Method for determining transmission channels for a LPG based vehicle communication network
First Claim
1. A method for determining a transmission channel for multi-hop transmission of a data packet from a plurality of data channels in ad-hoc network, the ad-hoc network comprising at least one local peer group, the local peer group having a plurality of moving vehicle as network nodes, the method comprising the steps of:
- determining available channels for next-hop neighbor routing for data packet transmission at a node by scanning MAC layer channels;
transmitting a first list of available non-conflicting wireless channels or frequencies based on channel usage to at least one other node wherein said transmitting step includes adding the first list of available channels to a membership report message or a heartbeat control message;
receiving, from the at least one other node, a second list of available channels for the at least one other node;
creating by a group header an available channel table including the first and second lists of available channels;
selecting by each node or by a group header a transmitting channel for a data packet based upon information in the available channel table wherein the first list, second list, and the selected channel is transmitted on a dedicated control channel; and
advertising by each node the selected channel to the at least one other node.

Abstract
A method for determining a transmission channel for multi-hop transmission of a data packet from a plurality of data channels in an ad-hoc network. The network includes at least one local peer group. Each local peer group has a plurality of moving vehicles as nodes. The method comprises steps of determining available channels for data packet transmission at each node, transmitting a first list of available channels to at least one other node, receiving, from the at least one other node, a second list of available channel for the at least one other node, creating an available channel table including the first and second lists of available channels, selecting a transmitting channel for a data packet based upon information in the available channel table, and advertising the selected channel to the at least one other node.
