My Project | Low Rate Wireless Personal Area Networks in NS2

LR-WPAN is a promising new wireless short range communications technology. It may not have yet swept the short range communications market but it is surely making its presence felt. An alliance of companies called the Zibgbee alliance, have already joined hands to benefit from this new technology and share information and develop new applications. With its promises of short range communications with very low datarates and ultra low power consumption, it has created a market for itself.
A detailed study of the zigbee technology with its internal architecture, and the layered structure has been conducted. Followed by it is a similar study of the simulator environment (ns-2). A detailed study of the zigbee modules built under ns-2 with reference to its implementation in the standard also has been done. Later a well behaved and near realistic simulation scenario is built in TCL. The zigbee modules have been exclusively tested for the simulator environment and several loopholes have been identified. These loopholes are further investigated to replace them with working modules. Both Star and Peer-to-peer topologies have been studied and finalized that the star topology can be used effectively for short range application whereas the peer-to-peer can be used for large application which involves many number of devices.
