MIMO is a widely researched topic, and understanding of MIMO concepts have an interaction with other essential enhancement mechanisms in the system including link adaptation, resource scheduling, inter stream interference, rank of the channel, etc. This paper mainly aims to target the MIMO mode adaptation strategies in LTE systems by considering the rank and other key parameters like antenna correlation, doppler frequency, bit rate, throughput, etc. 3GPP LTE rel-8 has adopted seven MIMO modes and variable modulation and coding schemes (MCS) to effectively utilize the available resources for maximizing the throughput of the system. In this paper, new techniques for obtaining appropriate rank and a new MIMO mode switching algorithm to maximize data rate of the user equipment (UE) for a given channel consider at the receiver with reasonable complexity, and there by improving the average system throughput are proposed. The paper considers only four MIMO modes namely transmit diversity, open loop spatial multiplexing (OLSM), closed loop spatial multiplexing (CLSM) and beam-forming with different modulation levels. MIMO mode switching is done based on throughput value between open loop modes namely transmit diversity and OLSM for high mobility UE in the presence of co channel interference (CCI). Similarly, mode switching is done between closed loop modes namely CLSM and beam-forming for pedestrian UE in the presence of CCI. Simulation results are provided to illustrate the performance benefits of the proposed algorithm. The simulation results reveal that these new techniques improves the system throughput significantly.","PeriodicalId":286834,"journal":{"name":"2013 IEEE International Conference on Advanced Networks and Telecommunications Systems (ANTS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127204991","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}

Cognitive Radio Network (CRN) allows opportunistic uses of spectrum holes by enabling the coexistence of licensed (primary) users and unlicensed (secondary) users. Data dissemination in a CRN is very useful to propagate non-urgent messages in order to limit cost and complexity of the network. MAC protocols in existing legacy wireless networks do not support the coexistence of licensed and secondary users. This limits the productive utilization of spectrum holes by secondary users. In this paper, we propose a distributed TDMA based MAC protocol for data dissemination in multi-hop ad-hoc CRNs. Our protocol aims at not only ensuring highest message reachability but also avoiding collision among secondary users. It classifies the set of available channels based on both primary radio unoccupancy and number of cognitive radio neighbours having the channel in their available channel set. The secondary users prepare a TDMA schedule using a distributed approach. Secondary users select the best channel from the available channel set using a channel selection strategy. This increases data dissemination reliability in multi-hop ad-hoc CRNs. Simulation results show the efficacy of proposed method.","PeriodicalId":286834,"journal":{"name":"2013 IEEE International Conference on Advanced Networks and Telecommunications Systems (ANTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131119798","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}

Current protocols such as TCP/IP were not originally designed with mobility as a key consideration, and therefore underperform under challenging mobile and wireless conditions. MobilityFirst, a clean slate architecture proposal, embraces several key concepts centered around secure identifiers that inherently support mobility and trustworthiness as key requirements of the network architecture. This includes a hop-by-hop segmented data transport that allows late and dynamic rebinding of endpoint addresses to support mobility. While this provides critical gains in wireless segments, some overheads are incurred even in stable segments such as in the core. Bypassing layer 3 decisions in these cases, with lower layer cut through forwarding, can improve said gains. In this work, we introduce a general bypass capability within the MobilityFirst architecture that could provide both better performance and enable both individual and aggregate flow-level traffic control. Furthermore, we present a detailed OpenFlow-based design to bypass layer 3 routing in MobilityFirst, using layer 2 VLAN tagging. Finally, we present a prototype that shows that it is possible to use OpenFlow to create the bypass.","PeriodicalId":286834,"journal":{"name":"2013 IEEE International Conference on Advanced Networks and Telecommunications Systems (ANTS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114402926","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}
