The design, installation, and protection of wire and cable systems in substations are covered in this guide, with the objective of minimizing cable failures and their consequences
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...
In the past decades, various concepts of peer-to-peer (P2P) systems have been realized in desktop applications for stationary PCs. Last recent years show that computers have evolved to handy devices which can be used nearly everywhere, not only at home. For this reason, location-based services which allow to associate peers in a network with geographical positions, e.g. to track a device in emergency...

Three-Dimensional Networks-on-Chips (3D-NoCs) have been proposed as an auspicious solution, merging the high parallelism of the Network-on-Chip (NoC) paradigm with the high-performance and low-power cost of 3D-ICs. However, as technology scales down, the reliability issues are becoming more crucial, especially for complex 3D-NoC which provides the communication requirements of multi and many-core...
Ensuring security in routing protocols designed for Internet of Things (IoT) is more challenging owing to the fact that devices are resource constrained. The need for lightweight security mechanisms is apparent because cryptography based mechanisms have intense computation requirements. Although Routing Protocol for Low power and lossy networks (RPL) inherently comprises a few security mechanisms,...
Live Virtual machine (VM) migration is a promising solution for data center (DC) administrators to achieve a wide range of objectives - from load balancing to disaster evacuation. Ideally, live VM migration is seamless and the challenge is to minimize the downtime during which the VM is not responding to requests or providing the service. The duration of the downtime is mainly influenced by the migration...
The for equipment system of the complex network of command system of special structure and function, respectively from unit layer, sub network layer and network layer extraction reliability evaluation parameters, based on sub network efficiency established perception subnet, accused of subnet and combat the reliability index of the network and maintenance network, and each sub network reliability...
In ad hoc networks, backoff-based OR (opportunistic routing) protocols, which autonomously selects a forwarder among the potential forwarders based on a random backoff time, have been proposed. However, each potential forwarder must wait for the backoff time to avoid packet collisions among receivers. In addition, the terminal density strongly affects the performance since the backoff-based OR protocols...
Natural disasters impose significant threat to the electric grid and cause severe damages and blackouts. Presently, the power industry still relies on experiences to make recovery plans after natural disasters. In this paper, we study the repair and restoration of a transmission system. The problem consists of dispatching repair crews to fix damaged components and re-dispatching the available generators...
TSV failures due to manufacturing defects and thermal-induced latent defects result in yield and reliability issues in 3D-ICs. Recent work has shown different temperature mitigation techniques and fault tolerant architectures for 3D-ICs. It is known that TSVs are effective in reducing temperature by providing thermal conductivity. This is the first work that jointly considers temperature mitigation...
The ongoing research in the field of vehicular communication towards cooperative Intelligent Transport Systems (ITS) tries to tackle the ever increasing road traffic problems. In urban Vehicular Ad-hoc Networks (VANET), network disconnections happen frequently as a result of fast movement of vehicles, road layout constraints, and shadowing effects caused by buildings. Therefore, one of the key factors...
For wireless sensor networks in wide-area cropland environments, the routing protocol would be optimal if it is scalable for wide network coverage, energy-efficient for long network lifetime, and adaptive with frequent topology changes. In this paper, a wireless sensor network system with EBGR (Energy-Balanced, Greedy forwarding Routing) protocol was developed based on Memsic IRIS nodes and TinyOS...
Neighbourhood connection and network topology in modular robotic systems are frequently varied by users. Inter-communication of modular robotic systems is a challenge due to uncertainties of network topology. In this paper, we present a novel distributed communication protocol for modular robotic systems. The protocol is designed to deal with rapid changes of system reconfiguration. We demonstrated...
Life has become speedy in current scenario and vehicles play a vital role in this never ending race. Smart vehicles equipped with latest gadgets are becoming a part of intelligent transportation system (ITS) and point of attraction among drivers. Vehicular ad hoc networks (VANETs) is the environment of such smart vehicles that makes traffic functionality smooth and develops a path of infotainment...
The potentials of Internet of Things (IoT) are unlimited and a lot of IoT based applications have been recently explored. In IoT networks, anything can be enabled with network connectivity anytimes, and at anyplace. Path establishement from the source to the sink is an integral part of the IoT network. IPv6 Routing protocol for Low-power and Lossy networks (RPL) is a promising routing protocol for...

We give a formulation of the problem as an MILPand show that it is NP-hard. We propose a polynomial timeheuristic, called Iterative Split and Prune (ISP) that decomposesthe original problem recursively into smaller...
Large-scale storage systems often face node failures that lead to data loss. Cooperative regeneration has been extensively studied to minimize the repair traffic of simultaneously reconstructing the lost data of multiple failed nodes. However, existing cooperative regeneration schemes assume that nodes are homogeneous. They do not consider how to minimize the general regenerating cost when taking...
