Patent number: 8942188Abstract: The present invention relates to a method of reducing beacon collision probability in a communication network supporting control channels comprising beacon periods divided into beacon slots, each beacon period being followed by a contention period. In the method a communication device (101) operating in the communication network first chooses (503) an available beacon slot for transmission of a first type of beacon for exchanging network topology information with other communication devices operating in the communication network. Then the communication device transmits (515) a beacon of a second type comprising an identifier of the communication device and the chosen beacon slot for the transmission of the beacon of the first type, the beacon of the second type being transmitted in the contention period.Type: GrantFiled: August 22, 2008Date of Patent: January 27, 2015Assignee: Koninklijke Philips N.V.Inventors: Hans-Juergen Reumerman, Yunpeng Zang, Lothar Stibor, Bernhard Walke, Hong Ma

Patent number: 8625546Abstract: This invention defines a medium access protocol for the support of mesh networking in wireless communications. It defines a phase for intra-cell and a phase for inter-cell traffic. During the inter-cell traffic a beacon phase is used for the reservation of transmissions. In this phase also information about the mesh topology is included and parallel transmission are supported. Even though this medium access protocol is intended to be proposed in standardization of IEEE 802.11 mesh networks (802.11) it could be used in any wireless mesh network.Type: GrantFiled: January 9, 2012Date of Patent: January 7, 2014Assignee: Koninklijke Philips N.V.Inventors: Hans-Juergen Reumerman, Guido Roland Hiertz, Gustaf Sebastian Max, Yunpeng Zang

Patent number: 8570868Abstract: A congestion control method for a communication system supporting layered radio channel structure for communication between at least a first communication device and a second communication device that offers a first and second types of service with corresponding first and second priority orders. The messages between devices include a preamble and a payload with each message being separated by at least a minimum allowable period. The first communication device generates a physical layer message pertaining to the first type of service, senses the radio channel idle for at least a period corresponding to the minimum allowable period between two messages, and transmits the physical layer message including a preamble indicative of the type of service the message pertains. The content of the preamble is detected by the second communication device within a communication range irrespective of the decoding state of the payload of the transmitted message.Type: GrantFiled: December 9, 2008Date of Patent: October 29, 2013Assignee: Koninklijke Philips N.V.Inventors: Hans-Juergen Reumerman, Guido Roland Hiertz, Yunpeng Zang, Gustaf Sebastian Max, Lothar Stibor, Bernhard Walke

Patent number: 8532060Abstract: In a wireless mesh network, an algorithm is used by mesh points in the network to predict the success of and interference created by a new transmission opportunity. In particular, it is provided a method for mesh points, in a mesh network, to determine whether to transmit to another mesh point simultaneously while another transmission is taking place on the same communication link. A mesh point should not transmit to another mesh point if the mesh point's transmission interference disturbs a simultaneous transmission from another mesh point. Furthermore, a transmitting mesh point should not transmit to a receiving mesh point if the transmission will be disturbed at the receiving mesh point from interference from a simultaneous transmission from another mesh point.Type: GrantFiled: May 12, 2006Date of Patent: September 10, 2013Assignee: Koninklijke Philips N.V.Inventors: Hans-Juergen Reumerman, Francesc Dalmases, Guido Roland Hiertz, Gustaf Sebastian Max
