Bluetooth technology is intended primarily as a replacement of cables between electronic devices, as in Personal Area Networks (PANs), or for connecting the components of a computer system. In addition, larger topologies like “scatternets” are targeting wider geographical area applications in colleges, universities, factories, warehouses, shopping malls and various sensor network applications. For scatternet formation and scheduling issues, less attention has been given to optimizing scatternet topologies. Sizing a scatternet in terms of minimizing the number of piconets has been addressed.

The short range communication technologies like scatternet formation has not been formally defined in the Bluetooth SIG specifications. As a result, numerous protocols have been proposed. While modeling ad-hoc networking, in general, is complex, the additional restrictions imposed by the Bluetooth specifications—such as low cost of the device, low power consumption and network resilience while using piconets that have a maximum of seven active nodes—have created a significant challenges.

This paper addresses the challenges of scatternet formation for multi-hop to Bluetooth based personal area and adhoc networks, with minimal communication overhead. In a multi-hop adhoc network, all wireless devices are in the radio vicinity of each other, e.g., electronic devices in a laboratory, or laptops in a conference room.

In this paper we apply a method to multi hop networks, by showing that position information is then not needed. Each node can simply select a virtual position, and communicate it to all neighbors in the neighbor discovery phase. In this paper, architectural challenges during design of short range communication technologies are considered.
