Abstract ”
Developing open mobile robot has been a hot topic in AI area. In an open system, a particular component can be easily added and/or replaced. In this paper, a modular and object oriented approach is used to construct an autonomous mobile robot system. IPC (interprocess communication), which is the key mechanism in Linux/Unix operation system, is applied to the robot design. Based on Windows operation system, the robot owns an omnivision, and can finish tasks such as navigation and robot soccer. With a modular design, new compo ....etc

The client server model
Most interprocess communication uses the client server model. These terms refer to the two processes which will be communicating with each other. One of the two processes, the client, connects to the other process, the server, typically to make a request for information. A good analogy is a person who makes a phone call to another person.
Notice that the client needs to know of the existence of and the address of the server, but the server does not need to know the address of (or even the ex ....etc

Definition

Sockets are interfaces that can plug into each other over a network. Once so plugged in, the programs so connected communicate. A server program is exposed via a socket connected to a certain /etc/services port number. A client program can then connect its own socket to the server's socket, at which time the client program's writes to the socket are read as stdin to the server program, and stdout from the server program are read from the client's socket reads.

Before a user process can perform I/O operations, it calls ....etc

Abstract:
Real time systems play a considerable role in our society, and they cover a spectrum from the very simple to the very complex. Examples of current real-time systems include the control of domestic appliances like washing machines and televisions, the control of automobile engines, telecommunication switching systems, military command and control systems. Industrial process control, flight control systems, and space shuttle and aircraft avionics All of these involve gathering data from the environment, processin ....etc

Introduction

-Exchange of data between two or more separate, independent processes/threads.
-Operating systems provide facilities/resources for inter-process communications (IPC), such as message queues, semaphores, and shared memory.
-Distributed computing systems make use of these facilities/resources to provide application programming interface (API) which allows IPC to be programmed at a higher level of abstraction. (e.g., send and receive)
-Distributed computing requires information to be exch ....etc

DCOM Technical Overview
Introduction
Microsoft® Distributed COM (DCOM) extends the Component Object Model
(COM) to support communication among objects on different computers”on
a LAN, a WAN, or even the Internet. With DCOM, your application can be
distributed at locations that make the most sense to your customer and
to the application.
Because DCOM is a seamless evolution of COM, the world's leading
component technology, you can take advantage of your existing
investment in COM-based applic ....etc

1. INTRODUCTION

Satellites have been used for years to provide communication network links. Historically, the use of satellites in the Internet can be divided into two generations. In the first generation, satellites were simply used to provide commodity links (e.g., T1) between countries. Internet Protocol (IP) routers were attached to the page link endpoints to use the links as single-hop alternatives to multiple terrestrial hops. Two characteristics marked these first-generation systems: they had limited bandwidth ....etc

Multicast Routing Algorithms and Protocols

Introduction
In the age of multimedia and high-speed networks, multicast is one of the mechanisms by which the power of the Internet can be further harnessed in an efficient manner. It has been increasingly used by various continuous media applications such as teleconferencing, distance learning, and voice & video transmission.

Compared with unicast and broadcast, multicast can save network bandwidth and make transmission more efficient. In this semin ....etc

Randomized Instruction Set Emulation

Abstract
This topic deals with the security issue facing the modern computer systems.All the systems follow a specific standard to make them compatible and independent.So it is easy for an attacker to hit the vulnerability since he knows the standard that the system follows .Moerover the same attack will be successfull on al ....etc
