To tackle the non-convexity of the secure energy efficiency maximization (SEEM) problem, we employ branch-and-reduce-and-bound (BRB) approach to obtain the globally optimal solution. It is observed that the BRB algorithm suffers from highly computational cost, its globally optimal solution is importantly served as a benchmark for the performance evaluation of the suboptimal algorithms. This motivates us to develop a low-complexity approach using the well-known zero-forcing (ZF) technique to cancel the wiretapped signal. In ZF based method, the SEEM problem can be transformed to a concave-convex fractional one and, then, be solved by the combination of the Dinkelbach and bisection search algorithm. Simulation results reveal that the ZF based method can converge fast and obtain a sub-optimal performance in compared with the optimal solution of the BRB method. The ZF based scheme also outperforms the conventional secrecy rate maximization precoder design in terms of the energy efficiency.","PeriodicalId":347057,"journal":{"name":"2016 3rd National Foundation for Science and Technology Development Conference on Information and Computer Science (NICS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127210277","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}

These networks allow monitoring processes to be conducted remotely, in real-time and with minimal human intervention. Water quality monitoring is essential to the provision of clean and safe water. In Botswana, Water Utilities Corporation (WUC), has adopted a conventional like process that employs several independent hand held meters for sampling different water quality parameters manually. However, this process has proved to be ineffective since it is expensive, time consuming, requires considerable human resource capacity and lacks real-time results to promote proactive response to water contamination. In this work, an integrated WSN based solution that employs Libelium's Waspmote platform has been developed. The sensor node is based on ATMEL's ATmega 1281 8-bit low power microcontroller which can operate for more than a year without recharging its battery. Results have shown that the proposed system managed to sample associated water quality parameters in real time with the same accuracy as currently adopted methods. In addition, the system is autonomous, easy to install, highly scalable and has a relatively high sampling rate which improves the temporal resolution of the monitoring process.","PeriodicalId":347057,"journal":{"name":"2016 3rd National Foundation for Science and Technology Development Conference on Information and Computer Science (NICS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134464263","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 architecture allows multiple cooperating DDoS mitigation techniques to classify incoming network packets. The proposed architecture consists of two separated partitions: static and dynamic. The static partition includes packet pre-processing and post-processing modules while the DDoS filtering techniques are implemented on the dynamic partition. These filtering techniques can be implemented by either hardware custom computing cores or general purpose soft processors or both. In all cases, these DDoS filtering computing cores can be updated or changed at runtime or design time. We implement our first prototype system with Hop-count filtering and Ingress/Engress filtering techniques using Xilinx Virtex 5xc5vtx240t FPGA device. The synthesis results show that the system can work at up to 116.782MHz while utilizing about 41% LUTs, 47% Registers, and 53% Block Memory of the available hardware resources. The system achieves the detection rate of 100% with the false negative rate at 0% and false positive rate closed to 0.74%. The prototype system achieves packet decoding throughput at 9.869 Gbps in half-duplex mode and 19.738 Gbps in full-duplex mode.","PeriodicalId":347057,"journal":{"name":"2016 3rd National Foundation for Science and Technology Development Conference on Information and Computer Science (NICS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116820757","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}
