The tremendous growth of machine-tomachine (M2M) applications has been a great attractor to cellularnetwork operators to provide machine-type communication services. One of the important challenges for cellular systems supporting M2M terminals is coverage, because terminals can be located in spaces in buildings and structures suffering from significant penetration losses. Since these terminals are also often stationary, […]
It has been shown that high-frequency (HF) band power line communication (PLC), that is, the HomePlug 1.0 specification, is feasible for a low-voltage direct current (LVDC) smart grid (SG) system, where power electronics and low-voltage DC are applied to the electricity distribution. In this paper, the applicability of the latest HomePlug specification, Green PHY (GP), […]
In this paper, we investigate the end-to-end performance of dual-hop proactive decode-and-forward relaying networks with Nth best relay selection in the presence of two practical deleterious effects: i) hardware impairment and ii) co-channel interference. In particular, we derive new exact and asymptotic closed-form expressions for the outage probability and average channel capacity of Nth best partial and […]
In practical large-scale distributed storage systems, node failures are unavoidable. It is therefore desirable to quickly recreate the failed nodes in order to maintain the system integrity. In this letter, we consider a family of erasure codes that provide uncoded repair, where the failed node is regenerated by transfer of data without extra arithmetic operations. […]
SoC (System on chip) technology has rapidly developed in recent years, stimulating emerging research areas such as investigating the efficacy of wireless network interconnection within a single chip or between multiple chips. However the design of the on-chip antenna faces the challenge of obtaining high radiation efficiency and transmission gain due to conductive loss of the silicon […]
Demand response (DR) used in smart grid (SG) can enhance the reliability of the power system as well as reduce the energy costs for customers. One of the major consumers of electrical energy is industry. In this study, we develop a hardware-in-the-loop (HIL) simulator to demonstrate how to practically implement DR in industrial facilities. The […]
Outdoor optical fiber cabinets are generally installed along roadsides where environmental conditions, such as sun exposure, rain, and dust, can cause damage to the cabinets. Furthermore, high temperatures and unexpected impacts that cause cabinet deformation may damage the networkequipment inside the cabinets, affecting the quality of communications. This paper developed an optical fiber sensing system for […]
Routing of data packets is one of the important process in the internet. A routing protocol specifies the method of communication among routers used in the inter connection of networks. There are number of routing protocols which have application on the internet like OSPF, RIP, EIGRP, OPNET, IGRP, etc. Every protocol has its own feature of […]
Low-energy critical infrastructure monitoring (LECIM) applications are rapidly increasing. A communication protocol developed to fulfill the LECIM requirements is the novel IEEE 802.15.4k standard. In this paper, we study the impact of priority channel access (PCA), a feature defined for high priority message transmissions in the IEEE 802.15.4k standard, in LECIM DSSS physical layer (PHY). […]
Dynamic spectrum access (DSA) is a promising technology to alleviate the exhaustion of spectral resources. To realize DSA, new technologies that enable fast discovery of the unused spectrum along with efficient spectrum management must be developed. In this paper, we propose a novel scanning algorithm and access etiquette to provide secondary devices differentiated spectrum access […]
