Business Model for Distributed Infrastructure and Packet Delivery

By Doug Reed and Jack Smith

Distributed infrastructures such as those corresponding to Mobile or Fixed Ad-hoc Networks allow information packets to be transported between the subscriber and the base station through a series of multiple hops, if necessary. During each intermediate hop, a subscriber node or repeater node other than the destination node will receive the packet and then forward it to the next appropriate node on the route between its original source and its eventual destination. This practice of exchanging information packets between subscriber nodes is sometimes called a peer-to-peer communication process. Routing maps must be generated to determine how to form a path from the source to the destination. If subscribers move around, the routing map must be updated to adapt to the changes in user position.

In such a system, it is desirable to balance the goals of having the fewest number of hops, which impacts delay, with that of having the best signal conditions, and therefore the lowest power transmission with the highest data rate possible. Such a system also requires some minimum number of peers with whom a connection can be made. To be able to make a connection to a peer and obtain a relay function for a packet, a sufficient number of peers must keep their radios on and incur the battery drain associated with relaying packets for others. This is a sacrificial act of service to others, particularly if the subscriber is a below-average user who supplies more resources (packet relays) than he requires. One way to limit the negative effect of relaying packets for others is to preclude this activity if one's battery is below a given threshold of remaining capacity.

This invention presents a business model that encourages users to participate in a distributed infrastructure and relay packets for others. The idea is to assign a value in advance for the packet relay service that others will provide. Thus, when the subscriber device is on and available to participate in packet relaying, a credit may be registered for this user. Additional credits are registered for the subscriber when he successfully relays packets. Thus by participating in supplying services to others, credits are accumulated. These credits may be recorded and accounted for by the service provider, by the individual subscriber for later download, or by third parties. Information may also be attached to the packets as part of their routing and this information used to measure credits for those who have participated in routing. In the preferred method, each subscriber who participates in relaying packets will record statistics on the number of packets processed, and the identification of the units from which he received packets, and those who he sent packets. This data will be transferred to the system controller at a convenient time. The system ...
