For a future scenario where everything is connected, cognitive technology can be used for spectrum sensing and access, and emerging coding technologies can be used to address the erasure of packets caused by dynamic spectrum access and realize cognitive spectrum collaboration among users in mass connection scenarios. Machine learning technologies are being increasingly used in the implementation of smart networks. In this paper, after an overview of several key technologies in the cognitive spectrum collaboration, a joint optimization algorithm of dynamic spectrum access and coding is proposed and implemented using reinforcement learning, and the effectiveness of the algorithm is verified by simulations, thus providing a feasible research direction for the realization of cognitive spectrum collaboration.

“…The deterministic property, owing to its simplicity in both implementation and analysis of the baseline recoding scheme, has induced many research results, for example, the discrete first-order stochastic dominance [ 74 , 75 ] property of the rank distributions on line networks was investigated in Reference [ 64 ], and the batch transfer matrices were shown to be diagonalizable in Reference [ 43 ]. Also, the protocol BATS-pro1 [ 41 ] and FUN codes [ 50 , 51 ] are also based on the baseline recoding scheme.…”

“…There are techniques other than RLNC for generating recoded packets, for example, systematic recoding [ 5 , 41 ]. It is known that the design of the inner code has impact on the achievable rates [ 41 ], for example, the advanced recoding schemes in References [ 30 , 42 , 43 , 44 ]. On the other hand, Reference [ 41 ] also suggested that burst packet loss can reduce the advantage of using BATS codes.…”

Internet of Things (IoT) connects billions of everyday objects to the Internet. The mobility of devices can be facilitated by means of employing multiple wireless links. However, packet loss is a common phenomenon in wireless communications, where the traditional forwarding strategy undergoes severe performance issues in a multi-hop wireless network. One solution is to apply batched sparse (BATS) codes. A fundamental difference from the traditional strategy is that BATS codes require the intermediate network nodes to perform recoding, which generates recoded packets by network coding operations. Literature showed that advanced recoding schemes and burst packet loss can enhance and diminish the performance of BATS codes respectively. However, the existing protocols for BATS codes cannot handle both of them at the same time. In this paper, we propose a paradigm of protocol design for BATS codes. Our design can be applied in different layers of the network stack and it is compatible to the existing network infrastructures. The modular nature of the protocol can support different recoding techniques and different ways to handle burst packet loss. We also give some examples to demonstrate how to use the protocol.
