Bluetooth is a wireless personal area network. This type of networks is widely used for image communication. This paper presents a study for the transmission of images over mobile Bluetooth networks. It presents a novel chaotic interleaving scheme for this purpose. In this scheme, the chaotic Baker map is used for bit interleaving and enhanced data rate packets are used for data transmission. In the...
With increasing the applications fields of low-power short range wireless communication, especially Bluetooth, the most of these applications need transmitting image. This paper proposes improving the colored JPEG image transmission over mobile Bluetooth network using Enhanced Data Rate (EDR) packets with the 2DH3 and 2DM3 EDR Asynchronous Connectionless (ACL) packets. It proposes using efficient...
New generations of Search Engines aim to focus on user's needs rather than user's queries. This means personalization of the returned results to suit the user needs and expectations. In this paper, we believe that in order to enhance the personalization process, we have to enhance the data that used as an input to the personalization algorithm. According to this work, we will analyze the web structure...
The IEEE 802.16 standard which has emerged as a broadband wireless access technology, promises to deliver high data rates over large areas to a large number of users in the near future. We present a simple analytical method for VoIP capacity estimation in IEEE 802.16e mobile WiMAX networks. Various overheads that impact the capacity are explained and methods to reduce these overheads are also presented...
The IEEE 802.16 standard defines wireless broadband access technology called Worldwide Interoperability for Microwave Access (commonly called fixed WiMAX). WiMAX introduces several interesting advantages including variable and high data rate, last mile wireless access, point to multipoint communication, large frequency range, and Quality of Service (QoS) for various types of applications. IEEE 802...
