MMAC: A Mobility-Adaptive‚ Collision-Free MAC Protocol for Wireless Sensor Networks Muneeb Ali‚ Tashfeen Suleman‚ and Zartash Afzal Uzmi Computer Science Department‚ LUMS {muneeb‚tashfeens‚zartash}@lums.edu.pk Abstract Mobility in wireless sensor networks poses unique challenges to the medium access control (MAC) protocol design. Previous MAC protocols for sensor networks assume static sensor nodes and focus on energyefficiency. In this paper‚ we present a mobilityadaptive‚ collision-free medium

CHAPTER 15 Wide-Area Wireless Networks (WANs) — GSM Evolution 15.1 Introduction Third-generation (3G) wireless systems [2‚3‚9] offer access to services anywhere from a single terminal; the old boundaries between telephony‚ information‚ and entertainment services are disappearing. Mobility is built into many of the services currently considered as fixed‚ especially in such areas as high speed access to the Internet‚ entertainment‚ information‚ and electronic commerce (e-commerce) services.

line 1. INTRODUCTION Wireless ad hoc networks have emerged to support applications‚ in which it is required/desired to have wireless variety of devices without relying on communications among a any infrastructure or central management. In ad hoc networks‚ wireless devices‚ simply called nodes‚ have limited transmission range. Therefore‚ each node can directly communicate with only those within its transmission range (i.e.‚ its neighbours) and requires other nodes to act as routers in

function is research in the field of snow and avalanches to provide avalanche control measures and forecasting support to Armed forces. SASE registered steady growth from 1971 to 1977 and role of SASE was enlarged with the constitution of Advisory Committee. Avalanche forecasting‚ Artificial triggering‚ Structural control and generating awareness formed part of activities of SASE. A vast network of high altitude observatories was also established. Planned reconnaissance of avalanche prone axes in J&K

Introduction Wireless network is indicated to a telecommunication network whose interconnections between nodes are implemented without the use of wires‚ such a computer network. Nowadays‚ wireless network has become the important thing in telecommunication. This sort of technology has been used for over a century and remains synonymous with radio. In 19th century‚ Guglielmo Marconi invented a radio and made his made his mark in the world of wireless technology. At that moment‚ Marconi was about

“Wireless Network” A wireless network is any type of computer network that uses wireless data connections for connecting network nodes. Wireless networking is a method by which homes‚ telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building‚ or as a connection between various equipment locations.[1] Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation

Wireless Network A wireless network‚ as its name would suggest‚ is a network of computers and computer peripherals that are connected to each other without wires. This enables ease of communication‚ especially for mobile computing platforms. Further‚ there are a number of other advantages to a wireless network that make them increasingly common in both the workplace and at home. Nearly all wireless networks in the world work on a standard set up by the Institute of Electrical and Electronics
