nected piconets within the scatternet form a backbone for the Mobile Area Network (MANET), and can enable devices which are not directly commu- nicating with each other, or which are out of range of another device, to exchange data through several hops in the scatternet. Current implementations of Bluetooth depend primarily on simple point-to-point data links between Bluetooth devices within Figure 1: An example of a Bluetooth scatternet In the Bluetooth specifications [5], the capacity allocation by the master to each link in its piconet is left open.

Scatternet is formed two or more piconets form a network, it actually acts as a bridge between multiple piconets. Both are usually applied to Bluetooth devices. Moreover scatternet and piconet are ad hoc computer networks. Piconet has a maximum network range of 7 devices while scatternet has a range of more than 8 devices. Both are applied to wireless Bluetooth technology/devices. The devices Overlaid Bluetooth Piconets (OBP) does not require Scatternet connection. So, all Bluetooth devices used in the world can use OBP as a Piconet inter- connection method and form a virtual Scatternet, even if they do not support

Scatternets can be formed when a member of one piconet (either the master or one of the slaves) elects to participate as a slave in a second, separate piconet.

Bluetooth devices communicate with each other in a master/slave configuration. This means that devices do not communicate as equal peers on a collision prone medium, as in 802.11 .

5.8.2 Topology . There are two types of topology for Bluetooth – Piconet, Scatternet. The Piconet is a small ad hoc network of devices (normally 8 stations) as shown in Fig. 5.8.1. The fig shows a scatternet consisting two piconets. A slave in the first piconet can act as a master in the second piconet. It will receive the messages from the master in the first piconet by acting as a slave and then delivers the message to the slaves in the second piconet as shown in the figure.

23/10/2016В В· A scatternet is a number of interconnected piconets that supports communication between more than 8 devices. Scatternets can be formed when a member of one piconet (either the master or one of the slaves) elects to participate as a slave in a second, separate piconet. Scatternets are formed by allowing certain piconet members to participate in several piconets by periodically switching between them. Due to the fact that there is no scatternet formation procedure in the Bluetooth

number of devices in a piconet. Bluetooth may be extended to interconnectmultiple piconets to form a scatternet. In figure 1, Bluetooth scatternet construction. In Section 3, we describe the Bluetooth network model. We introduce our evolutionary approach to scatternet construction in Section 4. Our simulation results are presented in Section 5. Section 6 concludes the paper. References are Although protocols for intra-piconet scheduling have been studied extensively [6, 19, 20, 24, 36], the bluetooth specification does not prescribe any particular approach to scatternet-wide link scheduling. A number of proposals have been made regarding scatternet scheduling, many of which are based on the concept of rendezvous points.

piconet and scatternet bluetooth pdf

PDF Bluetooth enables wireless communication via ad-hoc networks. The basic topology (piconet) is a collection of slaves controlled by a master. A scatternet is a multihop network of piconets. A scatternet is basically two piconets in proximity to each other where one node is simultaneously in two piconets. That node may be a slave in each piconet or a slave in one and a Master in the other piconet. A scatternet can be used to extend the range (i.e. mesh) of Bluetooth or enable complex topologies for desired use cases. An early example of the latter was if you had two laptops with
