In the case of internet-access, fixed broadband connections reach currently higher connections speeds than mobile connections. Due to new technologies as LTE Advanced and 5G, mobile accesses get a bandwidth boost and reach a stronger position in terms of broadband speed. This paper discusses mobile radio technologies' influence on broadband markets in the world and especially in Germany. We will answer the question: Will mobile infrastructures dominate broadband markets in terms of market share, access speed, distribution and number of subscribers? First we will give an overview of the current mobile and fixed broadband developments in the world and particularly in Germany, focusing on the number of subscribers, data traffic and revenues. In the second part of the paper, we discuss the field of competition and in which fields mobile and fixed infrastructures are in a direct competition. Furthermore, we will present the effect of the different technical characteristics of the mobile and fixed technologies and their impact on the broadband markets. Finally, we try to figure out how broadband technologies will develop in the short and long run.","PeriodicalId":389513,"journal":{"name":"2015 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128750011","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}

This new access type allows to optimize the spectrum sensing time with throughput improvement. Our proposed access type is based on a merger of these two modes depending on the number of secondary users (SU) in the Underlay Mode and on the access probabilities for these two modes. The number of all users in the Underlay access mode should not exceed a certain number of users. When a new SU arrives and if the number of SUs in Underlay mode is already equal to the predifined max number, the SU decides to switch to the Overlay mode to access the canal using this method. The SU states will be modeled with a Markov chain, the aim of this work is attempting to show that this new method allows to increase the throughput of the SU with energy optimization. The exact outage probability of secondary system is also derived for this model. Simulation results show that the performance, especiallay the throughput can be significantly increased by the proposed hybrid system.","PeriodicalId":389513,"journal":{"name":"2015 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127072931","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}

Indeed it's well known that the Medium Access Control protocols are designed based on the assumption that all mobile users act selfishly and follow a personal objective, such behavior may decrease the performance of the majority of users, hence causing fairness issue and decreasing the global energy consumption significantly. In this paper we propose a reward mechanism in a non-cooperative game framework. We assume that the base station promises the user a reward which can be a number of amounts of credit that the users use to transmit their own packets. The reward is given only to a user that transmits its packet successfully. First, we analyze the implementation of our mechanism on the equilibrium and show that as the arrival rate increases, the behavior of users become more and more aggressive resulting in a global deterioration of the expected reward the base station pays. Second and in order to achieve an efficient outcome despite the selfish behavior of users, we propose an incentive mechanism when each failure transmission of a packet incurs a certain number of costs. The cost could in fact be expressed in terms of the energy consumption when attempting to access the wireless channel. Under the proposed scheme aggressive behavior is discouraged since each retransmission translates into the depletion of the energy stored in the battery. Via the price of anarchy we show that the global performance of the system is improved considerably compared to the original game in particular at high loads.","PeriodicalId":389513,"journal":{"name":"2015 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127700001","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 order to increase the system performance up to the Shannon limit a suitable resource management (RRM) exploiting this key features is a needed. Packet scheduling mechanisms particularly play a fundamental role to guarantee a better RRM, because they are responsible for choosing, with a fine time how to distribute the satellite resources among different terrestrial stations, taking into account channel condition and the quality-of-service requirements. This goal should be accomplish by providing, at the same time, an optimal trade-off between spectral efficiency, given the limited resources on satellite systems, while granting the requirements for quality-of-service. In this context, this paper provides an overview on the key issues that arise with the use of ACM technology and GSE encapsulation in the design of a scheduler to allocate satellite resources. Moreover, a survey on the most recent scheduling techniques is reported, including a comparison between different approaches presented in literature.","PeriodicalId":389513,"journal":{"name":"2015 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114477203","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}
