Reliable social connectivity and transmission of data for popular nodes is vital in multihop ad-hoc social networks (ASNETs). In this networking paradigm, transmission unreliability could be caused by multiple social applications running on a single node. This leads to contentions among nodes and connection paths. In addition, congestion can be the result of multiple senders transmitting data to a single receiver and every sender waiting for a positive acknowledgment to move on. Therefore, the traditional Transmission Control Protocol (TCP) performs poorly in ASNETs because the available bandwidth is shared among nodes using round-trip time, and the acknowledgment is provided individually to every data packet. To solve these issues, we propose a technique called Overhead Control with Reliable Transmission of Popular Packets in Ad-Hoc Social Networks (RTPS), which improves transmission reliability by assigning bandwidth to users based on their popularity levels: Extra bandwidth is assigned to the nodes with higher popularity, and their acknowledgments are sent with higher priority. In addition, RTPS further reduces contentions and packet losses by delaying acknowledgment packet transmissions. Our detailed investigations demonstrate the excellent performance of RTPS in terms of throughput latency and overhead with different hop distances and different numbers of concurrent TCP flows.
