RAR:Replication Adaptive Routing in Oceanic Wireless Networks

oceanic wireless networks, delay/disruption tolerant networks, wireless routing protocols

Due to the intermittent connectivity of oceanic wireless communication, traditional connection-oriented TCP/IP protocols have to stop transmission because of connection interruption, which greatly reduces the throughput of oceanic wireless communication. And due to the heterogeneity of oceanic wireless networks, existing wireless network protocols cannot directly apply to oceanic wireless networks. Therefore, we designed a Replication Adaptive Routing (RAR) protocol for oceanic wireless networks, considering the heterogeneity of oceanic wireless networks, as well as the characteristics of oceanic wireless communication. To evaluate the performance of RAR, we implement RAR on a testbed consisting of over 20 wireless nodes. The experimental results have shown that RAR effectively improves data transmission rate and greatly reduce transmission delay, compared with existing TCP/IP protocols.
