Clouds are most often serving Developers or Businesses, or Large Enterprises as a new way to host applications. These applications are usually delivered to client PC’s or PC-like smart phones. We consider the case where the clients are highly mobile, very interactive, and very functional, such as in a car. The car is in and of itself a rich, three screen client (Phone-like, Television-like, Computer-like) which can host complicated application scenarios, with some logic in the car, and other logic “in the Cloud”. Additionally, the car can represent a collection of next generation sensors eventing up to the cloud. We explored the resultant needed capabilities of such a cloud, and concluded that a very rich Platform-as-a-Service (PaaS) Cloud Computing platform, far beyond the capabilities of today’s PaaS system, would be required to support such a large collection of mobile devices. We have generated an architecture for this platform from collecting requirements from several Connected Car applications, and are now modeling the results simulating millions of cars on the road per country. The PaaS system emerged with different mechanisms to other PaaS systems in existence.","PeriodicalId":152012,"journal":{"name":"2010 Fifth International Conference on Systems and Networks Communications","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127237084","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}

Nowadays, one of the most promising Broadband Wireless Access (BWA) technologies is Worldwide Interoperability for Microwave Access (WiMAX), characterized by the IEEE 802.16 standard. Efficient data transmission and available bandwidth use optimization are main factors which indicate quality of any communication network. In turn, one of the conditions that determines good channel utilization is the amount of overhead introduced because of the headers of transmitted packets. WiMAX technology is not exempt from this problem, mainly because of its centralized architecture. In this paper, we present an algorithm based on the Earliest Deadline First (EDF) scheduler, which allows to reduce above mentioned overhead, maintaining required Quality of Service (QoS) parameters.","PeriodicalId":152012,"journal":{"name":"2010 Fifth International Conference on Systems and Networks Communications","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124584738","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}

A flight strategy is developed to emulate such a satellite pass as best possible, with the strategy implemented in software on in-flight PC hardware. A full interface between the aircraft avionics and satellite bus system has been developed to enable generation of the required antenna steering commands and to create a satellite bus image to the payload. Successful test results are presented, as obtained from the actual aircraft flight simulator.

The approach is to propose an easy gateway that enables the use of cellular networks based services by wireline users and applications. The idea is to use a mobile terminal or wireless equipment for sharing cellular services, available thanks to its cellular network, to other users that use the wireline Internet. The software application acts as a gateway between the cellular and the wired network; it is responsible for supporting the services provided by the wireless network and make them accessible and usable, in a standard and easy way, by anyone on the wireline network. The gateway software can be integrated easily on any complex architecture since it can interact with any cellular modem. The paper describes an implementation prototype where some examples of services, such as the ability of using messaging services and calls streaming, are experimented.

Classification based on machine learning offers an alternative method to methods based on port or payload based techniques. It is based on statistical features computed from network flows. Several works investigated the efficiency of machine learning techniques and found algorithms suitable for network classification. A classifier based on machine learning is built by learning from a training data set that consists of data from known application traces. In this paper, we evaluate the efficiency of application-layer classification based on C4.5~machine learning algorithm used for classification network flows from different high speed networks, such as 100~Mbit, 1~Gbit and 10~Gbit networks. We find a significant decrease in the classification efficiency when classifier built for one network is used to classify other network. We recommend to build classifier from data collected from all available networks for best results. However, if different networks are not available, good results can be obtained from data traces to the commodity Internet.","PeriodicalId":152012,"journal":{"name":"2010 Fifth International Conference on Systems and Networks Communications","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124095982","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}

It is followed by the presentation of the main features of three UFA signaling protocol alternatives. Finally, the terminal scores of the alternatives are analyzed under different circumstances. The SIP-based alternative shows high performance, and low deployment cost. It is adequate for IMS applications. However by the increase of the demand to support the mobility of legacy internet applications, HIP or MIP-based signaling schemes are more suitable to our criteria.

This paper addresses “high availability”, one of the basic requirements of today systems on the Internet, presenting the main concepts, drawbacks and an automaton for these drawbacks' solution. Based on the two main protocols for high availability (VRRP and CARP), in particular, two problems are addressed, which leads to the environments do not respond to requests for services: split brain and no-brain. These protocols will be fast presented, as well as the study on the basis of the problems mentioned and observed in a production environment.
