In Ad Hoc technology, a mobile node is characterized by a limited battery power. Therefore, the energy consumption becomes an important challenge that must be taken into account when designing a new Ad Hoc routing protocol. An efficient routing protocol should also consider a high level of Quality of Service (QoS) such as the end-to-end delay and the bandwidth as the applications do not have the same...
Ad hoc wireless networks are influence embarrassed because nodes function through restricted battery energy. Therefore, Energy expenditure is central propose of new ad hoc routing protocols. To propose such protocols we contain to give the impression of being missing from the conventional minimum hop routing schemes. Moreover, limited-energy property makes together nodes and network lifetime surrounded...
Wireless multimedia sensor networks (WMSNs) is one of the hotest topic nowadays which attracts more and more researchers as being an interdisciplinary research interest. Its cost decreases continously due to advances in micro-electromechanical systems, and the proliferation and progression of wireless communications. However, the transmission of multimedia information must satisfy QoS criteria which...
WiMAX, the acronym for Worldwide Interoperability for Microwave Access is a set of technical standards based on IEEE 802.16 standard. It provides an internet connection to broadband coverage area of several kilometers in radius, it's an adequate response to some rural or inaccessible areas. Unlike DSL (Digital Subscriber Line) or other wired technology, WiMAX uses radio waves and can provide point-to-multipoint...
Motivated by the increasing demand for multimedia services in the internet broadband networks, WiMAX (Worldwide Interoperability for Microwave Access) technology has emerged as a competitive alternative to wired networks broadband. WiMAX is used today as a method of transmission and high-speed internet access, covering a wide geographical area. Unlike DSL (Digital Subscriber Line) or other wired technology...
In wireless ad hoc networks such as Vehicular Ad Hoc Networks (VANET), limited coverage of WiFi and high mobility of the nodes generate frequent topology changes. Therefore Quality of Service (QoS) support becomes an essential aspect. In this work we have identified the need for QoS improvement in VANETs. Survey of related work depicts that, an efficient routing strategy plays a crucial role, to improve...
The idea of converging voice and data into a best-effort service network, such as the Internet, has rapidly developed the need to effectively define the mechanisms for achieving preferential handling of traffic. This sense of QoS assurance has increased due to the enormous growth of users accessing networks, different types of traffic competing for available bandwidth and multiple services running...
