A performance analysis of multimedia traffic over zigbee network
MetadataShow full item record
A Wireless Sensor Network (WSN) offers the advantages of low power consumption and low cost. For some applications e.g. distributed surveillance, emergency, and rescue etc., ZigBee technology is needed to support multimedia traffic e.g. image, video streaming. However, transferring multimedia traffic over a ZigBee network is a challenging task because of its low data rate i.e. 250 kbps at 2.4 GHz. This paper investigates the performance of image and video transmission for three topologies e.g. Mesh, Star and Tree topologies over Zigbee network using Riverbed Modeler Academic Edition (MAE). The result shows that Mesh topology outperforms over Star and Tree topologies in terms of traffic reception for both image and video transmission.
