Bluetooth is a short distance and low-power wireless transmission technology. Although the application of Bluetooth technology, models, mainly in a piconet (Piconet) within the means of communication, but I believe in the near future after the more popular Bluetooth chips, decentralized network (Scatternet) the application of model will continue to emerge. For example, in a meeting among the many people involved with each other via Bluetooth scatter-net formation, mutual transmission of documents and files. However, to achieve Scatternet related applications is obviously necessary to first solve the network data transmission problems between devices that are to provide multi-point to generation packet forwarding mechanism, known as routing protocol (Routing protocol). NS2 software used in this paper to simulate in a Bluetooth piconet, the Bluetooth packet transmission by analysis of transmission over the packet transmission path, packet transmission delays or lost, to find solutions related to the corresponding methods to increase the efficiency of data transfer, so that Bluetooth network to improve the stability of the overall transmission.
