1. A method for communicating among stations in a network comprising:
- at a determining station;
determining costs between the determining station and a headend for a plurality of paths through a respective plurality of stations;
selecting a low cost path between the determining station and the headend based on the determined costs; and
transmitting the determined cost of the selected low cost path.

Abstract
Methods, systems, and apparatuses are described for communicating among stations in a network. A station in the network can determine costs between that station and a headend through a number of other stations and selecting a low cost path from among the possible paths. Cost data from the determination can be transmitted from the station to other stations in the network for use in selecting low cost paths at those stations.

33. A method for communicating among stations in a network comprising:
-
receiving a route update request from a downstream station at a current station, the route update request including a list of station identifiers corresponding to stations that can be reached through the downstream station; updating a routing table by storing the list of stations identifiers in the routing table, the list of stations being stored with an association to a servicing station identifier, the servicing station identifier being an identifier of the downstream station, the association indicating that the stations can be reached via the downstream station; and transmitting a route update request to an upstream station. - View Dependent Claims (34, 35)

36. A method for communicating among stations in a network comprising:
monitoring periodic beacon messages from a first and a second upstream station at a monitoring station, the first upstream station being designated as a next upstream hop station for the current station, the beacon messages including first and second cost data for communicating with a headend through the first and second upstream station respectively. - View Dependent Claims (37, 38)

39. A network station configured to:
-
determine costs between the network station and a headend for a plurality of paths through a respective plurality of stations; select a low cost path between the network station and the headend based on the determined costs; and transmit the determined cost of the selected low cost path. - View Dependent Claims (40)
