Virtual Vehicles Manager: a java virtual reality environment for distributed multi vehicles dynamics control and simulation

2007

This paper describes a lightweight, full portable software environment for development, simulation and control of vehicles. All the software is developed in Java so there are many advantages as portability, multithreading distribution etc. This environment simulates the vehicles integrating their non-linear differential equation systems. The equation systems can easily be modified changing that representation class so it is easy to manage different vehicles. The scenario is displayed as a 3D virtual reality environment in which all the objects are rendered using a combination of 3 d primitive. It is also possible the use of pre-built 3 d objects loaded from files in 3 ds format. The softwar…

Is TCP Packet Reordering Always Harmful?

2004

IP networks do not provide any guarantee that packets belonging to the same flow are delivered in the correct order. Out-of-order reception of packets was commonly considered due to pathological network conditions (such as link failures, etc.). However, it has been shown that packet reordering is a phenomenon which occurs even in normal network operation, due to a number of link-level and/or router-level implementation features, such as local parallelism and load balancing. Packet reordering is intuitively considered as a negative phenomenon, which may severely affect TCP traffic performance since it is expected to cause inefficient usage of the available link bandwidth and is expected to i…

Performance Evaluation of CANIT Algorithm in Presence of Congestion Losses

2001

In this paper, we analize by queuing-simulation CANIT (Congestion Avoidance with Normalized Interval of Time) algorithm performances in presence of congestion losses. In a former work [3], we proposed the algorithm (CANIT) for TCP (Transmission Control Protocol) congestion avoidance phase in order to improve fairness during this phase, and we showed that using CANIT algorithm in an environment without loss, instead of standard congestion avoidance algorithm improves both congestion avoidance fairness and bandwith utilization for long RTT connections. In this paper, we consider congestion losses and show that the fairness as well as the bandwith utilization are more efficient when using CANI…

An analytical model of a new packet marking algorithm for TCP flows

2005

In Differentiated Services networks, packets may receive a different treatment according to their Differentiateo Services Code Point (DSCP) label. As a consequence, packet marking schemes can also be devised to differentiate packets belonging to a same TCP flow, with the goal of improving the performance experienced. This paper presents an analytical model for an adaptive packet marking scheme proposed in our previous work. The model combines three specific sub-models aimed at describing (i) the TCP sources aggregate, (ii) the marker, and (iii) the network status. Preliminary simulation results show quite accurate predictions for throughput and average queue occupancy. Besides, the research…

Specific protocol (SENSLOG) over TCP/IP for sensors applications

2005

The objective is to obtain an embedded system using a microcontroller that will communicate with other devices over a specific protocol (SENSLOG) over TCP/IP for sensors applications. The protocol has been designed for this application, but the commands are generic. They can be used for any type of sensing. We must take into account that this program will run in a microcontroller and it will communicate with another program running in a PC. The protocol is based on commands, like SMTP. From the PC we will send commands to the microcontroller to do specific tasks, and if it is necessary, the microcontroller will answer to the PC. Some of the functions designed for this protocol are: to contr…
