In most Delay Tolerant Network (DTN) applications, mobile nodes utilize WiFi radios to obtain local information and transmit data. One bottleneck on DTN delivery performance is the short communication range of the WiFi radio. Rather than designing efficient protocols on WiFi based DTN, the authors propose a novel dual-radio architecture by adding a long-range low-bitrate Eagle Eye (EE) radio on every node. This EE radio can "See" real-time movement information of nodes in a significantly large range, and so much early scheduling can be done with this radio when compared with WiFi which is still in charge of data transmissions.
