These networks utilize ad-hoc routing protocols to interconnecting all nodes. Each peer forwards data for other nodes on the basis of network connectivity and a set of conventions that is determined by the routing protocol. Still, these protocols fail to protect legitimate nodes against several types of selfish and malicious activity. Thus, trust and reputation schemes are integrated with pure routing protocols to provide secure routing functionality. In this paper we propose ModConTR - a modular and adaptable trust and reputation-based system for secure routing. The system is composed of 11 different components which can be configured at runtime to adjust to each application's security and performance requirements. Presented work includes three possible configurations of ModConTR, considering ultra-lightweight, low-cost and lightweight implementations. Moreover, predefined configurations permit the implementation of the reasoning process for well-known secure routing protocols. Thus, we present a security and performance analysis for each of the components, including a comparative analysis of 10 complete trust and reputation schemes under identical attack scenarios. ModConTR is implemented using the NS2 simulator and is integrated with the DSR routing protocol.","PeriodicalId":412749,"journal":{"name":"2014 IEEE/ACS 11th International Conference on Computer Systems and Applications (AICCSA)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127322386","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}

Intruders can exploit the large amount of cloud resources for their attacks. Most of the current security technologies do not provide the essential security features for cloud systems such as early warnings about future ongoing attacks, autonomic prevention actions, and risk measure. This paper discusses the integration of these three features to our Autonomic Cloud Intrusion Detection Framework (ACIDF). The early warnings are signaled through a new finite State Hidden Markov prediction model that captures the interaction between the attackers and cloud assets. The risk assessment model measures the potential impact of a threat on assets given its occurrence probability. The estimated risk of each security alert is updated dynamically as the alert is correlated to prior ones. This enables the adaptive risk metric to evaluate the cloud's overall security state. The prediction system raises early warnings about potential attacks to the autonomic component, controller. Thus, the controller can take proactive corrective actions before the attacks pose a serious security risk to the system. According to our experiments, both risk metric and prediction model have successfully signaled early warning alerts 39.6 minutes before the launching of the LLDDoS1.0 attack. This gives the system administrator or an autonomic controller ample time to take preventive measures.","PeriodicalId":412749,"journal":{"name":"2014 IEEE/ACS 11th International Conference on Computer Systems and Applications (AICCSA)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114698284","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}

Several qualitative and quantitative factors are considered leading to targeted professional growth of an organization to evaluate the performance, such as acquiring research grants, research profile, student evaluation, publications, academic responsibilities etc. However, to quantify such information is a difficult task. Usually standard “Key Performance Indicators” (KPIs) are used to evaluate bare level workload of a faculty, however gauging quality always remain a challenge. In this paper, we propose an ontology based faculty performance evaluation system where the ontology is used to conceptualize the qualitative factors of the faculty as well as the set of rules that together make a system. The Semantic Web Rule Language (SWRL) is used to represent rules in ontology and built-in reasoning support help to deduce new knowledge. The presented work has been tested by applying it on real data set of a Public Sector University in Pakistan, and analyzes the strengths and weaknesses of the proposed system. It must be mentioned that the use of ontology makes the system easily modifiable due to the availability of the sophisticated ontology editors and APIs as well as provides complete automatic system.","PeriodicalId":412749,"journal":{"name":"2014 IEEE/ACS 11th International Conference on Computer Systems and Applications (AICCSA)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116833435","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 this direction, orthogonal moments have proved their performance since the image can be reconstructed from its descriptor. However, these conventional moments deal only with binary and gray-level images. Recently, the algebra of quaternions have been widely used in combination with these moments in order to describe color images. In this paper, we introduce the quaternion Disc- Harmonic moments (QDHMs) as an extension of the conventional Disc-Harmonic moments (DHMs) for describing 2D color shapes. The conventional DHMs were inspired by the spherical harmonics which use orthogonal basis functions and are known for their rotation-invariance property. Experiments on images extracted from the COIL-100 database were conducted in order to evaluate the performance of our descriptor. First, we have fixed some parameters that are the maximal order, the measure of similarity and the color space. Second, tests on photometric transformations robustness are provided. Finally, the discriminative power of the QDHMs based on recall-precision criterion is compared to the conventional disc-harmonic moments and the existing orthogonal quaternion-based moments.","PeriodicalId":412749,"journal":{"name":"2014 IEEE/ACS 11th International Conference on Computer Systems and Applications (AICCSA)","volume":"72 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130513447","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}

Application Response Time is the key performance measure in WiMAX and WLAN Network Quality of Service (QoS). The WiMAX network does not provide sufficient QoS with respect to Application Response Time. Wavelength Division Multiplexing (WDM) has emerged as the promising technology to meet the ever-increasing demand for bandwidth In this paper, we developed a Distributed Client-Server Model to improve QoS with respect to Application Response Time in the Fixed WiMAX and WLAN Network in order to enhance the services that are provided to the end users. The new distributed Client-Server model was simulated in OPNET modeler 16.0 with multiple Base Stations (BSs), Subscribers Stations (SSs) and some Server BSs selected by the Nearest Neighborhood Algorithms using Orthogonal Frequency Division Multiplexing (OFDM) techniques and compared with the existing Centralized model using Frequency Division Multiplexing (FDM) techniques. The simulation results obtained for the application response time of the proposed Client-Server model show an improvement in network performance.","PeriodicalId":412749,"journal":{"name":"2014 IEEE/ACS 11th International Conference on Computer Systems and Applications (AICCSA)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123978775","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}
