Resource reservation in a wireless network with distributed medium access control
First Claim
1. A method of virtual channel reservation in a wireless network with distributed medium access control, including:
- transmitting, from a source node, a virtual channel request over a transmission path including at least one intermediate node to a destination node, the virtual channel request requesting an allocation of transmission resources for the virtual channel from the source node through the at least one intermediate node to the destination node;
receiving, in the source node, a virtual channel confirmation from the destination node, the virtual channel confirmation indicating an allocation of the resources for the virtual channel request; and
transmitting data from the source node to the destination node using the allocated transmission resources,wherein the source node or an intermediate nod, in the at least one intermediate nod, to signaling between other nodes of the wireless network to determine unreserved transmission resources in the wireless network and wherein the virtual channel request requests establishment of the virtual channel using the determined unreserved transmission resources.

Abstract
A wireless network with distributed medium access control allows establishing of a virtual channel between a source node and a destination node via at least one intermediate node. The virtual channel may be established for the entire duration of a communication between the source node and the destination node, and, to establish the virtual channel, a request handler can transmit a virtual channel request, requesting an allocation of transmission resources for the virtual channel. Based on the virtual channel request, a virtual channel confirmation can be generated by the destination node and can be returned to the source node, indicating an allocation of the resources for the virtual channel. A communication handler can then transmit data from the source node to the destination node using the available transmission resources.
