Light Routing Algorithm for Utility Networks
No full textIn several application domains like Ambient Assisted Living systems or in users accounting services, specific network protocols are called for to interconnect different data processing devices having limited processing power and energy [1]. Typically, the interconnections are accomplished through dedicated cables or as power lines, or through wireless, but even if the cables are fully utilized, few protocols have been drawn up or planned to optimize communication among a high number of devices. One reason for the limited development of these protocols lies in the difficulty of reconciling the efficiency and efficacy of a protocol with scarce power computing of the nodes. This article will propose an efficient algorithm for routing applicable to networks with many nodes and with interferences typically present in power lines, and with low management overhead. The algorithm guarantees reliability and transparent distribution over large networks like accounting networks for the distribution of water, gas and tele-heating. Implementation of the protocol can be realized within the European M-Bus
Energy Efficient Light Routing in Utility Network
No full textNowadays, automatic meter reading is an essential technology for customers and providers. The meter communication infrastructure is frequently subject to interference and is composed of nodes with limited memory and processing capability. These limitations make the development of routing protocols a challenging task. We propose a new centralised reliable protocol based on European M-Bus [EN13757] that uses a distributed cache with a master/slave model. This reduces the network overhead while keeping a good throughput. We have validate our protocol by considering a network with white Gaussian noise and binary symmetric channels. The simulation shows a reduced fault while keeping a good throughput and low power consumption
Energy-Efficient Clustering for Wireless Sensor Devices in Internet of Things
No full textA recent study predicted that in 2020 there will be 50 billion devices connected to the Internet. These devices are not only smartphones and tablets, but also things which are able to perform various operations, such as sensing data and actuating on the external environment. With this perspective, WSNs are highly needed in the Internet of Things (IoT) vision. Since WSN nodes are often equipped with batteries, energy-efficient WSNs is an important goal to achieve. In this chapter, we review and compare different energy-efficient clustering protocols for WSNs. We consider WSNs that are composed of heterogeneous wireless sensor devices (i.e., heterogeneous WSNs) but we also take into account protocols that incorporate various IoT devices such as RFID and with energy-harvesting capability. We describe our novel Rotating Energy-Efficient Clustering for Heterogeneous Devices (REECHD). This is a novel clustering protocol for heterogeneous WSNs. REECHD is compared with the state-of-the-art clustering by using simulation

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
