Analysis of latency for reliable end-to-end batch transmission in multi-rate multi-hop wireless networks

We present an analytical model to analyze latency for reliable end-to-end batch transmission in a multi-hop wireless network using multi-rate transmission at each hop. The end-to-end reliability is achieved through hop-level error recovery based on an automatic repeat request (ARQ) protocol with unlimited persistence. The multi-rate transmission in the radio link is achieved through adaptive modulation and coding (AMC). We derive complete statistics (i.e., probability mass function) for the end-to-end latency. The analytical results are validated through simulations. The proposed model would be useful to analyze and optimize reliable end-to-end protocol (i.e., transport layer protocol) performance in multi-hop wireless networks.
