This paper presents the issues related to efficient transmission of encoded video (such as H.264) over wireless links using the TFRC protocol. It proposes a novel mechanism that utilizes cross-layer approaches for adaptation of the power transmission level of the sender and feedback information regarding the wireless connection status from the receiver for improved transmission statistics and therefore...
Wireless sensor networks consisting of spatially distributed autonomous devices required to survive in unprotected environments. They are always susceptible to attack by malicious behavior of its routers (nodes) or external enemy nodes which could negatively affect secured routing and QoS and hence, vital wireless multimedia applications. In recent times, a lot of specific severe attacks have been...
The following topics are dealt with: network design; ad hoc mobile network; network protocol; Web service; multimedia service; cellular wireless network; broadband wireless network; Internet technology; RFID; wireless sensor network; signal processing; data communication; data networking; network management; information theory; OFDM wireless system and MIMO system.
Cross-layering is an innovative concept in ad hoc networks for efficient multimedia transmissions in terms of providing better QoS (Quality of Service) support over a capacity-limited wireless channel. Many cross-layer proposals are already developed. They diverge in the way the sharing cross-layer concept is implemented and the type of performance gain they recommend. We propose a new cross-layer...
