Abstract
Official abstract text for this publication.
Message are broadcast in a vehicular environment using a network of nodes, wherein each node includes a transceiver and a processor arranged in a vehicle, and a bandwidth of the network is partitioned into a control channel (CCH) and multiple service channel (SCH). Time is partitioned into alternating control channel intervals (CCHI) and service channel intervals (SCHI). A source node detects an event and broadcasts a message related to the event. The message specifies current channels and next channels used by the source node to broadcast the message. The message is received in a set of relay nodes. Then, each relay node that receives the message rebroadcasts the message during the SCHI on the CCH or any other channels not specified in the message.
First claim
Opening claim text (preview).
We claim: 1. A method for broadcasting a message related to a vehicular environment using a network of nodes, wherein each node includes a transceiver and a processor arranged in a vehicle, wherein a bandwidth of the network is partitioned into multiple channels including a control channel (CCH) and six service channels (SCH), wherein time is partitioned into alternating control channel intervals (CCHI) and service channel intervals (SCHI), and wherein all nodes monitor the CCH cha…
