Context-free protocol for enforcing data forwarding in wireless ad hoc networks
Described herein is a context-free protocol (i.e., the COFFEE protocol) for stimulating cooperation among selfish nodes. Various embodiments have the ability to transmit a packet over the path successfully without the dependency on the information of other packets' transmissions. It is assumed that every node in the network is rational, and therefore during the packet forwarding stage, if the intermediate nodes can not clearly tell whether the packet is destined to them or not, they do not simply drop the packet. Thus, in the COFFEE protocol, by introducing several techniques, for a packet received by a node, the node thinks the packet could potentially be destined to itself and forwards the packet to find out the answer. Detailed analysis and performance evaluations have been conducted to demonstrate the effectiveness of the COFFEE protocol.
