A method of and fuel cell system for limiting an amount of a fuel crossing over a membrane in a fuel cell, the method including determining an appropriate molecular ratio of the fuel and water for a fuel-water mixture; and controlling an amount of the fuel-water mixture that is available to an anode side of the membranein the fuel cell according to an amount of the fuel that will be electro-oxidized by the fuel cell. The fuel cell system includes a fuel cell membranehaving an anode layer, a cathode layer, and an electrolyte layerwhere the cathode layer is exposed to an oxygen source, and a fuel delivery systemincluding a fuel chamberdisposed around and proximate to the anode layer at a side opposite to the electrolyte layer, the fuel delivery system implementing the method above.

A node () includes a processor () for determining neighbor nodes in a routing path to a destination based on a routing table associated with the node (). The node () includes a memory for storing a first authenticated tokens. The node includes a transmitter () for transmitting a first request-to-route (RTR) message including an indication specifying information units (IUs) from the first node to the neighbor nodes in a routing path from the first node to the destination. The node () includes a receiver () for receiving a neighbor reply message from one of the neighbor nodes to the first node which indicates that the neighbor node will route the information units (IUs). The transmitter () transmits a second authenticated tokens from the first node to one of the neighbor nodes. The second authenticated tokens are converted into a tradable entity and provide compensation to the neighbor node selected.

Method and apparatus for encouraging routing in a network

Techniques are provided for allowing a node () in an ad hoc network to deterministically decide whether to relay broadcast information to another node in the ad hoc network. The node () receives broadcast information and measures received signal strength (RSS) of the broadcast information. The node () may determine if the measured RSS is below a low threshold, and if so, can relay the broadcast information to neighbor nodes. Otherwise, the node () can also determine if the measured RSS is above a high threshold, and if not, wait for a waiting period before relaying the broadcast information to the neighbor nodes. The node () may dynamically adjust the low threshold by decreasing the low threshold as the number of neighbor nodes increases and may dynamically adjust the high threshold by increasing the high threshold as the number of neighbor nodes decreases.

A communication system and a method of communicating data. A first backhaul site can be dynamically selected from a plurality of backhaul sites that are each configured to wirelessly communicate with an access point. A controller can dynamically configure a transmission parameter used to communicate a first backhaul data stream between the access point and the first backhaul site. The first backhaul data stream can be derived from a source data stream and can be wirelessly communicated between the access point and the first backhaul site. A second backhaul site also can be selected. A second backhaul data stream also can be derived from the source data stream and wirelessly communicated between the access point and the second backhaul site. The first and second backhaul data streams can be combined.
