With the rapid increase in deployment of smart meters across North America, utility resources such as water, gas and electricity consumption data is being collected at a much higher granular level. The huge amount of data is being used to make demand-response applications smarter. A large part of this deployment of smart utility networks and Advanced Metering Infrastructure (AMI) is being done using...
We introduce ORTHCA (On-demand Routing with Two Hop Coordinates Awareness) a method for minimizing the dissemination of route requests in mobile ad hoc networks (MANET). The selection of relaying nodes is implemented by first computing the best two-hop relay nodes R2(u) whose Euclidean Distance to four polar points are the shortest among all two-hop neighbors N2(u), and then determining one-hop relay...
To evaluate the performance of delay for Network-on-Chip (NoC) at system-level design as early as possible, a delay estimation methodology based on M/G/1 queuing theory is proposed in the paper. In this methodology, the influence of the finite buffer resources and virtual channels in NoC router on the packet latency is taken into account, and the backward algorithm is used to calculate the network...
Cloud environments are being increasingly used for the deployment and execution of service-based business processes (SBPs). Among other properties, cloud provides elasticity in order to guarantee provisioning of necessary resources that ensure a smooth functioning of cloud services despite changes in solicitations. Provisioning of elastic infrastructures and platforms is not sufficient to provide...
This paper presents the magnetic field modeling-based energy efficient routing for WSN which models the routing problem as a current-carrying solenoid and a free to turn magnet put into a uniform magnetic field respectively. The optimal routing is then performed through the path with the maximum generated magnetic field intensity for the solenoid technique and with minimum torque for the magnetic...
This paper explores the cooperation between the new standards for "Low Power and Lossy Networks'' (LLNs): IETF RFC 6971, denoted ``Depth-First Forwarding in Unreliable Networks'' (DFF) and the ITU-T standardised routing protocol "LOADng''. DFF is a data-forwarding mechanism for increasing reliability of data delivery in networks with dynamic topology and lossy links, using a mechanism similar...
Load balancing and energy efficient are recognized as a crucial issue in ad hoc networks. Several routing protocols have been proposed in order either to distribute equitably the workload among the nodes of network or to consume in efficient way the residual energy of nodes. In this paper, a novel approach is proposed to enhance the AODV routing protocol by considering the node capacity for relaying...
To solve the congestion of NoC caused by overload such as injection rate increase, this paper proposes a novel routing algorithm, that is Dynamic and Mixed Routing(MIXROUT) which is based on XY Routing(XY) and Multiple and Load-Balance Path Routing(MULTI). Although MULTI is an adaptive routing that can relieve traffic congestion state, it has a higher operating power and temperature than other routing...
Protocols are currently being designed where a connection can simultaneously send traffic across multiple routes (or paths) of a communication network; for example, the IETF's MP-TCP protocol. Traditional single-path congestioncontrol protocols, which increase and decrease transmission rates depending on the level of congestion, can be argued to implicitly solve a network-wide utility optimization...
In this paper, we study the delay performance of backpressure routing algorithms using LIFO schedulers (LIFO-backpressure). We uncover a surprising behavior in which, under certain channel conditions, the average delay of packets decreases as the traffic load in the network increases. We propose and analyze a queueing-theoretic model under which the scheduler can transmit packets only if the queue...
Opportunistic routing, offering relatively efficient and adaptive forwarding in low-duty-cycled sensor networks, generally allows multiple nodes to forward the same packet simultaneously, especially in networks with intensive traffic. Uncoordinated transmissions often incur a number of duplicate packets, which are further forwarded in the network, occupy the limited network resource, and hinder the...
A branch of green networking research is consolidating. It aims at routing traffic with the goal of reducing the network energy consumption. It is usually referred to as Energy-Aware Routing. Previous works in this branch only focused on pure IP networks, e.g., assuming an Open Shortest Path First (OSPF) control plane, and best effort packet forwarding on the data plane. In this work, we consider...
An important problem that confronts P2P network is to efficiently search the node that stores a particular data. Chord is a distributed lookup protocol that addresses the problem. However, the chord protocol has not yet efficiently resolved the problem. In this paper an improved Chord algorithm is presented, which considers the node's actual ability, the physical location relationship, the routing...
Load-balanced switch fabrics offer the promise of very high capacity without the requirement of increased operating rates. We provide a novel solution to the well-known cell reordering problem, which arises in load-balanced switch fabrics if different paths through the switch fabric have different delays. We give a simple sorting circuit, easily implemented in hardware, that can be placed in the final...
Planning for recovery from exogenous or endogenous failures or outages of complex networks, including communications networks, power stations and entire grids as well as physical-transport networks such as pipelines, trucking, airways and railroads—for the purpose of smartly executing recovery—present planning difficulties because of the combinations of events which can occur, whether random, weather-induced,...
The optical network with additional optical transport system is considered. Classification of methods of communication is given. Schedules of dependence of key parameters of communication are deduced. Researches were spent on the basis of the statistical data.
Flooding of route requests or link states is a necessity in many routing protocols for mobile ad hoc networks (MANET), and several mechanisms have been devised to make flooding more efficient; however, all flooding approaches to date are such that the number of neighbors each node must use to relay a flooded packet grows as the node density increases. A new method, called ORCA (On-demand Routing with...
Delay-based Dual-rail Pre-charge Logic (DDPL) is a logic style introduced with the aim of hiding power consumption in cryptographic circuits in order to prevent Power Analysis (PA) attacks. Its particular data encoding allows to make the adsorbed current constant for each data input combination, irrespective of capacitive load conditions, which allows to design a PA-resistant circuit without routing...
The peer-to-peer (P2P) communication model has gained an enormous research interest in the last few years due to its promising properties (e.g., decentralization, self-organization, scalability, etc.) to build large scale distributed applications. However, the P2P systems are characterized by their dynamic behavior as peers can frequently join and leave the network. This property makes the data availability...
RPL, the routing protocol proposed by IETF for IPv6/6LoWPAN Low Power and Lossy Networks has significant complexity. Another protocol called LOADng, a lightweight variant of AODV, emerges as an alternative solution. In this paper, we compare the performance of the two protocols in a Home Automation scenario with heterogenous traffic patterns including a mix of multipoint-to-point and point-to-multipoint...
