In nigh application, it is indispensable to discover or supervise the behavior of the surrounding situation at a fine resolution over large spatial-temporal scales therefore WSN (Wireless Sensor Network) is well-advised. Because of smaller size and low power requirement of sensor device use of WSN for watching the surrounding action is increased time to time. Numeral of sensor inside WSN is proportionate...
Due to the irregular topology of ultra dense cellular network (UDN), base station (BS)-centric methods are usually with low spectrum efficiency and not flexible for quality-of-service (QoS) guaranteeing. This paper investigates the QoS-aware interference coordination in UDN from a user-centric way (UCQA-IC). Targeting at enhancing the spectrum efficiency and user experience with controlled inter-cell-interference...
Apache Storm has recently emerged as an attractive fault-tolerant open-source distributed data processing platform that has been chosen by many industry leaders to develop real-time applications for processing a huge amount of data in a scalable manner. A key aspect to achieve the best performance in this system lies on the design of an efficient scheduler for component execution, called topology,...
In a complex heterogeneous wireless sensor networks (HWSN), the individual sensor node is equipped with extremely different battery capacity and computational capability. Node failure is an inevitable phenomenon which leads to decreasing the lifetime and Qos of the networks. Topology control is an energy-efficient technique to prolong the network lifetime and maintain the network Qos. In this paper,...
Worldwide Interoperability for Microwave Access (WiMAX) technology is a subdivision of the vast field of wireless communications, which breaks the restrictions of DSL, cable-modem or T1 infrastructure based wire line of our broadband Internet connections [1]. Wireless networking has become an important area of research in academic and industry. The four high-speed intensive applications such as high-speed...
5G Heterogeneous Networks (HetNets) represent a promising solution to meet the continuous traffic demand originated mainly by the new mobile applications with real and non-real time requirements, new devices, cloud services, IoT and the novel IoE applications. The incorporation of traffic offloading techniques to deal with these demands is an essential part to be implemented in the future networks...
MTC services are undergoing rapid increase; billions of MTC connections can be anticipated in a few years. When supporting MTC services in telecommunications networks, MTC traffic characteristics and its unique service requirements should be exploited in order to optimize resource utilization and offer satisfactory service quality for all devices. In this paper, we present an Information-Centric Virtual...
This paper addresses an energy efficient network topology management strategy which exploits the path diversity in a dual-hop backhaul network in order to lessen the power consumption by switching as many underutilized base stations as possible to a dormant mode. This scheme dynamically tunes the various states of the relay nodes and aggregation points in a dual-hop setup to meet a trade-off between...
Given cloud-based realization of a CDN service S (i.e., Content Distribution Network), QoS auditing captures the QoS violations that arise under various resource depletion and outage scenarios faced by S. Third-party control of the underlying cloud VM and storage nodes hosting the content (i.e., proxies of content server) raises the issue of reasoning about how well the CDN internal mechanisms are...
The diversity in the way different cloud providers offer their services, give their SLAs, present their QoS, support different technologies, etc., complicates the portability and interoperability of cloud applications, and favors vendor lock-in. Standards like TOSCA, and tools supporting them, have come to help in the provider-independent description of cloud applications. After the variety of proposed...
Infrastructure as a service (IaaS) has attracted significant attention from cloud research communities. While compute and storage resource management has been developed and studied to a greater extent, the use of network resource management in the context of IaaS is still in its early stages. There is a need for a comprehensive virtualization framework capable of providing users with low-level network...
One of the major tasks when deploying real-time Ethernet networks is their configuration to achieve real-time behavior. In this paper we present an approach for a self-configuring plug-n-play network that automatically sets up devices and offers hard real-time guarantees to such devices. A new architecture and a protocol based on OpenFlow are proposed to achieve a system that can react to failures...
A challenge in the adoption of the OpenFlow (OF)-based SDN paradigm is related to the limited number of OF rules supported by the network devices. The technology used to implement the OF rules is TCAM, which is expensive and power demanding. Due to this, the network devices are either very costly or they can support a very limited number of OF rules. One way to cope with this limitation, is to perform...
Aware of the benefits that Software-Defined Networking (SDN) can entail for traffic engineered services, the pan-European National Research and Education Network (NREN) Géant has started to work on an SDN-based solution to provide Bandwidth on Demand (BoD) services. The proposed solution relies on a framework called DynPaC, which is able to provide resilient L2 services taking into account bandwidth...
The Wireless sensor network (WSN) deployment areas in real time environment are often inaccessible and unreliable communication resulting in degradation of network performance. The critical issues in any WSN are QoS and energy. Post deployment, it may not always be feasible to replace the batteries in a WSN. Long hops of transmission maintaining the QoS with more energy consumption results in reduction...
Software-Defined Networking can be used to easily provision paths for business applications. However, such provisioning is static and is furthermore lost when application flows cross over to another operator domain. This paper proposes an online mechanism (SDNI) that considers application requirements and uses SDN to negotiate traffic policies between neighbouring operator domains. Hence, SDNI enables...
In recent years Wireless Sensor Networks (WSNs) are the most widely used networks and got attractive applications in various fields such as medical, military, safety agriculture and environmental monitorings etc. People are attracted to the networks which provide good services with less cost and judges the network based on their experience of network performance. The network performance seen by the...
Wireless mobile network consist of mobile nodes without wired connection between the nodes and that nodes will leaves as well as enters in the network due to the mobile nodes. Mobility management and topology maintenance is the major issue in wireless mobile network. Due to the mobility, packet loss and routing overhead will be high. To improve the overall performance proposed a new technique called...
The quality of service (QoS) in Smart Grid (SG) communications has a significant importance on emerging SG applications. Wireless sensor networks (WSNs) were considered as a compatible choice to fulfill this issue. In fact, WSNs could be widely used in a wide range of smart grid applications because they have been successfully adopted in several critical areas. Unlike other WSN applications, SG requires...
