these systems is particularly difficult because of the large number of individuals that need to be involved and their high mobility.
