The present mobile cellular communication networks normally often suffer from poor penetration and reception in certain areas, like indoor and apartments in turn decreasing quality of service. The main backbone of Long Term Evolution Advanced (LTE)- mobile network is internet. In order to reduced the traffic and enhance data rates, femtocell can be used to improve wireless coverage over a small area, especially in indoor and urban environment. Femtocell is a small cellular base station that connects to a broadband Internet connection. The major technical challenges of femtocells are cross-tier, Intra-tier and user equipment interference, quality of service, handover operation and spectral accuracy. The predominate issue is cross-tier interference constituting macro cell and femtocell networks constitutes the greater portion of interference in terms of adjacent channel interference. In this paper, Interference levels in reception of heterogeneous LTE Network by using two different path loss models are investigated. Signal to interference ratio and the throughput are estimated The trade-off between selections of Femto or Macro BS link by the User Equipment (UE) is examined by considering number of walls and penetration losses of Computer Block (7 floors, 10 walls), KL University, Vaddeswaram, Guntur, India. It is found that that model-2 is better in Interference mitigation and path loss estimation compared to model-1.","PeriodicalId":149158,"journal":{"name":"2014 Eleventh International Conference on Wireless and Optical Communications Networks (WOCN)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124622903","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}

LTE is a way for cellular communications to operate at that high data rate. Routing is an important operation performed to route the data packets from the source node to destination node in any network. Hence there is a need for a protocol/algorithm to determine the best way to transfer the data. Routing protocols determine the best route to transfer data from one node to another. In this paper, a comparative study of the routing protocols for the application layer of LTE network is done. The protocols analyzed are Optimized Link State Routing (OLSR) and Routing Information Protocol (RIP). A study and comparison of the parameters are done based on the simulation results. The different performance metrics analyzed are Packet delivery ratio, Throughput, Average end-to-end delay and Jitter. The simulation results show that the best routing protocol w.r.t all the parameters analyzed is RIP.","PeriodicalId":149158,"journal":{"name":"2014 Eleventh International Conference on Wireless and Optical Communications Networks (WOCN)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122009526","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}

Every time we lower our utility bills, we put more money back in our bank account and lower energy bills also means less energy consumed, which means less harmful emissions released into our environment. To make our homes more energy efficient, one of the least expensive and most effective changes that we can make is replacing the light bulbs. Hence this project proposes an intelligent house hold LED lighting system to make the house energy efficient and user satisfied. The proposed system utilizes multi sensors and wireless communication technology in order to control a LED light according to user's state and surroundings. An ARM 7 based embedded system design with day light and PIR sensors will be attempted to control the lighting and its intensity in a household environment. The wireless communication technology uses zigbee and RS-485 protocol for serial communication. The proposed system after implementation will be verified for its performance against a conventional system and the percentage of energy saving will be calculated.","PeriodicalId":149158,"journal":{"name":"2014 Eleventh International Conference on Wireless and Optical Communications Networks (WOCN)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126395449","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}

One such antenna which satisfies these requirements is the Vivaldi antenna. Conventional exponentially tapered slot Vivaldi antenna offers only a small gain at lower microwave frequencies. This paper presents the design of the complex flare geometry of a Vivaldi like antenna, using fourier series approach. In general, the radiating flare of a Vivaldi antenna is a closed contour and any complex closed structure can be represented using finite fourier series. Fourier coefficients and hence the antenna shape is selected so as to achieve the objective of maximum gain and minimum reflection coefficient (S11). Designed antenna structure using FR4_epoxy dielectric (εr=4.4, h=4.5 mm, tanδ=0.002) as substrate has a dimension of 79×126 mm and it can be operated over a band of spectrum from 2.1 to 9.2 GHz. At a frequency of 2.6 GHz it offers a peak gain of 6.1226 dB. Simulations were performed in high frequency structure simulator (HFSS) and antenna parameters like return loss (S11), radiation patterns, gain and directivity are studied. Simulation results and measurements made from prototype agrees well, which verifies the proposed design concepts.","PeriodicalId":149158,"journal":{"name":"2014 Eleventh International Conference on Wireless and Optical Communications Networks (WOCN)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115636882","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}
