This paper investigates the intrinsic relationship between secure network coding and secure cloud storage. We propose a novel homomorphic signature scheme and then illustrate a method to construct the network coding based secure cloud storage (NCSCS) protocol, wherein the security of the homomorphic signature scheme is the foundation of the NCSCS protocol. By employing network coding and homomorphic signature technique, the proposed NCSCS system can serve as both cloud service provider and router of a communication network at the same time, where the public auditing of the outsourced data is enabled. Finally, we perform the simulation of the proposed protocol and evaluate its performance. The security and efficiency can be validated from the simulation results.

The mobile delay tolerant network has some features results in transmit message is limited in one touch. In order to transmit more messages in one touch, network encoding technology is introduced. It effectively improves this problem. The mobile devices in the mobile delay tolerant network have the advantages of mobility, portability, but there are also problems, such as: limited energy, node sociality. When the energy of the node in the network is exhausted, it will affect the performance of the network. Therefore, the introduction of energy management strategies into the network coding routing strategy is of great significance to the performance improvement of the mobile delay tolerant network. In this paper, through the ONE to achieve the routing strategy proposed in this paper, and then compared with some existing routing strategy. Experimental results show that the routing strategy proposed in this paper can effectively improve the rate of message delivery, reduce delay, and reduce network overhead.

network coding is widely adopted in ad hoc networks to enhance the network throughput while few attention has been paid on applying it in device-to-device (D2D) networks. In this paper, we consider a relay-assisted D2D network with inter-session network coding, where multiple D2D users coexist in an underlaying manner. We aim to maximize the sum throughput via joint power and resource group allocation, which is formulated as a mixed integer programming problem. To solve this problem, an iterative algorithm with low complexity is accordingly proposed. Simulation results verify the effectiveness and superiority of the proposed algorithm compared with existing algorithms.
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 ver...

Transceiver duty-cycling (DC) is a popular technique to conserve energy in a wireless sensor network (WSN). In our previous work [SoICT 2016: 187-194], we introduce a modeling approach for wireless networks of time-varying topology whose nodes duty cycle periodically. By switching nodes (transceivers) OFF, we however inescapably reduce the attainable throughput to a certain degree. For the throughput reduction problem, in this paper, we consider the application of XOR-pairwise network coding (NC) approach to by combining packets destined for distinct users. Through numerous simulation studies and in comparison with the perflow rates produced by the optimization step without NC, we found that the NC is really efficient and applicable to arbitrary topology DC WSNs for improving the total throughput of the networks although it may change the maxmin rate allocation to individual flows.

Based on the characteristics of vehicle network and cooperative network coding technology, the vehicle two-way communication system is studied. The outage probability is derived by building the vehicle two-way communication system model, the relationship between the distance, the speed, the communication time and the interruption performance are analyzed. The maximum value of all the minimum outage probabilities at all times in the communication process is the optimized object. According to the optimized object, the optimal power allocation scheme is proposed, and the optimal power allocation factor is deduced. Compared with the average power allocation, the scheme can obtain better system interrupt performance. The simulation results show that the optimal allocation factor is close to the theoretical value and is superior to other allocation schemes.

With recent advances in wireless communications, vehicular networks are envisioned as a promising paradigm on achieving breakthroughs in transportation safety, efficiency, and sustainability. This work investigates data broadcast via Infrastructure-to-Vehicle (I2V) communication by exploiting the vehicular caching and network coding for enhancing bandwidth efficiency of the road-side unit (RSU). Specifically, we present an architecture for providing real-time data services via I2V communication in the service range of a RSU. Then, we investigate the problem of cache-aided data dissemination with network coding and prove that it is NP-hard. Further, we propose a memetic algorithm, which consists of a binary vector representation for encoding solutions, a fitness function for solution evaluation, a set of operators for offspring generation, a local search method for solution enhancement and a repair operator for fixing infeasible solutions. Finally, we build the simulation model and give a comprehensive performance evaluation to demonstrate the superiority of the proposed solution.

A key problem in network coding (NC) lies in the complexity and energy consumption associated with the packet decoding processes, which hinder its application in mobile ad hoc networks (MANETs). Sliding-window network coding is a variation of NC that is an addition to TCP/IP and improves the throughput of TCP on MANETs. In this paper, we propose an Adaptive Length Sliding Window-based network coding for Energy Efficient algorithm in MANETs (ALSW-NCEE). The performance of this ALSW-NCEE is studied using NS2 and evaluated in terms of the network throughput, encoding overhead, energy consumption, and energy efficiency when packet is transmitted. The simulations result shows that the ALSW-NCEE with our proposition can significantly improve the network throughput and achieves higher diversity order.

In this paper, we consider a real-time multimedia broadcasting system with systematic network coding over packet erasure channel. We focus on studying a theoretical decoding error rate and shows that it is a function of encoding number, packet loss rate of wireless channel and code rate of system. Specifically, we show that the decoding error rate is inversely proportional to the encoding number if packet loss rate is low, while it is proportional to encoding number if packet loss rate is high. The simulation results confirm theoretical analysis.
