Wireless Sensor Network (WSN) is widely used in IOT, military and environmental application. However, WSN is energy-constrained and the network nodes placed in hostile environment are hard to replace. Therefore, designing an energy-efficient routing algorithm is significant. Many solutions have been proposed to optimize energy consumption in conventional wireless sensor network, but they don't work...
Distributed Mininet implementations have been extensively used in order to overcome Mininet's scalability issues. Even though they have achieved a high level of success, they still have problems and can face bottlenecks due to the insufficient placement techniques. This paper proposes a new placement algorithm for distributed Mininet emulations with optimisation for Fat-Tree topologies. The proposed...
In topology representations such as maps, carbon nanotubes, and cellular networks, neighboring cells are assigned different exclusive colors to represent different characteristics. In the previous research, based on the fourcolor theorem, an algorithm that can allocate exclusive channels among neighbors using only four channels in a polygonal cluster sensor network is proposed. The performance of...
In order to solve the problem of instability clustering in Ad Hoc Networks with complex and changeable node motion, this paper proposes a weighted clustering algorithm based on node stability(SA-WCA). In this algorithm, we propose a node stability factor based on node received power, which does not need to calculate the specific distance between nodes and can only judge the relative motion between...
A smart meter Neighborhood Area Network (NAN) is a significant component for smart grid. The delay- sensitive communication in NAN, such as the interaction of power system control signal, usually requires the maximum allowed delay in the order of a few milliseconds. Therefore, it is crucial to investigate how to shorten the latency and guarantee real-time communications. Since the location of Data...
Instantiating a distributed application that involves extensive inter-node communication onto a network is a challenging task. In this work, we focus on the special case of mapping a network emulation experiment onto a cluster comprising several (possibly heterogeneous) physical machines. We automatically profile the available physical machine resources, and use this information, together with the...
In this paper, we concentrate on multi-target fusion and tracking problems in wireless sensor network (WSN) based on distributed clustering consensus filter. In particular, for the sake of the network lifetime and the tracking accuracy in multi-target cases, a distributed target-based clustering algorithm is proposed, which consists of the cluster member selection, the cluster head competition and...
This paper presents a new approach for distributed consensus-based estimation with low communication effort in cooperative networks, where a group of nodes cooperates to estimate source messages with information exchange achieving consensus among all nodes. A new distributed estimation algorithm is developed by adopting the novel approach of virtual clustering, in which the size of exchanged data...
In this paper, we propose a novel cloud-based approach for solving the optimal power routing problem in clusters of DC microgrids. To this end, we deploy oblivious network routing design. Each cluster includes multiple microgrids which are connected via DC links in a multi-terminal DC system in a meshed network topology. In the proposed framework, the energy will be transmitted from the microgrid...
Social network is becoming indispensable of people's lives in recent years. Community detection on real network continues to be a hotspot in data ming domain. As users may join multiple social circles and interest communities, and an abundance of information can be a reflection of users' preference, heterogeneous information fusion and overlapping community detection are two key issues researchers...
Allocating physical resources for virtual cluster is known as virtual cluster embedding problem, which has a very important influence on the performance of virtual cluster and resource utilization of the system. Meanwhile virtual cluster embedding, relative to the virtual network, includes more embedding elements: virtual machine, virtual switch, virtual link, virtual SDN controller and cluster system...
Software Defined Networking (SDN) technologies provide applications opportunities to manipulate underlying network flows and topologies via network controllers during runtime. In cloud environments, networked virtual machines can be enhanced by SDN by providing applications with controllable infrastructures to meet system-level quality requirements; however, customizing a suitable network topology...
Cloud platforms have emerged as a leading solution for computation. In the meantime, large computations have shifted from big parallel tasks to workflows of smaller tasks with data dependencies between them. Task placement is a major issue on Cloud platforms, especially considering the impact of data exchanges on cost and makespan. In this paper, we investigate the consequences of network contention...
This paper studies the multi-equilibria consensus problem for discrete-time multi-agent networks with fixed communication topologies. The agents are assumed to use the traditional distributed averaging based consensus algorithm that relies on neighbor information exchange. Given the graph of the network, two new notions of primary and secondary layer subgraphs are introduced, which are subsequently...
The topology of a Mobile Ad hoc Network (MANET) has substantial influence on its performance in that the transmission range and battery power of the nodes are not uniform in nature. The topology is susceptible to node and link failures which lead to network partitioning. Topology reconfiguration aims to recover from the failure and maintain the connectivity. Existing topology reconfiguration algorithms...
WIA-PA (Wireless Networks for Industrial Automation-Process Automation) standard has become one of the three major IEC (International Electrotechnical Commission) standards for industrial wireless networks technology, and multi-channel frequency hopping mechanism is significant for the performance of WIA-PA networks. Existing AFH (adaptive frequency hopping) mechanism for WIA-PA networks is based...
This paper discusses the Correntropy Induced Metric (CIM) based Growing Neural Gas (GNG) architecture. CIM is a kernel method based similarity measurement from the information theoretic learning perspective, which quantifies the similarity between probability distributions of input and reference vectors. We apply CIM to find a maximum error region and node insert criterion, instead of euclidean distance...
A Self-Enforcing Network (SEN), which is a self-organized neural network, is introduced to cluster medical data. In addition, a cue validity factor is defined, which affects the clustering of the data. The results show that a user can influence the clustering of data by SEN, thus allowing the analysis of the data depending on economical, medical or nursing interests. The described prototype includes...
Identification of protein complexes is very important to investigate the characteristics of biological processes. Most of existing protein complex clustering algorithms were often run only on a static protein-protein interaction (PPI) network. The dynamic characteristics of interactions were ignored. In order to solve the problem, a new clustering algorithm (TP-WDPIN) was proposed which is based on...
Cloud Computing (CC) is becoming increasingly pertinent and popular. A natural consequence of this is that many modern-day data centers experience very high internal traffic within the data centers themselves. The VMs with high mutual traffic often end up being far apart in the data center network, forcing them to communicate over unnecessarily long distances. The consequent traffic bottlenecks negatively...
