The basic Release-8 of LTE and the subsequent modifications do not specify any scheduling algorithm making the task of improving user satisfaction more difficult. In our work, we proposed a two-level scheduler with game theoretic application that distributes resources among classes with fairness and then implements a delay based scheduler to satisfy the strict levels of delay budget requirements of LTE classes. A coalition is formed between different class flows by use of bargaining cooperative game that allows for distribution of physical resource blocks in a fair manner via Shapely function. The delay based scheduler checks and compares users packet delay in a service class to make scheduling decisions in the downlink utilizing recent user reported channel conditions. Simulation results carried out with key performance matrices like packet loss ratio, throughput, fairness index and system delay prove the effectiveness of the proposed approach as compared to Exponential Rule, Proportional Fair and M-LWDF algorithms and its usefulness for supporting both real time and non-real time traffic is verified.","PeriodicalId":101923,"journal":{"name":"2011 Frontiers of Information Technology","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116171121","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}

We have proposed a simple yet efficient algorithm to calculate the number of vehicles at various signals on a road to efficiently manage the traffic by controlling traffic signals to avoid congestion and traffic jam. The proposed system works by detection of vehicles in video frames acquired by cameras installed on roads and then perform accurate counting of vehicles at the same time. Dynamic background subtraction technique and morphological operations for vehicle detection have been used to achieve better detection efficiency. In order to attain accurate vehicle count in least possible time, we have used Region of Interest based method for vehicle calculation. The proposed framework is designed and implemented in several simulation test cases. It is expected that this work will provide an insight into the design and development of traffic signaling based system and also serves as a basis for practical implementation of a computer vision technology in real-time environment. Furthermore, this work also contributes to new design schemes to increase traffic signaling system's intelligence.","PeriodicalId":101923,"journal":{"name":"2011 Frontiers of Information Technology","volume":"164 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125171482","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}
