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 access control protocol (MMAC) for

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. The

The aim of this report is to research wireless antennas and differences between them. Antennas are included 3 types: omnidirectional‚ semi-directional‚ and highly-directional. Any antenna has three fundamental properties: gain‚ directional and polarization. Omnidirectional Antennas. We can use this antenna in a: point-multipoint link‚ warehouse‚ hotspot‚ trade show‚ airport. The omnidirectional antennas transmit a signal in all directions‚ it is known dipole ("non-directional") antenna. The

SECURITY OF WIRELESS COMMUNICATIONS Introduction Wireless devices‚ like all technologies that provide external access to corporate networks‚ present security challenges. With wireless standards and practices still rapidly evolving‚ it is important to understand the strengths and limitations of available technologies in order to implement a secure solution. Extending current security policies to encompass wireless devices requires an understanding of the security features of both wireless devices and

Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio. With radio waves distances can be short‚ such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of fixed‚ mobile‚ and portable applications‚ including two-way radios‚ cellular telephones‚ personal digital assistants
Premium Bluetooth Wireless Wireless network
Introduction Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or the entire communication path. The first wireless transmitters went on the air in the early 20th century using radiotelegraphy (Morse code). Later‚ as modulation made it possible to transmit voices and music via wireless‚ the medium came to be called "radio." With the advent of television‚ fax‚ data communication‚ and the effective use of
