    Many Internet of Things (IoT) networks are created as an overlay over traditional ad-hoc networks such as Zigbee. Moreover, IoT networks can resemble ad-hoc networks over networks that support device-to-device (D2D) communication, e.g., D2D-enabled cellular networks and WiFi-Direct. In these ad-hoc types of IoT networks, efficient topology management is a crucial requirement, and in particular in massive scale deployments. Traditionally, clustering has been recognized as a common approach for topology management in ad-hoc networks, e.g., in Wireless Sensor Networks (WSNs). Topology management in WSNs and ad-hoc IoT networks has many design commonalities as both need to transfer data to the destination hop by hop. Thus, WSN clustering techniques can presumably be applied for topology management in ad-hoc IoT networks. This requires a comprehensive study on WSN clustering techniques and investigating their applicability to ad-hoc IoT networks. In this article, we conduct a survey of this field based on the objectives for clustering, such as reducing energy consumption and load balancing, as well as the network properties relevant for efficient clustering in IoT, such as network heterogeneity and mobility. Beyond that, we investigate the advantages and challenges of clustering when IoT is integrated with modern computing and communication technologies such as Blockchain, Fog/Edge computing, and 5G. This survey provides useful insights into research on IoT clustering, allows broader understanding of its design challenges for IoT networks, and sheds light on its future applications in modern technologies integrated with IoT.acceptedVersio

    Load Balancing Algoritms in Cloud Computing Environment: A Review

    Get PDF
    Cloud computing is an emerging internet based technology. Cloud is a platform providing pool of resources and virtualization. It is based on pay-as-you-go model. The numbers of users accessing the cloud are rising day by day. Generally clouds are based on data centers which are powerful to handle large number of users. The reliability of clouds depends on the way it handle loads, to overcome such problems clouds must be featured with the load balancing mechanism. Load balancing is required as we don’t want one centralized severs performance to be degraded. A lot of algorithms have been proposed to do this task. In this paper we have studied the various existing load balancing algorithms and then compared them based on various parameters like resource utilization, scalability, stability etc

    A Novel Technique for Task Re-Allocation in Distributed Computing System

    A distributed computing is software system in which components are located on different attached computers can communicate and organize their actions by transferring messages. A task applied on the distributed system must be reliable and feasible. The distributed system for instance grid networks, robotics, air traffic control systems, etc. exceedingly depends on time. If not detected accurately and recovered at the proper time, a single error in real time distributed system can cause a whole system failure. Fault-tolerance is the key method which is mostly used to provide continuous reliability in these systems. There are some challenges in distributed computing system such as resource sharing, transparency, dependability, Complex mappings, concurrency, Fault tolerance etc. In this paper, we focus on fault tolerance which is responsible for the degradation of the system. A novel technique is proposed based upon reliability to overcome fault tolerance problem and re-allocate the task. DOI: 10.17762/ijritcc2321-8169.15080

    The essence of P2P: A reference architecture for overlay networks

    Get PDF
    The success of the P2P idea has created a huge diversity of approaches, among which overlay networks, for example, Gnutella, Kazaa, Chord, Pastry, Tapestry, P-Grid, or DKS, have received specific attention from both developers and researchers. A wide variety of algorithms, data structures, and architectures have been proposed. The terminologies and abstractions used, however, have become quite inconsistent since the P2P paradigm has attracted people from many different communities, e.g., networking, databases, distributed systems, graph theory, complexity theory, biology, etc. In this paper we propose a reference model for overlay networks which is capable of modeling different approaches in this domain in a generic manner. It is intended to allow researchers and users to assess the properties of concrete systems, to establish a common vocabulary for scientific discussion, to facilitate the qualitative comparison of the systems, and to serve as the basis for defining a standardized API to make overlay networks interoperable
