Abstract:
1. A method of reserving wireless communication bandwidth in an ad hoc network in which nodes are capable of routing data by forwarding data to other nodes in the network, the method comprising: transmitting, by a first node to a plurality of receiving nodes, first scheduling data sufficient for a receiving node in the plurality of receiving nodes to predict times at which the first node will be available to receive wireless communications from the plurality of receiving nodes (“receiving times”); and transmitting, by the first node to the plurality of receiving nodes, second scheduling data including an identified set of nodes, wherein the second scheduling data is sufficient for the receiving node to predict times reserved for communications from the identified set of nodes to the first node (“reserved times”), during which times: thereby reserving times for nodes in the identified set of nodes to communicate with the first node, wherein the first node, the receiving node, and the nodes in the set of nodes share a common algorithm for predicting the receiving times and the reserved times based on the first and second scheduling data; powering up a receiver of the first node during the receiving times, such that the first node can receive communications from one of the receiving nodes; and fully powering down a receiver of the first node during times other than the receiving times, such that the first node does not receive communications via the receiver.
