Abstract

Traditional transport protocols have been designed to perform end-to-end transmission and retransmission. In terms of choosing the optimal transmission window, previous works suggest a value based on the bandwidth-delay product (BDP). For wireless networks, the BDP value is related to the round-trip hop length. However, there exists a new class of transport protocols that use intermediate caching which can drastically improve the performance even in the presence of high packet error rates. In this paper, we show that using a window size related to the BDP could lead to sub-optimal performance for caching-based protocols. Furthermore, we present a heuristic for choosing the optimal transmission window such that the optimal value is related to the average cache size in the intermediate nodes.
