Congestion control is a distributed algorithm to share network bandwidth among competing users on the Internet. In the common case, quick response time for mice traffic (HTTP traffic) is desired when mixed with elephant traffic (FTP traffic). The current approach using loss-based with Additive Increase, Multiplicative Decrease (AIMD) is too greedy and eventually, most of the network bandwidth w...

Mobile Ad Hoc Networks (MANETs) are receiving a significant interest and are becoming very popular in the world of wireless networks and telecommunication. MANETs consist of mobile nodes which can communicate with each other without any infrastructure or centralized administration. In MANETs, the movement of nodes is unpredictable and complex; thus making the routing of the packets challenging....

We describe a statistically customisable solution for Web benchmarking that includes three utilities: an Internet traffic generator for HTTP traffic, an static and dynamic Web pages generator in the Web server that is going to be tested and a performance monitor that reports some performance metrics during the test. The design of the tool is based on the implementation of the most important pro...

background and aim: injuries from traffic accidents are a major public health problem, and the third leading cause of mortality in people aged 1 to 40 years. each year 31.8 persons per hundred thousands of iranians are killed in car accidents. neighboring of north khorasan province with razavi khorasan, a province with a lot of pilgrims caused a large number of passengers travel via north khora...

We evaluate the capabilities of MANETs in supporting multiple, simultaneous HTTP and multimedia streaming flows. The HTTP traffic is produced by several Web servers, each responding to a series of concurrent requests from multiple Web clients, and multimedia traffic is modelled as a variable bit-rate stream consisting of UDP packets. To see the impact of a routing protocol, we consider two on-d...

The simulation of realistic networks is an important aspect in the development of new protocols or algorithms for communication networks. The traditional approach for such a simulation is to connect a certain amount of sources to network nodes and to measure the link load, end-to-end delay etc. in the simulation in order to evaluate the performance of the network. Network providers have a diffe...

Over the last five years, several trends have changed the landscape of the World Wide Web, forming the new “Web 2.0”. The advent of user generated content (blogs and wikis), the popularity of multimedia (e. g., YouTube and MySpace), and the penetration of Google’s services (maps, mail, etc.) are commonly noticeable. In particular, the recent popularity of Online Social Networks (OSNs, e. g., Fa...

In this paper, we analyze the queueing behaviour of wavelength division multiplexing (WDM) Internet router employing partial buffer sharing (PBS) mechanism with self-similar traffic input. In view of WDM technology in networking, each output port of the router is modelled as multi-server queueing system. To guarantee the quality of service (QoS) in Broadband integrated services digital network ...

Weather is known to have a strong effect on traffic volumes. In this paper, we suggest a spatial approach to the modelling of traffic volumes. The relationship between weather variables and traffic volume is first modelled at a global level in a regional city centre in Finland. As strong a spatial dependency is found between the variables in the model, spatial variation is incorporated into the...
