Designing and Performance Evaluation of Low Bit Rate Audio Streaming Over Wireless Personal Area Network

The IEEE 802.15.4 is a Personal Area Network well-known designed for programs like wireless monitoring and control of lights, protection alarms, movement sensors, thermostats and smoke detectors. IEEE 802.15.4 specifies bodily and media access manages layers that have been optimized to make certain low strength consumption. For the conversation among two nodes, best throughput for IEEE 802.15.4 is 250 kbps on a 2.4GHz band. However, because of header overhead, the done throughput is much less than 250 kbps. Also, the range of nodes taking element in a conversation has a substantial impact on throughput. The best bit rate for Zigbee/IEEE 802.15.4 is 250 kbps for the 2.4GHz band. The bit rate of 250 Kbit/s consistent with the channel and cannot be fully used for the payload (audio records). There is an overhead associated with the manner that the conversation works. Numerous mechanisms have to be taken into account while estimating the powerful transmission rate. ZigBee has a layer shape, and every layer adds additional header statistics, in order that the payload at the quit is less than the quantity of information this is sent. The overall amount of more bytes relies upon at the layer from which the utility runs, and on the operating mode of the verbal exchange machine. The principle goal is to calculate maximum throughput for audio streaming the usage of IEEE 802.15.4 for 10 different nodes. IEEE 802.15.4 defines specific layers but right here, we do not forget the Physical layer (PHY) and Medium Access manage (MAC) sublayer.
