Mobile Femtocells can be deployed in public transportation vehicles such as trains, buses or private cars that form its own cell inside vehicles to serve vehicular and mobile User Equipments. This study intends to help cell-edge users to have better signal strength. An investigation into Long Term Evolution cell-edge users' performance is being conducted by investigating the deployment of Mobile Femtocells in LTE system. The throughput for cell edge users can be improved by deploying Fixed/Mobile Femtocells. This paper is considering several scenarios namely; Fixed Femtocells with Fixed users, Mobile Femtocells with fixed users, Fixed Femtocells with mobile users and Finally Mobile Femtocells with mobile users. The achieved results via Matlab simulation showed that Mobile Femtocells' users have enjoyed better Quality of Services than Fixed Femtocells' users. The improved performance has been noticed through the improvement of the Mobile Femtocells UEs' spectral efficiency, throughput and SINR over the Fixed Femtocells' users.","PeriodicalId":200083,"journal":{"name":"Second International Conference on Future Generation Communication Technologies (FGCT 2013)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127098848","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 paper, we present new results on performance of IPSec using 7 encryption systems for both IPv4 and IPv6 using Windows 7 and wireless network access. For the system studied, enabling IPSec results in approximately 60%(IPv4) and 48%s(IPv6) lessTCP throughput compared to open system. Among encryption mechanisms, 3DES-SHA provides the highest TCP bandwidth for IPv4, while 3DES-MD5 gives the best result for IPv6. We also provide the results for UDP.","PeriodicalId":200083,"journal":{"name":"Second International Conference on Future Generation Communication Technologies (FGCT 2013)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132564907","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}

While many proposal were made in the past twenty years, most of them haven't been widely used due to practical complexity. Yet the urge for modular protocol designs is still present to allow easier adoption of new algorithms within existing protocols, especially at the transport layer. In this paper, we describe a component-based design concept for protocols, where each protocol type defines a template for interacting protocol building blocks. In addition, we propose a detailed template for transport protocols that can accomodate mechanisms not available with TCP - both as an example and a design proposal of its own. With the discussion of variations of this transport protocol template, we show the benefit of this approach. In addition, we show simulatively that a specific behavior of an existing protocol configuration can be reproduced with this template.","PeriodicalId":200083,"journal":{"name":"Second International Conference on Future Generation Communication Technologies (FGCT 2013)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116665778","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}

Based on the implementation scenario, such communication might take place over a public network such as the Internet, which is based on the TCP/IP stack. However, different research working groups argue that some of these stack protocols such as the Hyper Text Transfer Protocol (HTTP) might not be suitable for constrained devices. Therefore, the IETF Constrained RESTful Environments (CoRE) WG has proposed the Constrained Application Protocol (CoAP); an application layer protocol for constrained devices in the IoTs. The CoRE WG proposed using IPSec or DTLS to secure the CoAP communication at different levels of the protocol stack. However, to investigate the feasibility of such a proposal, we use the X.805 security standard to analyze the security aspects of such implementation. The analysis highlights the main security drawbacks and hence argues of the need for a new integrated security solution.","PeriodicalId":200083,"journal":{"name":"Second International Conference on Future Generation Communication Technologies (FGCT 2013)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128528744","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}

Unlike conventional route planning tasks that are usually used for finding shortest routes, present approach uses multiple parameters and categories for describing asymmetric threats emanating from surrounding urban environments and planning routes. These parameters can be combined together to find routes with different properties. Multiple tests were performed using A* and genetic algorithm to present how different parameter values and their combinations affect output routes and how different threats can be avoided by taking those parameters into account. Tests showed that both algorithms can be used for route planning, but A* would be the recommended choice, because the probability of it finding the global optimum is larger.","PeriodicalId":200083,"journal":{"name":"Second International Conference on Future Generation Communication Technologies (FGCT 2013)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123228447","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}
