Wireless sensor networks are often located in areas where access to them is difficult or dangerous. Today, in wireless sensor networks, cluster-based routing protocols by dividing sensor nodes into distinct clusters and selecting local head-clusters to combine and send information of each cluster to the base station and balanced energy consumption by network nodes, get the best performance ...

This paper describes air interface standards for wireless local area network (LAN), wireless metropolitan area network (MAN), and wireless personal area network (PAN) technology being developed within the IEEE 802 LAN MAN Standards Committee of the Institute of Electrical and Electronics Engineers, Inc. (IEEE). 1 U.S. Government work, not subject to U.S. Copyright. IEEE C802.16-03/03

This paper evaluates the Total Vector Error of an estimated Phasor as define in IEEE C37.118 standard within different medium access in Local Area Networks (LAN). Three different LAN models (CSMA/CD, CSMA/AMP and Switched Ethernet) are evaluated. The Total Vector Error of the estimated Phasor has been evaluated for the effect of Nodes Number under the standardized network Band-width values defi...

This chapter provides the reader with the ability to have a general appreciation of hardware and software, and data communication hardware and software in particular. It will raise an awareness of the need for networks to conform to international standards and for strategies to be developed to allow this transmission to be made. The importance and use of Local Area Networks (LANs) and Wide Area...

This paper presents a new mathematical framework of a Scalable Mobility Model (SMM) to characterise user movement behaviour, which can be applied to a wide number of network scenarios ranging from Local Area Networks (LAN) to Wide Area Networks (WAN). The core technique to describe the spatial and temporal behaviour of mobile users is the introduction of a novel concept referred to as Pole of G...

The paper presents the results of a performance analysis of mobile agents in a distributed network environment. Analytical models are developed and used to compare the performance of carrying out a simple management function with Mobile Agents (MA) or SNMP (Simple NetworkManagement Protocol). We examine how delay is affected by the size of the management domain and how each method behaves in bo...

State estimation in the energy management center of active distribution networks has attracted many attentions. Considering an increase in complexity and real-time management of active distribution networks and knowing the network information at each time instant are necessary. This article presents a two-step multi-area state estimation method in balanced active distribution networks. The prop...

This paper discusses the state of the art in networking, and explains the way existing networks can support tele-education applications. Chapter 1 identifies which tele-education parameters have the biggest impact upon the underlying network, and proposes a classification of teleeducation applications. Chapter 2 discusses the various networks that are used for tele-education purposes: Local Are...

This paper analyzes the SIP-based mobility management behavior within a heterogeneous network interconnecting IEEE 802.11-based wireless local area network (WLAN) and IEEE 802.16-based wireless metropolitan area network (WMAN). Our work focuses on signaling processes, during handoff between 802.11 and 802.16 networks. Particularly, the MAC layer technologies of 802.11 and 802.16 are examined in...
