Abstract
A wireless mesh network architecture includes a plurality of wireless nodes, with each wireless node in the network is connected to every other wireless node in the network. Each pair of wireless nodes is coupled by a link dedicated to exchange of data by the pair of nodes. The link is characterized by an agreement between two end points of the link to rendezvous for the purposes of exchanging data at a predetermined time over a predetermined channel. Methods of negotiating rendezvous characteristics, such as rendezvous channel, time, frequency, duration and transmission power ensure that the selected link is tuned to minimize interference and power usage in the WN. A handshake mechanism enables high performance data delivery with minimal packet loss. The link based architecture uses Link State Advertisements, traffic tags and spanning trees to fine tune packet flow through divergent devices in the network.
