In this paper we investigate appreciably enhancement of the gain & radiation pattern of a low profile micro strip patch antenna by placing a metamaterial slab above it (as a super strate) using CST MWS simulator. This paper proposes a metamaterial super strate surface as a reflective surface for micro strip patch antenna (MPA). The MTM structure was a combination of the triangular SRR (TSRR) and the wire strip (WS) to obtain negative values of permittivity & permeability. The gain of the MPA with MRS is around 5 dB higher than that of conventional MPA on FR4 substrate. These improvements were due to negative refraction characteristics of LHM structure that converts into super-lens, when placed in front of the antenna. The small spacing between MRS and the patch surface was another merit in the present design, which was as low as ?/10 as it results in low profile antenna design, that will suits in modern wireless communication system.","PeriodicalId":292190,"journal":{"name":"2011 International Conference on Computational Intelligence and Communication Networks","volume":"421 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132834019","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}

Adaptivity of Arod Routing Protocol in Sparse and Dense Ad-Hoc Networks 稀疏和密集Ad-Hoc网络中Arod路由协议的自适应研究

{"title":"Adaptivity of Arod Routing Protocol in Sparse and Dense Ad-Hoc Networks","authors":"Kiran Modani, A. Katariya","doi":"10.1109/CICN.2011.21","DOIUrl":"https://doi.org/10.1109/CICN.2011.21","url":null,"abstract":"The dynamics of an ad hoc network has became vital factor for protocol design because mobility of nodes leads to unstable routing, and consequently flows encounter fluctuations in resource availability on various paths during the lifetime of a session. This has become serious, especially for those protocols based on single-path reservation, as frequent reservation and restoration of reservation-based flows increase the instability of connections. Advances in wireless research are focusing more and more on the adaptation capability of routing protocols. These protocols are interrelated to each other among various performance measures such as those related to topological changes (link breakages, node mobility, etc.) and quality of service (QoS) parameters. Sometimes, dynamic ad hoc networks resemble a dense ad hoc network. At other times, they resemble sparse network where nodes are located far away from each other. Many real networks follow the structure of dynamic ad hoc networks. Military networks, wildlife tracking sensor networks, and vehicle networks are some of these examples. In dynamic ad hoc networks, conventional routing schemes fail when the network characteristics do not fall into their applicable scenarios. Previous research has proposed a variety of routing schemes for each specific network scenario. For instance, distributed routing tables are built for efficient multi-hop, single copy routing in static and dense networks. Mobility assisted multi-copy routings are proposed in sparse networks where contemporary paths might not exist. After having review on these protocol and using some specific characteristic from these protocol we have designed a new routing algorithm that can work well in dense as well as sparse network. With the advantages of the existing schemes in mind, we introduce a new routing scheme, Adaptive Routing in Dynamic ad hoc networks (AROD), which is a seamless integration of several existing schemes.","PeriodicalId":292190,"journal":{"name":"2011 International Conference on Computational Intelligence and Communication Networks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133576092","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}

A neural network is a processing device, whose design was inspired by the design and functioning of human brain and their components. The proposed solutions focus on applying Bidirectional Associative Memory method model for pattern recognition. The primary function of which is to retrieve in a pattern stored in memory, when an incomplete or noisy version of that pattern is presented. An associative memory is a storehouse of associated patterns that are encoded in some form. In auto-association, an input pattern is associated with itself and the states of input and output units coincide. When the storehouse is incited with a given distorted or partial pattern, the associated pattern pair stored in its perfect form is recalled. Pattern recognition techniques are associated a symbolic identity with the image of the pattern. This problem of replication of patterns by machines (computers) involves the machine printed patterns. There is no idle memory containing data and programmed, but each neuron is programmed and continuously active.","PeriodicalId":292190,"journal":{"name":"2011 International Conference on Computational Intelligence and Communication Networks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128557785","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 this paper a Fuzzy Inference System (FIS) is proposed, which learns gestures with segmentation and motion primitives, recognize gestures with created rule-based system in learning phase, and generate interactive gesture for HOAP-2 robot using real-world human interaction patterns. We also have a pre-processing element during gesture learning, which helps in better fuzzy rule generation and recognition with motion recognizer.
