Routing mechanism is one of the many ways to optimize the performance of Zigbee network that used battery-powered device. Therefore, a variety of routing algorithms are developed to obtain the optimal performance. One of the examples is Power-Source Aware Routing (PSAR) algorithm. However, PSAR algorithm has problem that the reconfiguration of battery powered node from communication path is not always...
This paper introduces a cognitive green topology management scheme for future 5Gnetworks, which can be used to reduce energy consumption in low traffic scenarios. The scheme is based on a backhaul link selection algorithm which aims to concentrate distributed traffic on fewer backhaul links by exploiting backhaul link diversity from other cells. A reinforcement learning based resource assignment algorithm...
Aimed at the uneven energy consumption and data redundancy problem of the long-distance ribbon wireless sensor network, a cluster topology control algorithm is proposed based on the topology of ribbon wireless sensor network. The algorithm optimizes the cluster head selection mechanism and effectively guarantees sensor nodes with more residual energy and less communication cost as a cluster head....
Energy has become an important issue in many areas due to increasing energy costs and environmental issues. The Internet is one of the major energy consuming areas. In this paper1, we proposed an energy-aware routing and resource management model for large-scale networks by adapting an SDN (Software Defined Networking) based approach. Controller uses pre-established multi-paths (PMPs) and perform...
Mobile ad hoc networks are energy-constrained networks, nodes in these networks are usually mobile and they are typically implemented in the specific areas where electrical power source is not available. Thus, the operations of these nodes must only rely on battery power or other exhaustible sources of energy. In addition, most of power in each node is required for communication with other nodes or...
The nodes near sink in wireless sensor networks are featured with heavy transmission loads, so these performance bottleneck nodes are prone to running out of energy early with shortened network lifetime. Routing tactic plays important role on transmission performance and energy consumption of network. In this paper, we enumerate typical source routing tactics in Grid topology, include 1) Random Equal...
As the technology sizes of integrated circuits (ICs) scale down rapidly, current transistor densities on chips dramatically increase. While nanometer feature sizes allow denser chip designs in each technology generation, fabricated ICs become more susceptible to wear-outs, causing operation failure. Even a single link failure within an on-chip fabric can halt communication between application blocks,...
The current classic topology contr ol algorithm based on power control class cannot be effective in balancing the network node energy consumption. This defect involves two factors: communication energy consumption between nodes and the node residual energy, which leads to the establishment of communication link cost model. A kind of topology contr ol algorithm is proposed based on the initiative to...
Energy saving in the Internet has become important since the massive new applications are increasing tremendously, along with their energy consumption. In this paper we propose an energy efficient algorithm based on multi-topology routing. Since traffic flow dynamically changed in actual IP network scenarios, the proposed algorithm has to adapt the network energy consumption to daily traffic scenarios...
With the rapid proliferation of data centers, their energy consumption and green house gas emissions have significantly increased. Some efforts have been made to control and lower energy consumption of data centers such as proportional energy consuming hardware, dynamic provisioning and virtual-ization machine techniques. However, it is still common that many servers and network resources are often...
Energy consumption represents a key element in the Wireless Sensor Networks (WSNs) design. Several factors can cause energy over consumption such as mobility, node position (relay or gateway), retransmissions... The network topology can also be a major cause of energy waste: a transmission in 1-hop requires a high energy, a transmission in K-hops requires a lower energy, even though, it can damage...
This paper proposes a tiled chip multiprocessor (CMP) architecture built around an all-optical reconfigurable network, thought to significantly reduce path-setup latency and energy consumption. We propose a novel optical path-setup procedure that is able to configure multiple optical switches simultaneously. Our architecture uses a simple ring-based path-setup network for assisting an optical folded...
A multi-frame Neighbor Discovery Protocol over a DTN network with RFID Devices is proposed. This protocol is based on a Sift-distribution (s-Persistent) in order to differentiate the access probability to slots among RFID devices. Moreover, our approach has been considered in a mono-frame and multi-frame scenario. Our s-Persistent approach is applied in a simulated test and in a real test-bed in order...
We consider the problem of designing content-caching strategies for the energy-efficient delivery of content such as video, over an internet-style network. We propose a method for the design of decentralized caching strategies that can adapt to real-time changes in regional content popularity. This design method is based on a recently proposed reduced consensus-optimization scheme wherein a number...
Average consensus algorithms are an essential tool in wireless sensor networks for multiple estimation tasks, being the convergence time and the energy consumption of these algorithms critical for their usability. Most existing work in the related literature focuses on improving these two parameters, assuming generally unicast communications, which are neither realistic nor efficient given the wireless...
Nodes in ad hoc networks rely on batteries with limited capacity. As result, this imposes constraints on the network lifetime. In order to maximize the network lifetime, routing protocols should deliver traffic in a way that the energy consumption is minimized. This paper discusses the problem of energy saving in QoS multicast routing of ad hoc wireless networks. Our goal is to find a network topology...
The limited capacity of batteries of nodes imposes a constraint on ad hoc networks. Thus, energy efficiency is critical to prolong the network lifetime. Network traffic should be routed such that the energy consumption is minimized. In this paper, we discuss the energy-efficient multicast problem in ad hoc networks with the respect of delay. Multicast routing deals with finding a multicast tree, which...

In certain scenarios, vehicular speeds and locations can be measured with a high degree of accuracy, and this information can be exploited to reduce the energy consumption of base stations. This paper considers...
In low-power and lossy wireless networks, message delivery could be jeopardized by factors such as channel conditions, noise, interference etc. This can lead to communication retransmissions, resulting in significant energy depletion and consequently consumes limited on-node energy resources. This paper elaborates on a two-pronged approach to improve energy efficiency and reliability of communications:...
Due to the in-network caching capability, Content-Centric Networking (CCN) has emerged as one of the most promising architectures for the diffusion of contents over the Internet. In this paper, we propose an energy-efficient distributed in-network caching scheme for CCN. In the proposed scheme, each content router only needs locally available information to make caching decisions considering both...
