The continuous performance race led wireless industry to a ubiquitous adoption of heterogeneous architecture with small cells. Although, the extreme densification offers the largest increase in the network capacity, it also challenges more valuable system metrics like quality of service (QoS) for users with various traffic types. While previously used to boost capacity in the cellular system, radio...
Although Fog computing specifies a scalable architecture for computation, communication and storage, there is still a demand for better Quality of Service (QoS), especially for agile mobile services. Both industry and academia have been working on novel and efficient mechanisms for QoS provisioning in Fog computing. This paper presents a classification of services according to their QoS requirements...
Network Functions Virtualization (NFV) is a new network paradigm that has been strongly promoted from both scientific community and telecom industry, where network functions (NFs) such as firewalls, load balancers, gateways among others, are virtualized, isolated from middleboxes and housed on one or more industry standard computing nodes. One of the main challenges for service providers when they...
This paper presents the problem of optimizing Radio Access Technology (RAT) selection and traffic offloading in a Multi RAT Heterogeneous Network composed by cellular and WiFi networks. The main idea is to distribute the traffic load of the system over the available access networks, while making an efficient use of the radio resources in the long-term. In this sense, a higher and fair WiFi resource...
Realizing the reasonable allocation of transmission loss through locational marginal price is very important. It can guide the efficient use of transmission network and its reasonable planning. Because locational marginal price calculation based on DC-OPF model cannot reflect the marginal cost of transmission loss, a DC-OPF calculation method that considers the correction of transmission loss and...
Personal emergency response systems (PERS) such as Philips Lifeline help seniors maintain independence and age in place. PERS can use predictive analytics to help risk stratification and promote response-efficient emergency services. This paper presents a framework for estimating significant associations between Lifeline user characteristics and occurrence of emergency events. Predictive variables...
With the application of modern communication, control and measurement technology based on microelectronics and computer, a large number of microelectronic devices have been applied in the power generation, transmission and production links of power plants. In order to ensure the safe operation of all kinds of electronic equipment, it is necessary to install surge protector (SPD). In this paper, MATLAB...
In this paper, a near Optimum Power Allocation (OPA) for a cooperative jamming relay network is proposed, by using physical layer security to protect the user's messages from relay's interception. The network uses Amplify and Forward (AF) relay to enlarge the coverage area, however the relay is untrusted. By defining secure Energy Efficiency (EE) as the ratio of the instantaneous secrecy rate to the...
In order to balance the number of outbound and inbound tasks of each aisle and improve the working efficiency of the multi-tier shuttle system, three principles of storage location assignment were put forward: the principle of minimum correlation degree, the principle of equalization of product items and the principle of equalization of tasks, which were expected to be followed when storing products...
Increasing dependence on groundwater as a reliable source of water in the rural areas has resulted in its indiscriminate extraction without considering the recharging capabilities of the aquifers as well as other environmental factors. As the availability of groundwater is highly inconsistent and exhibits substantial variations across the country, management of groundwater resources in the Indian...
As cloud computing becomes popular, Platform as a Service (PaaS) plays an important role in a modern cloud system. The orchestration and efficiency attract more attention and demand a more intelligent solution. In this paper, we present Next Generation PaaS (NG-PaaS) which provides resource management, application management and performance monitoring. The NG-PaaS is built on docker to enable fine-grained...
The flexible spin-lock model (FSLM) unifies suspension-based and spin-based resource sharing protocols for partitioned fixed-priority preemptive scheduling based real-time multiprocessor platforms. Recent work has been done in defining the protocol for FSLM and providing a schedulability analysis without accounting for the implementation overheads. In this paper, we extend the analysis for FSLM with...
Earlier, Chao pioneered the very first closed-form solution (CFS) of the number of control related states (CRSs) for k-th order systems, which was the first step in facilitating an exponential computation time for enumerating reachable states of a particular large Petri net (PN), reducing this to within a second. This paper progresses a step further in enumerating the control related states for double-deficient...
System-of-Systems (SoS) with real-time communication networks are gaining more importance for many safety relevant application areas such as automotive, medical monitoring and telemedicine in health-care systems. This paper introduces a simulation framework capable of generating and simulating application scenarios of both time-triggered and rate constrained messages with their respective communication...
Although federated cloud computing has emerged as a promising paradigm, autonomous orchestration of resource utilization within the federation is still required to be balanced on the basis of workload assignment at a given time. Such potential imbalance of workload allocation as well as resource utilization may lead to a negative cloudburst within the federation. The analytical models found in the...
Live VM migration is a technique that consists of a selection process and a migration process to migrate a VM from one host to another in the same data center without changing the IP address, or in a different data center with necessity to the VM to get a new IP address. The changing of IP address results into a mobility problem, which may render the service unreachable. In this paper, we propose...
In this paper, we propose PreDA-a preferencebased truthful double auction for dynamic spectrum access (DSA) networks where multiple heterogeneous spectrum bands are sold by the primary users and bought by the secondary users. We consider channels' heterogeneity and multi-bids from buyers, and also consider buyers' preferences for the channels. We use the signal to interference and noise ratio (SINR)...
Current Distributed Radio Access Networks (DRANs), which are characterized by a static configuration and deployment of Base Stations (BSs), have exposed their limitations in handling the temporal and geographical fluctuations of capacity demands. At the same time, each BS's spectrum and computing resources are only used by the active users in the cell range, causing idle BSs in some areas/times and...
The paper presents basic control algorithms for vehicle platooning prototype car. The car is designed to be used in vehicle platooning research, namely in studying longitudinal control algorithms for vehicle platooning. It employs various sensors and devices that allow indoor research of platoon behavior. Therefore, the control algorithms can be designed and analyzed before implementing them within...
Starting from a hypothetical open shop production quantity estimation problem with weakly formulated objective function, this paper comparatively discusses a manual heuristic solution and an IBM-ILOG based numerical solution. Problem complexity is managed by specific partitioning strategies in the construction of heuristic solution instances. The study may serve as starting point in the systematic...
