Traditional automatic repeat request (ARQ) protocols are channel unaware. That is, they react to channel errors by simply retransmitting erroneous packets and do not proactively decide whether or not to transmit a packet in a given slot based on past channel conditions. Clearly, ARQ protocols operating in this mode are not energy efficient. For example, continuously retransmitting erroneous pac...

Wireless mesh network is an advanced form of wireless network. A wireless mesh network provides a better solution to problems that often arise in cellular and WLAN. Wireless mesh networks (WMNs) are receiving increasing demand as an effective solution to deploy ISP’s wireless last mile access, such as wireless enterprise backbone networks and other applications. Wireless mesh networks (WMNs) pr...

Wireless broadcasting system is of major two types namely push-based and pull-based. Extensible Markup Language (XML) is used to represent any information due to its inherent potential features such as scalable, self-describing, etc. Hence XML is chosen as standard for information dissemination in wireless broadcasting systems. Push based system periodically broadcasts XML data over the wireles...

In Mobile Ad Hoc Networks (MANETs), wireless mobile devices are designed to work in co-operative manner. These devices are connected via wireless link to communicate with each other. The node mobility, channel collision and abnormal channel conditions are the reasons for the occurrence of data transmission failure in MANET. Even though several routing schemes are available to handle these probl...

The proportional loss rate differentiation PLD model was proposed to provide controllable and predictable loss rate for different classes of wired network connections. However, these algorithms cannot be directly applied to wireless networks, because of the location-dependent and time-varying wireless channel capacity. This paper proposes a novel packet dropper for fuzzy controlling of the prop...

Wireless Networking is one of the fastest growing areas in the network industry today. Wireless Local Area Networks (WLANs) are gaining special interest as they provide flexibility of location along with low infrastructural and maintenance costs. The hidden terminal problem is unique to wireless networks that decrease the performance of the network. In this paper we propose a new MAC protocol t...

Wireless video streaming is a challenging task due to limited bandwidth and error-prone characteristics of the wireless channels. In order to ensure high quality wireless video streaming, error control techniques such as forward error correction (FEC) is needed. It is well-known that, in mobile radio channels, errors are not limited to single bit errors but tend to occur in bursts. In order to ...
