Bluetooth has gained popularity from last few years due to its simple and economical Bonding features. Bluetooth was established to bond few devices together within some predefined range. But today's technologies required Bonding of larger networks using shortest path, less time consumption and minimum possible utilization of resources. The inherited nature of Bluetooth technology is to search and make Bonding with other devices within allowable range having time consuming long query/query scan and pager/page scan process, this process result in a scatternet formation and inefficient Bonding. Usually in this scatternet formation each and every slave is bonded with every available slave whether Bonding is required or not. This simple means the wastage of resources. Another very inefficient operation in scatternet formation is, suppose if we have two piconets A and B, forming a scttternet, piconet A having 7 slaves and 1 master, similarly piconet B also have 7 slaves and 1 master, if salve number 6 of piconet A wants to communicate with slave number 4 of piconet B for this Bonding formation the inherited process of Bluetooth is Slave 6 of piconet A go to its master and generates a request that it wants to communicate with slave 4 of piconet B, Master of piconet A goes to Master of piconet B with this request, afterwards Master of piconet B checks whether its salve 4 is free or not at the moment, if slave 4 is free Master sends back acknowledgment to Master A to allow Bonding between both slaves and Master A calls its slave 6 to communicate. After this long, time consuming and resources consuming process Bonding is started if and only if the link is still established but if link has disconnected than again for Bonding of slave 6 and slave 4 this inefficient process is revised ....having look at this Bonding scenario practically for only two slaves Bonding 6 routing paths/resources are required which is very inefficient approach of Bluetooth Bonding due to which Bluetooth is unable to transfer/receive heavy data with reliability, research on Bonding shown that in wireless Bonding routing has to be very efficient having shortest distance between two nodes ability to handle larger data. in this paper we present an algorithm which successfully Address the above discussed problems. This proposed work concludes and will prove that slaves should be communicating directly to each other and they must be bidirectional as well. This work is basically an extension chain of our previously published research on various dimensions of Bluetooth technology. [1, 2, 3].
