In delay tolerant networking (DTN), nodes are autonomous and behave in an unpredictable way. Consequently, a control mechanism of topology is necessary. This mechanism should ensure the overall connectivity of the network taking into account nodes’ mobility. In this paper, we study the problem of data routing with an optimal delay in the bundle layer, by exploiting: the clustering, the messages...

Energy efficient routing protocols can potentially reduce the amount of energy consumed in packet forwarding. However, existing literature lacks studies on improving green performance of geocast routings for the Internet of Vehicles. Therefore, this study proposes an energy efficient min delay (EEMD)-based geocast routing protocol to find optimal relay nodes by incorporating energy consumption ...

Predictors of birth weight and birth length were studied using sociodemographic data collected from 2259 women who resided in Funen County, Denmark, and delivered a healthy child during the period 1978-9 at Odense University Hospital. Low birth weight was significantly related to tobacco use in the year of delivery (p less than 0.01), alcohol use during the same period (p less than 0.05), and a...

This paper details the development of an educational and research tool, the Network Performance Application (NPA), which provides real-time network performance measurement through a simulated voice over IP session using live real-time data transmission over packet networks. This application, written in Visual C++ for MS Windows environments, is used to collect Quality of Service (QoS) statistic...

Background: Increasing the complexity in modern radiotherapy techniques have increased the delivery time lowering consequently the treatment efficacy. Through simulating the delivery time delay encountered in such techniques, its’ effect on two cancer cell lines and the compensating doses given to prevent such effect was investigated. Materials and Methods: F10B16 and 4T1 cancer cell line...

We propose a multiple-delivery transport service tailored for graphics and video transported over connections with wireless access. This service operates at the interface between the transport and application layers, balancing the subjective delay and image quality objectives of the application with the low reliability and limited bandwidth of the wireless link. While techniques like forward-er...

Ensuring QoS is the major research dimension in the area of MANET by which reliable transmission of data is ensured. This research focuses in proposing a routing mechanism which ensures QoS through packet scheduling. The proposed routing scheme has contributions three fold. At first, a QoS-aware neighbor node selection mechanism is incorporated in order to meet the transmission delay requiremen...

As depicted in Figure 1, today’s wireless local area networks (WLANs) concurrently support a plethora of user applications with diverse connectivity and Quality of Service (QoS) requirements. Wireless traffic flows contending for resources can degrade performance for one or more of the wireless applications. Delay sensitive applications may face high latency in the presence of competing wireles...

A Wireless Sensor Network (WSN) is a collection of low-cost, low-power and large-scale wireless sensor nodes. Routing protocols are an important topic in WSN. Every sensor node should use a proper mechanism to transmit the generated packets to its destination, usually a base station. In previous works, routing protocols use the global information of the network that causes the redundant packets...
