Embodiment Construction

[0019] figure 1 is a network diagram illustrating the interaction of said devices according to an embodiment of the invention, comprising a mobile ad hoc communication network. In one embodiment, the mobile ad hoc communication network is a Bluetooth piconet comprising one master device and at most seven active slave devices. Such as figure 1 As shown, piconet 100 includes five instances of server 110 and terminal 120 . The network clock is maintained by the server 110 , which is the communications manager for each terminal instance 120 . Server 110 typically initiates a data exchange with terminal instance 120 . Two instances of Terminal 120 normally communicate through said server 110, but if two instances of Terminal 120 communicate directly, one instance will assume the role of server or master, while the other instance will assume the role of client or slave .

[0020] Each device in the mobile ad hoc communication network will assume the role of a terminal device ...

Abstract

A computer system, method, and computer program product for locating target devices that support a required service in an ad-hoc communications network. The ad-hoc communications network connects devices and support services. Each target device is one of the devices and the required service is one of the services. The method comprises conducting an inquiry of the ad-hoc communications network to discover nearby devices. If the inquiry indicates that the nearby devices may include a middleware layer, the method further comprises creating a connection to each of the nearby devices and confirming whether each of the nearby devices includes the middleware layer. For each of the nearby devices that includes the middleware layer, the method further comprises sending a service discovery request, and receiving a response that includes distributed information. The distributed information includes associations between the services such as the required service, and the devices such as the target devices.

Description

technical field [0001] The present invention generally relates to communication between devices connected to a wireless communication network. In particular, the present invention is a mechanism for improving the establishment and control of link connections between wireless communication devices within an autonomous transient (ad hoc) network. Background technique [0002] Short-range wireless systems have a range of less than a hundred meters, but can connect to the Internet, thereby providing communication over longer distances. Short-range wireless systems include, but are not limited to, wireless personal area networks (PANs) and wireless local area networks (PLANs). Wireless PANs use low-cost, low-power wireless devices that typically have a range of 10 meters. An example of a wireless PAN technology is the Bluetooth standard. The Bluetooth standard operates in the 2.4GHz Industrial Medical (ISM) frequency band and provides a peak air link speed of one Mbps, and low...
