Abstract

A method for connecting two or more devices via a wireless communication channel is provided. In one embodiment, a method of connecting a first device to a second deviceincludes the steps of arbitrarily assigning one of twopossible states to each device, wherein in a first state, a device seeks to establish a connection with another device, and in a second state, the device renders itself available for connection with the other device; and alternating a present state of each device between the first state and the second state in accordance with a predefined probability distribution until either a predetermined timeout period has expired or a connection between the devices has been established, the length of time that each device remains in the first and second states being controlled by the probabilitydistribution. In a second embodiment, a method of forming a scatternet between a plurality of devices or nodes in an ad hoc wireless communication network is provided.

Description

technical field

[0001] The present invention relates to communication networks, and more particularly to methods of connecting two or more devices in an ad hoc wireless communication network. Background technique

[0002] Bluetooth is a new technology developed as a short-range (about 10 meters) wireless cable replacement for linking portable consumer electronics such as cell phones, headsets, PDAs, and laptops, but it is also suitable for Fax machines, printers, toys, digital cameras, home appliances, and virtually any other digital consumer product or application. The technology essentially provides a mechanism for forming a small wireless network between Bluetooth-equipped devices based on ad hoc organization. It can also be used as a wireless communication bridge to existing data networks. Current Bluetooth implementation efforts generally focus on point-to-point client-server applications, such as dial-up networking profiles, headset profiles, and local area network (...
