REMOTELY RECONFIGURABLE, SECURE WIRELESS MESH NETWORK FOR BIDIRECTIONAL DATA COMMUNICATION

Abstract

In today’s Electronic world, there are many devices which connect to one another as well to computer in a variety of ways: A cable connects a computer's processing unit to a display, a data cable and a docking cradle connect a personal digital assistant (PDA) or a cellular phone to a computer, radio waves connect a cordless phone to its base unit, an infrared beam connects a remote control to a television. The elaborate array of connectors among electronic devices cries out for a better solution.

In this fast growing technology world, wireless data transferring in a desired format is essential. Data integrity, data security, cost of hardware and software, and system’s power management capacity is of prime importance for our data acquisition application. With the increasing use of data loggers to collect information in industrial and environmental monitoring applications, has come a corresponding increase in the use of wireless technology to retrieve the information. Secure and remotely reconfigurable data acquisition system having several nodes communicating in a bidirectional way is essential for the most industrial/commercial and household applications. Although, improved range of wireless system can be obtained at increased price. Limited range and high cost of available wireless data acquisition system inhibits many potential applications.

This project is to develop a low cost, reconfigurable, secure, bidirectional wireless mesh network for industrial/commercial and household applications. A low cost and reconfigurable wireless mesh network will contribute significantly in to currently available communications infrastructure. This wireless mesh network system would provide a solution for customizing a bidirectional sensor network. The wireless mesh network will also provide wireless inventory solution in a large warehouse and could facilitate many other similar applications. This wireless system has features that could be used to transmit requests or commands out the serial port to control or query a desired sensor or an instrument directly. The system shall be fully customizable, network-able and easily configurable.

This type of reconfigurable and secure wireless mesh network system will significantly reduce installation cost, improving data security, data integrity and power consumption. The wireless mesh network system will not only offer potential cost saving, but they can reduce system downtime propel by integrated and programmable power management protocol. This system will enhance both network intelligence and system’s overall functional capabilities, as well.

Introduction

A wireless mesh network (WMN) is defined as a network with nodes having connections to the several other network nodes. In a full mesh network, every node has a connection to every other node. In a partial mesh network, every node isn't connected to every other node; instead, only a
