WiMAX (Worldwide interoperability for Microwave Access) cellular networks with Multi-hop Relays (MRs), standardized as IEEE 802.16j networks, have been proposed for the improvement of overall throughput by providing last mile high speed broadband service to the users. The scheduling algorithm at Base Station (BS) plays a vital role in optimal resource allocation. In queue aware ...

One of the most important multimedia applications is Internet protocol TV (IPTV) for next-generation networks. IPTV provides triple-play services that require high-speed access networks with the functions of multicasting and Quality-of-Service (QoS) guarantees. Among 4G mobile access networks are regarded as among the best solutions to meet higher bandwidth demands. In this paper, they propose ...

Wireless sensor network is composed of hundreds and thousands of small wireless sensor nodes which collect information by sensing the physical environment. The sensed data is processed and communicated to other sensor nodes and finally to base station. So energy efficient routing to final destination called base station is ongoing current requirement in wireless sensor ...

Advancements in WSN have led to the wide applicability of sensor network in various fields. WSNs basic classification is reactive and proactive network. Reactive networks responds to the very immediate changes in its environment in required parameters of interest, as opposed to the proactive network, due to continuous sensing nature of WSN. To make it ...

Steganography is a technology used since years for the communication of messages secretly. These secret messages are put inside honest carriers. Carriers can be digital images, audio files, video files and so on. The limitation in sending concealed longer messages has been overcoming by the inclusion of video files as carriers. Popular internet services such ...

A Mobile Ad-hoc NETwork (MANET) is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. When designing mobile ad hoc networks, several interesting and difficult problems arise because of the shared nature of the wireless medium, limited transmission power (range) of wireless devices, node mobility and battery limitations. This paper ...

The topology of Mobile Ad hoc NETworks (MANETs) change dynamically with time. Connected Dominating Sets (CDSs) are considered to be an effective topology for network-wide broadcasts in MANETs as only the nodes that are part of the CDS need to broadcast the message and the rest of the nodes merely receives the message. However, with ...

Cloud computing is the current IT buzzword synonymous with outsourced data center management and agile solution architecture. It has the potential to improve scalability of large enterprise network delivery of services and the capability to revolutionize how data is delivered as a service. At its core, cloud computing is not a new technology but rather ...

Coordinated Multi-Point transmission and reception (CoMP) is introduced in LTE-A to mitigate co-channel interference and improve the cell-edge user experience. In this paper, the authors propose a joint transmission scheme for LTE-CoMP and they enhance the performance of CoMP with two techniques: 1- dynamic MIMO cell selection and 2- closed loop MIMO with global precoding ...

Ubiquitous Computing uses mobile phones or tiny devices for application development with sensors embedded in mobile phones. The information generated by these devices is a big task in collection and storage. For further, the data transmission to the intended destination is delay tolerant. In this paper, the authors made an attempt to propose a new ...
