Many applications of sensor network require connection to the Internet. The transmission protocol of traditional sensor network was designed within the sensor network itself. However, based on 6LoWPAN which can be accessed using IPv6, direct connection is possible between the sensor network and the TCP/IP network outside. Transmission of data in ap plications of sensor network falls into two main categories. One is a small packet that is periodically produced such as pa cket related to temperature and humidity. The other is a relatively large packet that brings about network overheads such as images. We investigated the conformance test and pros and cons of application data over the transmission protocol of Z igbee and 6LoWPAN. As a result, both Zigbee and 6LoWPAN have shown low rate of loss for periodic data and have in creased reliability of data transfer. When transmitting streaming image data, both ACK, non ACK mode of Zigbee and UD P of 6LoWPAN minimized transmission time but suffered the consequences of high packet loss. Even though TCP of 6Lo WPAN required a long transmission time, we were able to confirm that no loss has occurred.
