Method and device for establishing communication links and for estimating overall quality of a directional link and reporting to OLSR in a communication system
First Claim
1. A wireless communication network comprising:
- a plurality of mobile nodes each comprising a transceiver, a directional antenna connected to said transceiver, and a controller connected to said transceiver and comprising a communications router to discover routes and route communications to neighboring nodes with a routing protocol, a time slot scheduling unit to schedule time slots to establish a communication link with each neighboring mobile node, an antenna aiming unit to aim said directional antenna toward each neighboring mobile node during communication therewith, and a link quality estimator to estimate link quality based upon the quality of each time slot scheduled for the communication link and to report estimated link quality to the communications router.

Abstract
A wireless communication network includes a plurality of mobile nodes each including a transceiver, a phased array antenna connected to the transceiver, and a controller connected to the transceiver. The controller discovers routes and routes communications to neighboring nodes with a routing protocol, e.g. an Optimized Link State Routing (OLSR) protocol. The controller schedules time slots to establish a communication link with each neighboring mobile node, and the phased array antenna is aimed by the controller towards each neighboring mobile node during communication therewith. Also, the controller estimates link quality based upon the quality of each time slot scheduled for the communication link and reports estimated link quality to the routing protocol.
