Sensors network based on mobile robots

Abstract

This paper describes a sensor network design based on a mobile multi-robot system. System topology is a distributed computing architecture that consists of a PC Server, Local Area Network (LAN) with Wireless Access Points (WAP), a set of Master Mobile Robots with gateway features and a set of Slave Mobile Robots, grouped according to their investigation tasks. The concept of data acquisition control is based on the PC Server general strategy, which is distributed to each Slave Robot via Master Robot. Master Robots fulfill the Gateway function for data transmission through Transmission Control Protocol/Internet Protocol (TCP/IP) and Radio Frequency Communication (RFC) networks using appropriate communication protocol. The functionality of the designed system has been checked on a network with four sensors that measures the temperature gradient around a heat source.
