For network managers, it is important to find the burst network traffic as soon as possible. However, most network monitoring system can not find the source of the problematic flow in a short time. In this paper, we design an efficient realtime deep packet inspection (DPI) monitoring system, which can help us observe not only the topology but also the protocol such as Facebook or Google. To make the...
Optical Transport Networks (OTNs) are composedof multiple devices. The configuration of these devices is man-ually done by system operators. Besides laborious and error-prone, this configuration also limits the client customizationand configuration of the network. One way out of this lack ofcustomization is the separation of control and data planes fromthese devices. The Software Defined Networks...
The mobile ad-hoc networks (MANETs) represent a broad area of study and market interest. They provide a wide set of applications in multiple domains. In that context, the functional and non-functional monitoring of these networks is crucial. For that purpose, monitoring techniques have been deeply studied in wired networks using gossip-based or hierarchical-based approaches. However, when applied...
Recently, Software Defined Network (SDN) technology has become widely used to take advantage of its features, including capabilities for optimization, flexibility, and customization. Many companies and organizations are applying this technology to build SDN networks for testbeds or production networks to address their requirements for optimization and customization. Currently, north bound and south...
Named-Data Networking (NDN) is a novel clean-slate architecture for Future Internet. It has been designed to take into account a new use of the Internet and especially accessing content for a large number of users, and it integrates several features such as in-network caching, security or multipath. As NDN relies on content names instead of host address, it cannot rely on traditional Internet routing,...
As MANET is an infrastructure less, problems related to reduce Flooding by Propagating Neighborhood Information Algorithm (PNIA) is instant path transformation with reverence to transform in topology and blocking in the network. In this paper we have explained on PNIA with Grid Fisheye State Routing Protocol for MANET and implemented with various metrics in NS3 Simulator. Also the proposed work is...
Volunteer cloud is a new paradigm of cloud computing where volunteer resources, i.e. user machines are used instead of (or in addition to) dedicated resources, i.e. data centers. Although volunteer clouds offer potential benefits in terms of energy and cost saving as well as elasticity, the volatility and the scalability of the volunteer resources are still open challenges that need to be studied...
This paper investigates a double-integrator consensus problem for multi-agent networks (MANs) with nonlinear dynamics, where each agent is governed by both time-varying position and velocity consensus terms. The following three cases are carefully analyzed: 1) networks with fixed topology; 2) networks with controlled switching topology; and 3) networks with random switching topology. Based on previous...
We address the design space exploration of wireless body area networks for wearable and implantable technologies, a task that is increasingly challenging as the number and variety of devices per person grow. Our method efficiently decomposes the problem into smaller subproblems by coordinating specialized analysis and optimization techniques. We leverage mixed integer linear programming to generate...
OpenStack has been widely acknowledged to be one of the most important open source cloud platforms. In order to perform experimentally driven research in the area of cloud and cloud networking, there is however a big gap, because most researchers do not have access to a large cloud deployment and cannot change networking or compute infrastructure in order to test their algorithms and protocols on...
In Skip Graph, a structured overlay, each node constructs its routing table by choosing connected nodes based on its membership vector. However, membership vectors are determined randomly; therefore, nodes do not always form an ideal topology. This can cause the route length to be long. Therefore, we propose Self-Refining Skip Graph, a structured overlay where each node refines its routing table toward...
Several data center applications such as Hadoop and OpenStack VM provisioning utilize group communication (one-to-many or many-to-many transfers). Since these applications require reliable and stable delivery, they rely on TCP for all group communications. Even though multicast lends itself naturally to these group communication patterns, it has remained largely under-deployed in the Internet owing...
It is critical to provide sustained data throughput in edge computing, where several sensor devices generate information that needs to be fused and used for decision making in e.g., disaster incident scenes. To this end, we compare the effectiveness of two protocols, Hybrid Wireless Mesh Protocol (HWMP) and Greedy Perimeter Stateless Routing (GPSR), based upon their ability to stream data in a mesh...
IPv6 has become popular now-a-days among the ISPs, organization and end users because of its magnificent features and due to the limitation of IPv4. The migration from IPv4 to IPv6 is mandatory due to the address scarcity and security vulnerabilities of IPv4. But the deployment of IPv6 is far beyond satisfactory level in Bangladesh. So, a smooth as well as effective transition mechanism is needed...
Energy consumption, traffic adaptability, fast data collection, etc are the major issues in wireless sensor networks (WSNs). Most existing WSN protocols are able to handle one or two of the above issues with the other(s) being compromised. In order to reduce the energy consumption of wireless sensor nodes while having fast data collection under different traffic generating rates, this paper proposes...
This paper provides a novel analysis of the global convergence properties of a well-known consensus protocol for multi-agent systems that evolve in continuous time on the n-sphere. The feedback is intrinsic to the n-sphere, i.e., it does not rely on the use of local coordinates obtained through a parametrization. It is shown that, for any connected undirected graph topology and all n ∈ N\{1}, the...
The technological rebellion has made current generations to depend more on the digital world in their day to day life. The effectiveness of the digital world has changed the learner's perceptive towards the education system. The impulsivegrowth of technology has increased the popularity of Information and Communication Technology which has created a research scope in Computer network domain thus Computer...
Spontaneous progress in the field of wireless sensor networks (WSN) have led to development of various protocols for reliable communication and increasing longevity of the network. While designing the protocols for WSNs, designers come across the issues like limited energy per node, limited bandwidth for communication, security, minimum communication and computational cost. This paper focuses on energy...
We propose the use of a graph-theoretic metric called Algebraic Connectivity (ALGC) computed on the egocentric network of an edge to quantify the extent of shared neighborhood between the end vertices of the edge/link in mobile sensor networks (MSNs). The chances for the egocentric network of an edge to stay connected increases with increase in the number of triangles involving the end vertices of...
Software Defined Networking (SDN) is a paradigm shift technology in networking. However, it is not practical to remove existing networks for building SDN networks or to replace all operating network devices with SDN-enabled devices. Therefore, SDN migration, which implies co-existing techniques and gradually moving to SDN, is an important issue. In this paper, we focus on how to integrate SDN networks...
