Patent ID: 7742448

Claim:
In a multihop network comprising at least one first type of node and a plurality of nodes comprising at least one of a second type of node and a third type of node, a method comprising: transmitting a node identifier and status information from each of the nodes to the first type of node, wherein the status information associated with each node comprises: a node type comprising one of a second type of node and a third type of node, and a mobility state of the node comprising one of a fixed/stationary state or a mobile state; storing the node identifier and the status information from each of the nodes at the first type of node; allocating, at the first type of node, a channel resource to each of the second type of nodes having a mobile mobility state at a first time, wherein the channel resource is for exchanging topology information with the first type of node; and deallocating, at the first type of node, the previously allocated channel resource reserved for ones of the second type of nodes which have experienced a change from a mobile mobility state to a non-mobile mobility state during a period between the first time and a second time.
