We investigate a price-based reliable routing game in a wireless network of selfish users. Each node is characterized by a probability of reliably forwarding a packet, and each link is characterized by a cost of transmission. The objective is to form a stable and reliable routing path between a given source and destination pair. The pricing mechanism involved in this routing game is destination-driven and source-mediated: for each successfully delivered packet, the destination node pays the source, which in turn compensates all nodes that participate in routing the packet. We develop a polynomial-time algorithm for deriving an efficient Nash equilibrium routing path. We also present simulations to evaluate the reliability of the obtained path with respect to prices and source-destination cooperation for different network settings.
In REF , Liu and Krishnamachari presented a polynomial-time algorithm to find a Nash equilibrium path.
