Abstract:
A method for controlling data transmission rate in a wireless network, the method comprising the steps of providing information of the interference margin (30) to a base station (12) by each active link, receiving a bandwidth allocation request (19) at one node, measuring a channel quality (20) for the node, and determining (21) a need to assign a power level and rate based on the information of the channel quality (20) of the node and the interference margin obtained (30) from the base station (12).
Abstract:
The present invention provides a controller that clusters the receivers and then reduces the forwarding states per cluster so as to offer a better performance of multicast routers by reducing the amount of total traffic injected into the network by each multicast session. The controller system enables the router to support a large number of receivers without compromising the memory size.
Abstract:
A system for communication in a wireless backhaul environment having wireless mesh networks connected in part to the Internet comprising a communication topology. The communication topology comprises communication cells each having a relay station and mobile nodes communicating to each other using 802.16j wireless technology wherein the cells are arranged in a grid fabric within the communication topology.
Abstract:
There is provided a method that allows adding complex dependency logic to an existing database for self organized system without having to modify the underlying structure of the database. The present invention provides a way to flexibly handle record state transitions by using an event model. In other embodiment of the present invention an event meta-model is instantiated to represent a number of different event models and the corresponding dependencies that inter-relate them. Hash algorithm approach may be implemented for building the self-organized communication system database.
Abstract:
The present invention relates to a fast packet forwarding engine for scalable routing characterized in that wherein the present invention is a forwarding engine for multicast routers that accelerates the forwarding of packets such that it improves their performance to support group communications applications and wherein the present invention comprises of a bitmap field added to the packet header such as IP source address, the IP destination address and the bitmap field and wherein when a source wants to send a packet to an active receivers, it sends a packet to a router with bitmap configuration and with a receiver list and wherein the router performs route lookups for all destinations.
