The objective of our project is to build a simulation model of LR-WPAN and simulated the model using the Network simulator NS2. The WPAN Low Rate Task Group (TG4) is chartered to investigate a low data rate solution with multi-month to multi-year battery life and very low complexity. This standard specifies two physical layers: an 868 MHz/915 MHz direct sequence spread spectrum PHY and a 2.4 GHz direct sequence spread spectrum PHY. The 2.4 GHz PHY supports an over air data rate of 250 kb/s and the 868 MHz/915 MHz PHY supports over the air data rates of 20 kb/s and 40 kb/s. We simulated models for 2.4 GHz band. The low rate WPAN supports two types of topologies. They can form a star topology where the nodes can only talk to the coordinator and also as in a peer-to-peer topology where capable network nodes can route data. Several peer-to-peer topologies
Network can work together to form a mesh/cluster tree topologies. Two models of different topology namely Star and Peer-to-peer topology is created and then simulated. The code for the simulations is written using C++ and Tool command language. The simulation for both the models runs for up to 100 seconds.
The Simulated model can be analyzed as an animation for the process using the tool network animator. The main advantage of simulating using NS2 is that overall performance of each packet can be studied. The trace files are generated which shows the complete performance of the model simulated.
