Method and apparatus for resource reservation in a multihop wireless network
First Claim
1. A method for communicating a multihop flow reservation between a reservation originator and a reservation terminator along a path comprising a plurality of nodes in a multihop wireless network, the method comprising:
- communicating one or more reservation messages between each of the plurality of nodes and an associated next hop node, wherein each of the communicated reservation messages includes an information element comprising;
an identification of the reservation originator of the multihop flow reservation,an identification of the reservation terminator of the multihop flow reservation, anda sequence control, wherein the sequence control identifies a current state of progress of the multihop flow reservation within the multihop wireless network and wherein the sequence control is incremented to indicate an operation on the multihop flow reservation;
receiving one or more reservation messages at the associated next hop node;
determining, by the associated next hop node, if the identification of the reservation originator combined with a traffic stream identification/access category maps to a particular flow in a traffic stream table of the associated next hop node; and
creating a new entry in a traffic stream table for the identification of the reservation originator and the traffic stream identification/access category when the identification of the reservation originator combined with the traffic stream identification/access category does not map to a particular flow in the traffic stream table.

Abstract
A message format for use in one or more multihop flow reservation messages in a multihop wireless network includes a reservation originator identification; a reservation terminator identification; a sequence control; and optionally a flow originator identification. A multihop flow reservation comprises forwarding a traffic stream request including the message format and forwarding a traffic stream reply including the message format along a multihop route. After the traffic stream reservation is completed, a data is forwarded along the multihop route.
