This paper aims to implement multiple sharing of data as well as broadcasting message by providing full duplex connectivity via Bluetooth using the Juggler concept of multi-hop conventions already being implemented in wired connectivity. At present, it is impossible to provide a full duplex connection in Bluetooth based devices. To overcome this problem, we have come up with a concept that efficiently utilizes the Juggler. Furthermore, it also aims to improve the security factors for the network by implementing RC4 and MDS cryptography techniques. The MDS (Maximum Distance Separable) is used for increasing the diffusion property. Conjurer is similar to a juggler who juggles objects while performing magic. Likewise, Juggler provides nearly instantaneous handoff between base stations or supports a modest sideband channel with peer nodes, without adversely affecting foreground throughput. The Juggler switches frequency between different base stations using the frequency transition table for optimizing the overall usage of the bandwidth between these stations, thereby preventing any form of wastage of data and bandwidth. Furthermore, we ensure that both the sender and the clients issue concurrent network flows so that Juggler is able to assign these flows across more than one access point, providing significant speedup when wired-side bandwidth from the access point constrains end-to-end performance. Moreover, the concurrent connectivity prevents any bluetooth attack between the clients as the sender keeps track of the activities of each of his/her client.
