The Application Of CDMA Module In Wireless Sensor Networks

As a new kind of Ad hoc network, wireless sensor network (WSN) has the advantages over the typical wireless networks, such as providing coverage of a large area, easy to deploy, improved anti-destructibility. Medical treatment, detecting environment hazards and military surveillance are among many WSN applications. In this paper, the sink node of WSN that is designed on the base of CDMA module is presented. The sink node act as a connector in WSN, it transmit the acquired data to the remote monitoring center with the help of CDMA module, which is droved through serial interface, after processing the data collected by sensor nodes. Due to the features of the CDMA network technology, this type of WSN whose sink node is based on CDMA module is extremely fit for the applications which need high anti-interference and transmission rate..
