DESIGN AND IMPLEMENTATION OF EMBEDDED COGNITIVE CONTROLLER FOR INTEGRATING MULTIPLE COMMUNICATION

Abstract

In this project we utilized multiple communication technology interfaces to increase the scale of connectivity and to provide continuous connectivity. We have different nodes that connect using different communication technologies (802.3, 802.11, GSM, DIAL-UP etc). Our goal is to design a system that makes our communication via these technologies selecting the optimum one from one location to other using the above technologies. We would be designing the routing algorithm that can switch between the communication technologies and can find the path to the destination via different communication technologies. Each link or communication technology is assigned a METRIC that‟s computed from the delay of line, MTU, bandwidth, availability, feasibility, cost and vendor assignment. From source to destination there might be many nodes and it is possible that communication between a pair of nodes is via one technology and the other pair uses other technology so it means that data when transferred from source to destination may go through many communication technologies. We created our own algorithm to perform routing among multiple communication technology interfaces. We published a paper on our algorithm in IEEE 2nd ICSTE 2010 Puerto Rico USA. We created simulation of our algorithm in omnet and tested our algorithm under different scenarios. We also created real time environment for testing of our algorithm. We use EmbeddedARM Single Board Computer as a Cognitive Switcher which performs all the routing. We created a control system to monitor complete network. We successfully achieved our goal of increasing scale of connectivity and providing continuous connectivity utilizing multiple communication technologies. We created an algorithm and tested our algorithm using simulation and also tested by creating a real time environment.
