An Ad-hoc network has a Provision of Quality of Service (QoS) to support many applications like digital and multimedia applications. However, one of the challenging tasks in Ad-hoc Network (MANET &VANET) is Quality of Service (QoS) which is determined by numerous parameters such as bandwidth and delay constraints, varying channel conditions, power limitations, node mobility, dynamic topology, p...

An Ad-hoc network has a Provision of Quality of Service(QoS) to support multimedia applications. One of the most challenging tasks in Ad-hoc Network(MANET &VANET) is Quality of Service (QoS) which is determined by numerous parameters such as bandwidth and delay constraints, varying channel conditions, power limitations, node mobility,dynamic topology, packet delivery ratio, end-to-end delay and...

The underwater acoustic channel features long and variable propagation delay, high bit error rate and limited bandwidth. Moreover, underwater mobile networks consisting of Autonomous Underwater Vehicles (AUVs) for surveillance and monitoring applications often suffer from intermittent connectivity as nodes move around the area of operations. Therefore, this scenario is appropriately modeled as ...

In the era of big data, the Internet engineering community is searching for solutions to alleviate the issues caused by the constantly increasing data traffic. In this paper, we attempt to revive the sneakernet paradigm as a possible solution for non-real-time bulk data transfers. We propose a sample network architecture that takes advantage of the existing worldwide airline infrastructure, and...

A vehicular network topology is very dynamic compared to traditional mobile ad hoc network because of the movement and speed of the vehicles. Thus, a vehicular network is always partitioned due to this reason, especially if the vehicle density is low. In this situation where a direct end-to-end path between source and destination can be considered as non-existent, a regular ad hoc routing proto...

 ABSTRACT Background: As any delay in the onset of milk production and ejection in the first few days after delivery can cause breast-feeding failure, this study has been done to determine factors that may affect the onset time of lactation in vaginal and cesarean section deliveries with and without labor pain (elective). Methods: 300 partUJient mothers selected from two private and university ...

Vehicular communication systems facilitate communication devices for exchange of information among vehicles and between vehicles and roadside equipment. These systems are used to provide a myriad of services ranging from traffic safety application to convenience applications for drivers and passengers. In this paper, we focus on the design of communication protocols for vehicular access network...

Delay tolerant networks (DTNs) rely on the mobility of nodes and sequences of their contacts to compensate for lack of continuous connectivity and thus enable messages to be delivered from end to end in a “store-carry-forward” way, where multiple relay nodes are usually employed in the message delivery process. In this paper, we focus on such relay cooperation and analytically explore its impac...

With the proliferation of mobile communications, new kinds of network architectures are being defined over the existing static one. Delay-Tolerant Networks (DTN) come to fill in a gap in the existing networking technology: they provide support for communication between peers when there is no end-to-end path available between them. Message forwarding in DTNs can be handled in many ways. In this ...
