In this paper most popular filtering techniques have taken for comparison, that are Non Local Mean method, Particle filtering and Markov random fields. The Original NL Mean method replaces a noisy pixel by the weighted average of pixels with related surrounding neighbourhoods. In order to accelerate the algorithm; the filters are used to eliminate unrelated neighborhoods from the weighted average. The particle filtering technique will give statistical behavior of the image. The most appropriate window or neighborhood shape and size to estimate the image intensity in a given position. One attempt is to do perform filtering by selecting the neighboring pixels in a random fashion but without taking image structure into account. MRFs can be used as parametric models for the probability distribution of intensity levels in an image. The resulting framework explores optimally spatial dependencies between image content towards variable bandwidth image reconstruction. The results of techniques Non Local Mean method, Particle Filters and Markov random fields are compared by using two parameters such as PSNR and MSE values for the reconstructed images.Markov Random Fields method provides a better result when compare to Nonlocal mean method and Particle Filter.","PeriodicalId":364589,"journal":{"name":"2012 Third International Conference on Computing, Communication and Networking Technologies (ICCCNT'12)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126602740","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, we discuss the maximum physiological parameters that an oximeter installed in the steering wheel of an automobile can measure. A pulse oximeter which is normally used for measuring blood oxygen saturation is exposed to magnetic fields to obtain the blood viscosity, which is an essential parameter to keep the body haemodynamically stable. RGB color band analysis is made on the oximeter output in order to obtain the electro-cardiac signals from the Green band. Measurement of respiration rate is done by amplitude and frequency modulation of the light signal [1]. In case of cardiac arrest, the vehicle is changed to cruise control mode and the measured parameters will be sent to any nearby hospitals for assistance using GPS. The RFID tags are also used to communicate to the nearby vehicles to alert other drivers for emergency assistance. Each and every vehicle is equipped with automatic external defibrillator (AED) with detailed instructions on how to operate the AED, in order to defibrillate a person in cardiac arrest.","PeriodicalId":364589,"journal":{"name":"2012 Third International Conference on Computing, Communication and Networking Technologies (ICCCNT'12)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129797400","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 large subset of sensor network applications requires security, especially if the sensor network protects or monitors critical infrastructures. Unfortunately, the simplicity and low-cost of the sensors eases cloning and create a sibling of compromised nodes by attackers. These ID based assaults are the entry point to a large span of insidious attacks. In such circumstances, an adversary uses the credentials of a compromised node to surreptitiously introduce anomalies into the network. These infected nodes are then used to launch a variety of attacks that subvert the goal of the sensor application, and the operation of the underlying protocols. The detection of such attacks in a wireless sensor network is therefore a fundamental problem. Intension of this work is insinuate a new environs based beamforming approach (ESMS) to detect both clone and Sybil attack with the same strategy.","PeriodicalId":364589,"journal":{"name":"2012 Third International Conference on Computing, Communication and Networking Technologies (ICCCNT'12)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116868154","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 further improvement of data transmission with the limited bandwidth is achieved by multiple-input multiple-output (MIMO) structure. The MC-CDMA system is subject to limiting factors such as multiple-access Interference (MAI) and inters carrier interference (ICI) and these interferences diminish attainable throughput performance. The transmission strategy to avoid the interference noise is by its power allocation to each user. The Game theory is an effective tool for examining power control problem in the MCCDMA technology with imperfect channel state information. The water filling algorithm in game theory is used to allocate proper power for every sub-channel in order to improve channel capacity. In this paper iterative water filling power control algorithm to allocate power for each user is adopted in MCCDMA-MIMO system. The water filling algorithm distributes power among all users with the help of SINR that is received by the transmitter instead of getting full channel state information. The capacity enhancement in MCCDMA is evaluated with and without water filling algorithm and further performance improvements are analyzed by transmitting through MIMO system.","PeriodicalId":364589,"journal":{"name":"2012 Third International Conference on Computing, Communication and Networking Technologies (ICCCNT'12)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125128989","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}
