A common WLAN application is Wi-Fi technology, where it is easy to find in public areas and has a great interest of internet access users, particularly those who use mobile devices (nodes) such as notebooks and mobile phones. The phenomenon has impact on the energy consumption in Wi-Fi networks. Nowadays, the consumption, management and energy efficiency of indoor wireless networks are important issues. Therefore, this paper analyses the energy efficiency for Wi-Fi 802.11b multi-hop networks. The Wifi 802.11b multi-hop network is simulated using Network Simulator 3 (NS-3), in which the network consists of a line sequence of 5 wireless nodes that are a source, three relays and a destination. In the simulation, several energy parameters are considered such as the number of nodes, grid spacing, packet size and data rate. Moreover, several important energy efficiency factors are analyzed including energy consumption, effective energy utilization, bit energy, throughput and energy efficiency. The simulation results show that the number of the packet size and throughput have impact on energy consumption and energy efficiency in the network. While effective energy utilization decreases as the throughput of the network increases. Therefore, the Wi-Fi 802.11b multi-hop network can be an alternative green communication method which has a higher energy efficiency.","PeriodicalId":378333,"journal":{"name":"2013 IEEE International Conference on Communication, Networks and Satellite (COMNETSAT)","volume":"20 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":"127677661","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}

Precoding is a generalization of beamforming to support multi-layer transmission in multi-antenna wireless communications. Beamforming is a signal processing technique used in sensor arrays for directional signal transmission or reception. In conventional single-layer beamforming, the same signal is emitted from each of the transmit antennas with appropriate weighting such that the signal power is maximized at the receiver output. When the receiver has multiple antennas, single-layer beamforming cannot simultaneously maximize the signal level at all of the receive antennas. Thus, in order to maximize throughput in a receiving antenna system, integrated precoding in multi-layer beamforming is required. LTE linear precoding system for the transmitter side is built in this research. The precoding system will be built in VHDL code and will be implemented on FPGA. In this research, the precoding sistem consists of 64-QAM Mapper as input system, and will be connected to OFDM (IFFT) block. The precoding is built based on Transmission Mode (TM) 6 of LTE release 9 and will be using 3GPP codebook standard as the precoding matrix for TM 6 for 2x2 MIMO. The research shows that by the used of linear precoding system in transmission, it decreases the complexion of detection system in precoding block on the receiver side. The implementation process shows that the research is implementable on hardware and will use 62% occupied slices, 11% slice register, and 27% of bounded IOBs resources of FPGA. with 2021 clock in total process, 121 clock in delay process and 1900 clocks to produce one OFDM symbol. The bitrate of the system is 161.68 Mbps.","PeriodicalId":378333,"journal":{"name":"2013 IEEE International Conference on Communication, Networks and Satellite (COMNETSAT)","volume":"19 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":"123022838","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}

The issue of identifying appropriate cluster heads (CHs), forming energy efficient clusters and transmitting data packets to base station (BS) by direct or multi hop are important problems. This paper presents two approaches for two different scenarios. First, Energy Efficient Hybrid Clustering Scheme (EEHCS) is for direct hop communication to the BS when BS is situated within the sensing region and second, Energy Efficient Hybrid Multi-hop Clustering Scheme (EEHMCS) is for multi-hop communication to the BS using other CHs when BS is situated far away from the deployment region. In both the approaches, BS selects energy efficient CHs depending on remaining energy and number of member nodes by a centralized CH election method and broadcasts the selected CH message to all the nodes to reduce the control messages overhead required for distributed clustering approach. Simulation results show that EEHCS prolong the network lifetime upto 27:63% over LEACH-C, whereas, EEHMCS performs 2 times better than LEACH-C for first node die in certain network setting.","PeriodicalId":378333,"journal":{"name":"2013 IEEE International Conference on Communication, Networks and Satellite (COMNETSAT)","volume":"37 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":"114591855","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 reduce interference among these users, CRN imposes a maximum limit on total number of users that can be admitted in CRN. The overall user capacity is further increased by implementing VoIP based 2-tier CRN that allows another group of secondary users to transmit by exploiting silence suppression characteristics of secondary users involved in VoIP communication. The practical issues involved in designing VoIP based 2-tier CRN are discussed in this paper as it provides novel implementation design models for 2-tier CRN. Two algorithms based on message passing policy are proposed for deploying VoIP based 2-tier CRN with the aim of increasing system capacity while reducing interference among users. Detailed mathematical formulation establishes superiority of 2-tier CRN over basic CRN with 77% improvement in spectrum utilization. Performance analysis in simulation model validates the inferences drawn from mathematical model.","PeriodicalId":378333,"journal":{"name":"2013 IEEE International Conference on Communication, Networks and Satellite (COMNETSAT)","volume":"115 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":"133148043","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}
