Conventional networks treat packets drop as an indication of congestion and employ the end devices to mitigate congestion. This may impose restrictions on network performance with the absence of comprehensive view of network. To solve these problems, this paper proposes an intelligent congestion control algorithm based on the global characteristics of software defined network architecture. The controller monitors the global operating state of network and evaluates instant congestion quality of backup paths in network by fuzzy logic. Combing with reinforcement learning, the controller evaluates the rerouting decisions under current network circumstances and chooses the optimal forwarding path which meets the traffic load requirement to forward flows. Experiments shows that the mechanism can significantly enhance network performance especially when network is under heavy load.","PeriodicalId":330766,"journal":{"name":"2019 IEEE 11th International Conference on Communication Software and Networks (ICCSN)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129794225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In connection with this, data encryption turns out to be an essential part of the secure communication of this important information. In this paper, a simplified method of encryption of data in blocks using the logical XOR and shift operations, and Radix64 for encoding and decoding the data is introduced.

Due to the mobility of wireless nodes, network topology changes frequently. Consequently, routing protocols used in mobile ad-hoc networks must be adaptive. The routing protocols enabling data transfer within MANETs are classified into reactive, proactive, and hybrid protocols. Proactive routing protocols, such as the Destination Sequenced Distance Vector, are table- driven protocols that use stale paths in case of broken links which causes loss of data in the network. This research study will explore A Neighbor Coverage Multipath DSDV as a potential solution for data loss by finding alternate routes to the destination when a link is broken. Simulations have been carried out for the three routing protocols: DSDV, FSR, and the proposed NCMDSDV. Results showed that the proposed routing protocol has better efficiency compared to DSDV and FSR routing protocols.","PeriodicalId":330766,"journal":{"name":"2019 IEEE 11th International Conference on Communication Software and Networks (ICCSN)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133473426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Good frequency utilization and power utilization means that MSK is suitable for UAV data link.

This paper introduces an improved structure based on MSK multi-symbol non-coherent detection algorithm, which is simplified multi-symbol non-coherent detection (SMND) receiver. The performance simulations show that the theoretical limit performance of the receiver is comparable to that of a coherent receiver and the receiver is significantly better than a conventional non-coherent receiver. In AWGN channel where the bit error rate (BER) is 10–5, the performance of the SMND receiver in this paper is superior to one-bit differential by 2.5 dB, superior to the non-coherent envelope detection by 3.2 dB, and achieves only loss of 0.3 dB comparing to the theoretical limit of coherent demodulation. Furthermore, the SMND algorithm has good performance of anti-frequency offset and anti-bit timing error.","PeriodicalId":330766,"journal":{"name":"2019 IEEE 11th International Conference on Communication Software and Networks (ICCSN)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133616086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Software Defined Networking (SDN) technology is applied to dynamically manage and orchestrate end-to-end network resources as per application needs and network condition and scenario. A structured approach is applied to implementing Machine Learning (ML) techniques within the network. A ML approach is intended to be used to autonomously learn the best management strategy for a given application and best fulfill its requirements. The framework is based on the combined SDN and ML approach, combining information obtained from both the SDN North Bound Interface (NBI) and South Bound Interface to assess both the network and application state and condition. A module built on the SDN controller uses this information to correlate network level metrics with application condition. This module will learn how the features of the network effect the application condition. This information is then used to make decisions with regards to network resources for the application. The framework is structured into three main modules: data collection and aggregation, network/application learning and network management with prediction. The proposed framework is intended to be used for investigation into link types and their effects on end-to-end path selection for application flows in SDN. This is essential for future networks as more diverse applications are expected to enter the mobile domain with each application flow traversing a range of link types.","PeriodicalId":330766,"journal":{"name":"2019 IEEE 11th International Conference on Communication Software and Networks (ICCSN)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132505970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The map generated by UAV remote sensing images is expected to be widely used in resource monitoring, post-disaster reconstruction and so on. Tile cache is an important way to speed up real-time loading of tile map. In order to accelerate the tile loading of UAV map, we take advantage of data locality principle and user behavior to build Hilbert coding index for each level in the tile pyramid. Then, we propose a neighborhood prefetching cache strategy, which is analyzed from the two dimensions of width and depth on the basis of Hilbert coding index. Compared with a simple strategy taking single tile as cache granularity, this caching strategy improves cache hit ratio and reduces average response time of tiles significantly. Meanwhile, Redis as the cache database, which not only supports the persistence of memory data, but also has the advantages of high development efficiency and strong scalability.","PeriodicalId":330766,"journal":{"name":"2019 IEEE 11th International Conference on Communication Software and Networks (ICCSN)","volume":" 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113946283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
