IEEE 802.15.4(Zigbee)[1] standard is low data rate,low power consumption and low cost wireless personal area network.In order to transmit large amount of information that require high data such as video, image and audio and its encryption and decryption is considered.Zigbee in general uses a single channel for data transmission.In this paper we proposeddata transmission (pdf,image) over zigbee networks with DES encryption,which aims to improve total throughput of networks and secure transmission of data
