Development of Portable Internet Access Module for Sensor Data Collection

Recently, many researches and development activities on sensor node hardware have been done for the sensor networks. Although well designed for general sensor networks, they are often too heavy and complex for simple applications to be used to access distributed sensor nodes separately and directly over internet. This paper aims to address this issue with a novel approach; by developing a simpler internet access module which collects sensor data for simple applications without platforms support. In this scheme, each sensor node can be easily accessed over internet (wired or wireless) by user. This module is very cheap and easy to be built, and a high performance can be achieved by using a hardware TCP/IP chip.
