A new gateway node for wireless sensor network applications

Abstract

Wireless sensor network based applications have gained a significant importance in recent years. However, it creates problems when sending the detected data over distant stations even though establishment of sensor networks by means of ZigBee communication modules as the communication range of these modules are limited. For this reason, in this study, design of a gateway node which can be used in the sensor network applications was developed. The gateway node developed consists of a CC2530 ZigBee Module, an MSP430G2553 ultra low power microcontroller and a SIM900 GSM/GPRS module. As a result of this node, the sudden changes can be sent as data packets (SMS), also, the data can easily be monitored on web based and mobile platforms. It is anticipated that the study will be useful for the researchers conducting sensor network applications.   Key words: Wireless sensor networks, ZigBee, sensor node, gateway node.
