In wireless multimedia sensor networks (WMSNs) a sensor node may have different types of sensor which gather different kinds of data. To support quality of service (QoS) requirements for multimedia applications having a reliable and fair transport protocol is necessary. One of the main objectives of the transport layer in WMSNs is congestion control. We observe that the information provided may...

BACKGROUND Despite sensational news reports, few studies have quantified the rates of poor driving performance among older drivers and the predictors of poor performance. We determined the rate of running red traffic lights among older drivers and the relationship of failure to stop to measures of vision and cognition. METHODS Multiple measures of vision and cognition were collected at the ba...

An ad hoc network of vehicles (VANET) consists of vehicles that exchange information via radio in order to improve road safety, traffic management and do better distribution of traffic load in time and space. Along with this it allows Internet access for passengers and users of vehicles. A significant characteristic while studying VANETs is the requirement of having a mobility model that gives ...

Annually, more than 1 million people were killed in road traffic accidents worldwide every year and an uncounted number were severe injured. In 2012 fatal injuries caused by road traffic accidents are under the top ten lists of causes of death in the world. It´s expected that in the near future road traffic accidents become one of the main causes of death in the world. Most of these fatal injur...

Currently, cognitive radio solves the problem of spectral congestion by load sharing wireless traffic across different licensed spectrum bands. However, it is thought that a more powerful approach would be to load share the traffic across both fixed and wireless access networks. It is thought that such an approach will be able to prevent spectral congestion for the foreseeable future for a sign...

This paper evaluates the concept of virtual path (VP) policing as an alternative to virtual channel (VC) policing in an Asynchronous Transfer Mode (ATM) network. The Usage Parameter Control (UPC) function includes a peak rate and a sustainable rate policer. Both policers are implemented based on the Leaky Bucket algorithm defined by the ATM Forum. We implement VC and VP policers in parallel in ...

Integrated Network-Based Ohio University Network Detective Service (INBOUNDS) is a network based intrusion detection system being developed at Ohio University. The Anomalous Network-Traffic Detection with Self Organizing Maps (ANDSOM) module for INBOUNDS detects anomalous network traffic based on the Self-Organizing Map algorithm. Each network connection is characterized by six parameters and s...

We propose a new multifractal traffic model for network traffic. The model is a combination of a multiplicative cascade with an independent lognormal process. We show that the model has all the important properties observed in data traffic including LRD, multifractality and lognormality. We also demonstrate that the model is flexible enough to capture the complete multifractal characteristics o...

Cloud is in the air. More and More companies and personals are connecting to cloud with so many variety of offering provided by the companies. The cloud services are based on Internet i.e. TCP/IP. The paper discusses limitations of one of the main existing network management protocol i.e. Simple Network Management Protocol (SNMP) with respect to the current network conditions. The network traff...
