Survey Paper on Bluetooth and Its Applications

Bluetooth is an open specification for short-range wireless communication and networking, mainly intended to be a cable replacement between portable and/or fixed electronic devices. The main aim of introducing Bluetooth is to connect two or more devices without any physical connection. This helps to reduce time and human efforts for transferring data. The specification also defines techniques for interconnecting large number of nodes in scatter nets, thus enabling the establishment of a Mobile Ad hoc network (MANET). While several solutions and commercial products have been introduced for one-hop Bluetooth communication, the problem of scatter net formation has not yet been dealt with. This problem concerns the assignment of the roles of master and slave to each node so that the resulting MANET is connected. The range of Bluetooth is up to 60metres.So we are basically focusing on the idea to improve in some essential areas. In this paper we have included some important features like scatter net and piconet, Bluetooth Protocol Stack. We have also dealt with different versions of Bluetooth according to their date of release. Also we have discussed the fundamentals of communication and connection and pairing and bonding mechanisms. Our future scope area mainly focuses on power and energy saving in the future Bluetooth devices or any such equipment’s. In today’s era we are having gadgets using different operating systems. The pairing between the devices is not up to the mark so also aim at presenting the idea of gathering opportunities to improve upon the compatibility feature.
