Marine fishery production safety has always been a livelihood issue of high concern to government departments at all levels in China. With the construction of marine informatization, a large number of fishing vessels have entered the Vessel Monitoring System (VMS). The massive, highly concurrent, and continuous track data generated by these vessels has posed great challenges to real-time data distribution. To cope with low distribution efficiency in the original data distribution system, this paper proposed a data distribution model based on the combination of network coding and UDP, which improves both reliability and efficiency of data distribution. In order to further enhance the efficiency of data distribution, a Codeword Distance Priority Protocol based on Buffer Map (CDPPBM) was added to the proposed model for the concentration of innovative codewords in the network, thereby increasing the effectiveness of data received by nodes. Experimental results show that the protocol proposed in this paper improves the data distribution efficiency by about 75% on average, compared with the LT code. The influence of data block size on network coded data distribution system is not involved in the previous work. Therefore, this paper discusses the Block to Piece Protocol (BPP) for large files, divides large files into fixed sizes equally, and distributes n data blocks multiple times to find the optimal piece size. The experimental results show that there is an optimal n for large files of different sizes, which can maximize the efficiency of data distribution.

“…Random linear network coding was first introduced in information theory [21] and it has been used in P2P content distribution to improve system performance in terms of download time and throughput [22] [23]. Each peer can able to generate linearly coded blocks using the block it receives from its different incoming link and transmits the generated coded blocks to its downstream peers in network coding based P2P network.…”

Most of the existing P2P content distribution schemes carry out a random or rarest piece first content dissemination procedure to avoid duplicate transmission of the same pieces of data and rare pieces of data occurring in the network. This problem is solved using peer-to-peer (P2P) content distribution based on network coding scheme. Network coding scheme uses random linear combination of coded pieces. Hence the above stated problem is solved ease and simple. Our proposed mechanism uses network coding mechanism in which several contents of same message is grouped into different group and coding operation is performed only within the same group. The interested peers are also divided into several groups with each group have the responsibility to spread one set of contents of message. The coding system is designed to assure the property that any subset of the messages can be utilized to decode the original content as long as the size of the subset is suitably large. To meet this condition, dynamic smart network coding scheme is defined which assures the preferred property, then peers are connected in the same group to send the corresponding message, and connect peers in different groups to disseminate messages for carrying out decoding operation. Moreover, the proposed system is readily expanded to support topology change to get better system performance further in terms of reliability, link stress and throughput. The simulation results prove that the proposed system can attain 20-25% higher throughput than existing systems, good reliability, link failure and robustness to peer churn.

“…With the emergence of wireless networks like Wireless Sensor Network (WSN) and Mobile Ad Hoc Network (MANET), there is ever growing list of applications of such networks. There are multimedia content distribution systems that work on top of MANET and other such wireless networks [1]. In any application where there is data transfer among nodes in the network, security is very important.…”

Moving Target Defence (MTD) became an important research area in the wake of increased cyber security threats. As the attackers are gaining knowledge on existing methods, it is essential to have more dynamic approach that can defeat plans of attackers. As improving systems with higher level of security is a never ending process, MTD has got significance in military and other applications where critical digital infrastructure needs to be protected from adversaries. When attack surface is dynamically evolving with mutation strategy, it can lead to realization of MTD. As MTD increases complexity and uses dynamic encryption mechanism, the attack surface evolves from time to time confusing attacker. Traditional approaches like AES and DES alone will have their limitations. However, when they are used along with the concept of MTD strategies, it is possible to provide highly secure environment. In this paper, we proposed a framework with an underlying algorithm which ensures MTD with dynamically evolving attack surface and dynamic encryption standards based on DES. The experimental results revealed that the proposed scheme is effective and shows improved performance over its predecessor.
