Publication number: 20090172117Abstract: Methods support a sleep mode for an embedded device. Embedded devices like sensors and actuators used in wireless sensor networks have a limited power supply. To conserve energy and thus increase the lifetime of these devices, the devices should be put into a stand-by mode (also called sleep-mode) when they are not used. These methods support the sleep mode at a higher level than the MAC layer, thus avoiding the problems of prior art approaches. Methods are exemplarily described for the case of the message queuing telemetry transport protocol for sensor networks. They can easily be adapted to other protocols.Type: ApplicationFiled: January 2, 2008Publication date: July 2, 2009Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Bharat V. Bedi, David C. Conway-Jones, Urs Hunkeler, Thomas J.W. Long, Andrew J. Stanford-Clark, Hong Linh Truong, Nicholas C. Wilson

Patent number: 7512097Abstract: Provides apparatus, systems and methods for adapting a first and second transmission parameter R, P in a transmitting node of a data communication system to the current link quality of a data communication channel. A method comprises in the transmitting node counting the number of successful transmissions s, each successful transmission bases on a receipt of an acknowledgment “ACK”, and comparing the number of successful transmissions s against a threshold value Smax. In the event of reaching the threshold value Smax and operating with the first and second transmission parameter R, P in a predetermined parameter space, the method further comprises adapting at least one of the first and second transmission parameters R, P in dependence on a critical value that due to the current link quality corresponds to a temporarily unsupported value of one of the first and second transmission parameters R, P.Type: GrantFiled: December 1, 2004Date of Patent: March 31, 2009Assignee: International Business Machines CorporationInventors: Jens Jelitto, Hong Linh Truong
