The performance of our system is analyzed in a synchronous network using multilevel periodic codes (ML-PC) with a conventional receiver model and the results are compared with those for different receivers. Two solutions to improve the performance are proposed: the parallel interference cancellation receiver (PIC) and the successive interference cancellation receiver (SIC) simulated in the ideal case.","PeriodicalId":334187,"journal":{"name":"High Capacity Optical Networks and Emerging/Enabling Technologies","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116760437","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 objective, however, should be realized by considering an optimal trade-off between system performance and fairness among the users. This work proposes an adaptive packet scheduling mechanism which provides higher spectral efficiency during the times of high system load and a better fairness when enough radio resources are available. The proposed scheme dynamically switches between the well-known Proportional Fair and Blind Equal Throughput scheduling schemes based on the congestion level at the radio interface. Moreover, this work also provides a sophisticated mechanism to estimate the radio interface congestion level to assist the operations of the proposed Adaptive Fair scheduling scheme. The proof of concept is provided with the help of simulation results where the performance of the proposed scheme is evaluated at different radio interface congestion levels.","PeriodicalId":334187,"journal":{"name":"High Capacity Optical Networks and Emerging/Enabling Technologies","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133265664","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}

Furthermore, in such emerging networks, the spatial reuse of resources is permissible and the transmission range can be decreased, then the probability of connectivity is high. In this work, we propose an analytical model for mobile user connectivity probability in Femto-Macro cellular networks. On the other hand, we study the capability of femtocell networks to serve macro users (MUEs) at the boundary of macrocell i.e., no coverage or poor signal as well as to serve the users fully inside the femtocell i.e., reduce the communication load of macrocell. Numerical results demonstrate the efficiency of computing the connectivity probability in Femto-Macro cellular networks.","PeriodicalId":334187,"journal":{"name":"High Capacity Optical Networks and Emerging/Enabling Technologies","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131204862","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 relies on loss or delay measures to infer the existence of congestion (or lack thereof), and reacts by increasing/decreasing a flow transmission rate. Without an accurate estimate of the available bandwidth on the communication channel, TCP is either too aggressive leading to more congestion, or too conservative leading to low channel utilization. Recent advances in bandwidth estimation tools can help TCP achieve better channel efficiency while maintaining fairness among competing flows. In this paper, we propose a rate-based congestion control algorithm that relies on a bandwidth estimation tool, Forecaster, and investigate its performance. Experimental results reveal its superiority to existing algorithms in efficiently using the available bandwidth and in its resilience to lossy channels, making the algorithm suitable for common HTTP short flows and for communication over network paths with wireless hops.","PeriodicalId":334187,"journal":{"name":"High Capacity Optical Networks and Emerging/Enabling Technologies","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128340853","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}

There have been several proposals for optimized design of MG-ONs as power consumption in the Internet backbone has recently become an important concern. Although recent research has shown that multi-granular switching concept can guarantee energy savings when compared to the traditional traffic grooming, MG-ON design still calls for legitimate and self-contained design specifications. In this paper, we revisit the Routing and MultiGranular Path Assignment (RMGPA) problem by having the objective of minimized power consumption. Heuristic solutions of RMGPA problem show that crucial power and cost savings can be achieved with the proper selection of the wavelength capacity, waveband size and number of wavebands per fiber with a certain fiber capacity.","PeriodicalId":334187,"journal":{"name":"High Capacity Optical Networks and Emerging/Enabling Technologies","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116579191","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}

Each vehicle is assumed to be equipped with a Global Positioning System (GPS) device that provides with vehicle's current location, a real-time clock and a wireless communication device such as a two-way radio that allows it to communicate with vehicles nearby.
