We develop a cooperative decode-and-forward strategy of distributed Source-Relay network coding for a three-node relay model, in which Relay and Source both send their own messages to Destination. First, we present a cooperative communication protocol to achieve decode-and-forward capacity by leveraging transmit rates between Source and Relay and designing distributed Source-Relay network coding accordingly. After-wards, multi-dimension Low-density parity-check (LDPC) code is constructed as a layered structure, where Source LDPC, Relay LDPC, and network LDPC code are organically integrated to realize a distributed design. Our design randomly embeds network-coded message into the layered structure as effective extra checks offering side information for both Source and Relay. Based on derivation of the algebraic relationship between constituent codes, a good multi-dimension LDPC code profile is generated. Meanwhile, network coding complexity maintains linear to the block length. The coding scheme is demonstrated to approach decode-and-forward capacity and still provides effective spatial diversity.

The usage of network devices equipped with multiple radio access technologies is a promising way to achieve high throughput, low latency, and resilient wireless communication. However, classical scheduling approaches cannot realize the full potential because packet loss on one radio interface can result in resources on the other interfaces to remain unused. This is particularly a problem in situations with asymmetric link data and loss rates. We show that the performance of a multi-RAT system can be significantly improved by the application of intra-flow network coding where the loss of a single or multiple coded packets on one interface does not result in blockage and hence unused radio resources on some other interface. Moreover, it is less sensitive to transmission failures on the backward direction used by automatic repeat request (ARQ). Results from simulations reveal that our approach is able to outperform a classical approach in terms of throughput by factor of up-to 4.4× in certain scenarios.

Use of millimeter waves (mmWave) and other high frequency bands are expected to be a crucial part of 6G networks. Performance analysis of mmWave communication scenarios and modeling of various protocols in those situations have demonstrated the burst-error nature of mmWave channels. With the increasing adoption of such communication standards operating in lossy conditions, advanced communication techniques have started to be explored within the context of bursty channels. network coding is one such widely utilized technology for achieving high-throughput and reliable communication over lossy channels. This work focuses on modeling the TCP and TCP/NC protocols within a burst-error scenario, mainly focusing on the presence of time-out events as sources of window size reduction. We provide a detailed analysis of throughput and congestion control, along with their formulation and simulated results. We show that, even with the presence of time-out events, TCP/NC outperforms standard TCP by over an order of magnitude.

network coding has been diagnosed as an approach to beautify the overall performance of access networks. In such networks, community coding permits a sure level of fault tolerance as each communication node can feature as a transmitter and a receiver. By means of enabling the nodes to perform simultaneous encoding and interpreting operations, network coding can ensure a reliable verbal exchange over wireless gets admission to the network even in the presence of unreliable links and nodes. It could be accomplished by sending redundant records across diverse parts of the network to boost the probability of recuperating the facts in case of any loss. Moreover, network coding can reduce the overhead generated by means of the retransmission of misplaced packets. It may lead to an advanced throughput of the communication. Wireless, due to its flexibility in managing screw-ups, network coding is a powerful technique to construct robust and fault-tolerant entries to networks.

The continuous rise of bandwidth-demanding and low-latency required services such as high-definition video streaming, along with the growing popularity of multi-homing mobile terminals, has encouraged research into concurrent transmission technologies in heterogeneous networks. Concurrent transmission over heterogeneous networks effectively aggregates bandwidth resources, improving transmission throughput. However, it also faces challenges such as the great dissimilarity of each path leading to head-of-line blocking issues at receiver side. Moreover, in scenarios involving concurrent transmission of multiple services over heterogeneous networks, allocating network resources from the perspective of a single service may lead to the competition for network resources of each service and result in each service failing to meet its Qos. Therefore, this paper proposes a method for multi-service concurrent transmission control over heterogeneous networks based on adaptive network coding(NC). First, the algorithm allocates suitable network resources based on each service’s Qos and path characteristics. Then it utilizes the A3C reinforcement learning algorithm to make real-time decisions through interaction with the network environments, determining the optimal encoding density for each encoding packet group, which reduces the decoding delay *** results show that the proposed algorithm can improve application transmission speed and reduce delivery delay, effectively enhancing user experience.

This paper specializes in the layout and optimization of adaptive community coding algorithms for WiFi networks. The goal of those algorithms is to maximize the performance of network transmissions at the same time as heading off collisions and losses. We analyze the performance of numerous current network coding algorithms, examine their strengths and weaknesses and advocate techniques to optimize their performance. We also increase and compare new algorithms based on the adaptive network coding method. Those algorithms are designed if you want to mechanically adapt to the environment and take full benefit of the available assets to maximize the overall network’s performance. The results of our simulations endorse that the proposed adaptive network coding algorithms outperform conventional network coding algorithms in phrases of both throughput and latency. We further propose an optimized model of our adaptive network coding algorithms and evaluate its performance to that of the unique algorithms. Our results demonstrate significant performance profits in terms of both throughput and latency.

This research explores the challenge of dynamic environment object detection. Changing environment factors adversely affect the feature detection and robustness of the model. The approach proposed homogenizes the principles from Information Theory and network coding to enhance the overall final matching accuracy and robustness of the model. The effectiveness is improved by systematically using the concepts of entropy, mutual information, Principal Component Analysis, Random Linear network coding and Support Vector Machines. The developed framework maintains distinctive feature recognition and classification performance with rapid environment changes. The proposed and the baseline model is run in python using OpenCV for obtaining the experimental result. By including these robust feature extraction techniques along with Scale-Invariant Feature Transform, in dynamic environments, the model achieves a final matching accuracy of 72.4% and an F1-score of 76.1%. In contrast, the baseline model achieves a final matching accuracy of 43.8% and an F1-score of 44%. The improvement in performance shows the model's enhanced resilience and robustness with the changing environmental conditions, contributing valuable prospects for real-time applications where environmental variability is a factor to be considered.

Physical-layer network codes for consensus-testing (CT) via a relay are proposed, where each of two parties knows a message and can find out if all messages are equal, e.g. as an integrity check in a decentralized storage system or the control of mobile autonomous robots. By assumption, the encoders cannot randomize. The proposed codes achieve the CT capacity for channels with a memoryless uplink multiple-access channel that is a binary adder channel or a pair of q-ary symmetric or erasure channels. There, the capacity of noiseless uplinks can always be achieved, by using generalized deterministic identification (ID) codes for the uplink, testing consensus at the relay, and broadcasting the one-bit result using zero rate. For pairs of Gaussian channels and Gaussian adder channels, the capacity bounds equal those known for ID over certain noiseless uplinks, where the code sizes scale superexponentially in the block length. Using a recent derandomization result for decoders, it is shown that for general channels, the ID capacity of certain noiseless uplinks upper-bounds the CT capacity. In contrast, both for transmission coding for the uplink and additive linear network codes, the asymptotically achievable code sizes and necessary block lengths are shown to be suboptimal.
