...nistic overhearing, the connectivity between the mobile node and base station (BS) can be significantly improved. In [29], an opportunistic retransmission protocol PRO is proposed to cope with the unreliable wireless channel. Implemented at the link layer, PRO leverages on the path loss information Receiver Signal Strength Indicator (RSSI) to select and prioritize relay nodes. By assigning the higher priority relay a smaller contention window size, the node that has higher packet delivery ratio to the destination will be preferred in relaying. With respect to the impact of mobility, Wu et al. [30] investigate the WiFi connectivity for moving vehicles, with focus on the cooperation among BSs. BSs that overhear a packet but not its acknowledgment probabilistically relay the packet to the intended next hop. With the help of auxiliary BSs, the new protocol performs much better than those schemes with only one BS participating in the communication even if advanced link prediction and handover methods are involved. However, due to the lack of strict coordination between BSs, false positives and false negatives exist. While the aforementioned two schemes deal with the issues in WLANs, the aut...

...e also considers the incentive of the source node, but it has a major difference from the scheme in [20]. Our scheme has rigorous analysis of incentives while the scheme in [20] does not. Recently in =-=[31]-=-, Wu et. al. propose an incentive compatible opportunistic routing scheme. Their focus is on making sure the nodes to faithfully follow the protocol (i.e., reporting link loss and so on) in the proces...

In [1], =-=[14]-=-, [17], [18], authors also present their study of incentive issues in wireless networks. In [12], authors show that shared history based incentives can overcome the scalability problem of private hist...

...e cooperation problems in wireless networks. There are two major approaches: route selection based approach and packet forwarding based approach. The route selection based approaches (e.g., [3], [40]–=-=[42]-=-, [45]) calculates the lowest cost path despite of the fact that selfish nodes can make false claims about their costs. Most works in the category only work when there are contemporaneous end-to-end r...

Recently, Wu et al. =-=[9]-=- designed protocols to stimulate mesh nodes’ incentives to truthfully measure the link loss probabilities and follow MORE-based opportunistic routing protocols. However, Wu et al.’s work cannot guaran...
