MAXIMUM THROUGHPUT OF 10 NODES FOR IEEE 802.15.4 WPAN (WIRELESS PERSONAL AREA NETWORKS)

ZigBee is the result of ZigBee Alliance and is also an open global standard providing wireless networking based on the IEEE 802.15.4 standard. IEEE 802.15.4 consists mainly of Physical and MAC layers.ZigBee and the underlying protocol IEEE 802.15.4 were developed with low data rate. Data rate requirements for audio will range between tens of Kbps and hundreds of Kbps. Compression methods could be applied to reduce the data rate. We can use IEEE 802.15.4 for this reduced data rate. This paper describes a five-phased approach for measuring and attaining the maximal throughput for 10 nodes in IEEE 802.15.4. The phases consist of: 1) theoretical calculations for single-hop 2) theoretical calculations for multi-hop 3) NS-2 simulations for single-hop 4) NS-2 simulations for multi-hop 5) NS-2 simulations for 10 nodes.
