2005 (English)Patent (Other (popular science, discussion, etc.))
NOVELTY - The method involves determining a parameter common to all links along an entire multihop route based on a given end-to-end (ETE) transmit parameter constraint. A set of three interdependent link transmit parameters is assigned for each number of links, where each parameter is dependent on local link characteristics such as a link transmit parameter representative of link transmit energy, link transmit time, link transmit bandwidth and link code word consumption, and a link transmit parameter representative of link transmit power, based on a common parameter and the local link characteristics. USE - Used for controlling link parameters for a multihop route in a multihop network (claimed). ADVANTAGE - The determination of common parameter to all links along the entire multihop route based on the given end-to-end (ETE) transmit parameter constraint more flexibly and efficiently assigns/allocates link transmit parameters in a multihop network, thus providing improved method for controlling link transmit parameters for a route in the multihop network. The method more optimally utilizes the available network resources for transmitting information over the links, while ensuring a certain quality for the route and minimizes the use of expensive resources such as transmit energy/power. The improved method performs efficient multihop routing, joint routing and end-to-end (ETE) considerate link control, enables improved link adaptation and power control strategy and allows reduced interference, specific absorption rates (SAR) and increased battery lifetime. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method of routing in a multihop network (2) an arrangement for controlling link parameters for a multihop route (3) an arrangement for routing in a multihop network (4) an apparatus for controlling link parameters for a multihop route, comprising a resource controller. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic flow representation of a method for controlling link transmit parameters for a multihop route.
