MANET has advantage of operating without fixed infrastructure and also it can tolerate many changes in the network topology. The MANET uses different routing protocols for End to End Packet delivery. This paper is subjected to the Reactive r outing protocols on the basis of identical environm ent conditions and evaluates their relative performance with respe ct to the performance metric Packet delivery ratio, overhead & throughput. In this Reactive routing protocols can spectacularly reduce routing overhead because they do not need to search for and maintain the routes on which there i s no data traffic. This property is very invoking i n the limited resource. Achieve a good efficient network life and reliability need a variation on the notion of mult icasting. Geocasting is useful for sending messages to nodes in a specified geographical region. This r...

Though various transforms are used in the field of image compression. like EZW, SPIHT and EBCOT. In this research, Walsh wavelet transform are used to perform the transform of a test image. Experimental results show that the image quality is almost same when CRF is in small amount. We can calculate the size of compressed image and decompressed image with how much time it takes in compression as well as decompression.

The distortion and degradation of image suffered the process of pattern matching and quality of image. Wavelet is very important transform function play a role in image enhancement and image de-noising. The concept of wavelet used as soft thresholding and hard thresholding. A processing of data through wavelet is very efficient in process of neural network. In this paper we discuss the proposed algorithm for image enhancement based on self organized map network and wavelet transform. Basically self organized map network is unsupervised training mechanisms of pattern, due to this reason the processing of network is very fast in compression of another artificial neural network method. And the combination of wavelet and self organized map network have great advantage over conventional method such as histogram equalization and multi-point histogram equalization and another conventional technique of image enhancement.

The effectiveness of a digital watermarking technique is indicated by the robustness of embedded watermarks against various attacks. A new method for watermarking is suggested is feature based watermarking. For getting robust watermark, the watermark should be embedded in silent part of the data and for these significant features of data is used. In this paper few methods of feature extraction as Harris Laplacian, Laplacian-of-Gaussian, Susan, Gilles are applied for feature extraction. Robust Non overlapping regions against different attacks are selected for watermarking. Comparison for robust feature selection is done against different feature extraction methods. In next stage those regions are pruned to get minimal primary feature region set using pruning algorithm and watermark is embedded in selected regions and then again results of extracted watermark is compared against different feature selection methods for robustness.

As the MANET is infrastructure less, it is having dynamic nature of random network topology. Due to movement of nodes, the link between nodes breaks. The network needs to find a new route from source to destination. In order to find a route network initiate a route discovery procedure by broadcasting route request packets. The frequent invention of route increases the routing load and end to end delay. The existing ad hoc routing protocols based on hop count metric which doesn't take in its consideration the stability of the link. The requirement is to discover a routing protocol that considers link stability during discovery of route, so resulting route is more stable than existing routing protocol. In this paper we compare performance of AODV and Path loss sensitive AODV which finds a stable path using received signal strength.

Cloud computing, one of the emerging techniques to lease computing resources on demand, makes use of remote data storage where data owner does not possess direct control over her data. To protect privacy of users' data and to enable user to verify integrity of the data stored on remote location, modern cryptographic techniques are used. Cryptographic techniques impose computational and communication overhead which in turn affect the performance of the overall operation. In this research article, we analyze two broad categories of cryptography viz. symmetric key encryption and encoding. We analyze various algorithms and compare them on the basis of security and performance perspectives. We further make recommendations for Cloud users to protect & verify their sensitive data using one of these cryptographic techniques..

The computing paradigm that comes with cloud computing has incurred great concerns on the security of data, especially the integrity and confidentiality of data, as cloud service providers may have complete control on the computing infrastructure that underpins the services. In this paper we want to generalize the formulation of data mining techniques with cloud computing environment. In data mining we want to find useful patterns with different methodology. The main issue with data mining techniques is that the space required for the item set and there operations are very huge. If we combine data mining techniques with cloud computing environment, then we can rent the space from the cloud providers on demand. This solution can solve the problem of huge space and we can apply data mining techniques without taking any consideration of space. This paper basically survey and analyze the utility for solving the above situation.

So, Fog elimination is extremely preferred in both estimation picture making and computer vision applications. Proposed technique uses a Dark Channel Prior with contrast stretching to remove fog and improve the contrast of fog free image, respectively. Using Dark Channel Prior method one can directly take away the thickness of the haze and recover a high quality haze free image. Contrast Stretching is applied in the resulted image of dark channel prior method to improve the contrast of image. The noise that affect foggy image can also be ease by using the median low pass filter. By using this technique the visual quality and color of the foggy image can be correct effectively. Experiments are conducted on PSNR and RMSE parameters. Experimental Result shows that proposed method contains least average RMSE values and Higher PSNR values among other methods.
