This paper presents an adaptive retransmission scheme to overcome video packet losses in content-centric wireless networks. Because of in-network caching, the round-trip time (RTT) may fluctuate significantly. A new timeout estimation algorithm is proposed to quickly adjust the timeout value. The sequential hypothesis testing methodology is suggested to provide theoretical bounds on the probabilities of false-positive and false-negative detection rates. By considering the reasons for packet losses, the scheme adaptively controls its retransmission window size. Experimental results demonstrate that the proposed scheme efficiently recovers packet losses under various network conditions.
