Title: SYSTEM, METHOD AND APPARATUS FOR RELIABLE EXCHANGE OF INFORMATION BETWEEN NODES OF A MULTI-HOP WIRELESS COMMUNICATION NETWORK
Abstract:
Techniques are provided for reliably distributing network management information in an ad hoc multi-hop wireless network which includes a number of existing nodes. A first node selects a particular timeslot in a dedicated channel based on the network management information received from the neighbor nodes and determines, via a contention channel, if the particular timeslot is being used by any neighbor nodes of the first node. If the particular timeslot is determined to be unused, then it is assigned to the first node for periodically transmitting network management information.
