abstract = {Many envisioned applications for the Tactile Internet require latencies 

that cannot be achieved by current wireless networks. In this paper, we 

present a method to optimize the reliability of a live stream using 

multiple paths. Compared to other approaches, our method does not rely on 

feedback to achieve the reliability and thus does not add delay for 

retransmission attempts. We use the diversity of multiple paths to 

compensate for the loss of capacity in individual paths. By using an FEC 

code to generate redundant data the transmission is more robust against 

fluctuations in capacity of single paths. We present an optimization 

problem to find a rate allocation for the paths that minimizes the 

interruptions of the stream. The performance is evaluated in an emulated 

network based on real-world measurements. The evaluation shows that the 

theoretical values can be achieved with a small margin. The optimized 

allocation of rates to the paths increases the reliability by up to 

12%.With coding the reliability can be increased by up to 20%, depending 

on the code rate.},

abstract = {We use random linear network coding (RLNC) based scheme for multipath communication in the presence of lossy links with different delay characteristics to obtain ultra-reliability and low latency. A sliding window version of RLNC is proposed where the coded packets are generated using packets in a window size and are inserted among systematic packets in different paths. The packets are scheduled in the paths in a round robin fashion proportional to the data rates. We use finite encoding and decoding window size and do not rely on feedback for closing the sliding window, unlike the previous work. Our implementation of two paths with LTE and WiFi characteristics shows that the proposed sliding window scheme achieves better latency compared to the block RLNC code. It is also shown that the proposed scheme achieves low latency communication through multiple paths compared to the individual paths for bursty traffic by translating the throughput on both the paths into latency gain.},
