Comparative analysis of deduplication techniques for enhancing storage space

Abstract: Data is the most imperative part of any organization for their productive need or to make more profit. Rapid growth data with variations is solemn issue to handle or process. Data is generating at higher rate that data needs to be stored the databases with uniqueness. Deduplication is a technique to abolish the duplicated data from the databases and provides the backup of the data. In data deduplication numerous algorithm are feasible that basically detect a eliminate the redundant data and store unique copy of data contents. Various chunking techniques are used for t backup operations and to perform deduplication of the data. Various chunking techniques like Fixed sized chunking Whole file chunking and Content Defined Chunking are used for the data deduplication. Backup operation is achieved using these chunking techniques. These techniques are compared with each other for getting best suited technique for t backup job. In this paper we have presented performance evaluation of various deduplication techniques. Performan parameters matrix having parameters Deduplication ratio, Deduplication time, Hashing time, Chunking time a Throughput. The analysis result provides some guidelines to adopt the best deduplication techniques to clear away fro clone data. After comparing these chunking techniques based on different parameters it is concluded that variable size chunking algorithms are the best suited deduplication techniques for the backup operation.

QOS Improvement in MANET Routing by Route Optimization through Convergence of Mobile Agent

Abstract: A, Mobile ad-hoc network (MANET) is collection of mobile devices that desire to communicate in the lack of any fixed infrastructure so, in this environment every mobile nodes works as a router in itself. In this type of wireless network, any node can leave or join network at any movement. Besides it this type of networks have some other challenging characteristics as regularly changing topology, high mobility, narrow bandwidth. Conventional routing protocols focused on finding shortest path rather than Quality of Service path. Link breakage is the main reason of high mobility as well as lack of energy of wireless nodes. In the lack of resources, traffic density leads to congestion. So, the performance of routing protocol degrades in this type of networks. But it is not so easy task to take multiple QoS parameters for finding optimal route. Mobile software agent technology with unique features like mobility, autonomous, intelligent and adaptability can solve this problem. This research paper focuses on designing routing model using mobile agent paradigm. The proposed model attempts to find more optimal path by considering multiple QoS parameters like stability, delay, congestion and energy of the node. Simulation is done using Matlab simulator & the simulation output shows that our proposed model is more reliable than traditional hop by hop AODV for finding the route from source node to destination node.

A Microstrip Wideband Balun Bandpass Filter with H-shape Resonators

Abstract: A novel approach to design a Microstrip wide band bandpass filter (BPF) with H-shaped resonators is exhibited in this letter. By using the standing-wave property of voltage conveyance along an open circuited half-wavelength (λ/2) Microstrip transmission line, the out-of-phase signs can be acquired at two yield ports of a balun. In the mean time, appropriate coupling topologies between the open-circuited λ/2 Microstrip transmission line and the multi-mode resonators are designated to accomplish a balun BPF with both attributes of parity balance performance and wideband filtering properties. To validate proposed work, a balun BPF working at 1 GHz with a 3 dB FBW of 30% is simulated and measured. Both the simulation and measurement results of the composed balun BPF with H-shaped resonators are given a decent assertion. Results demonstrate that this balun BPF displays not just a high selectivity filtering execution with two regular transmission zeros (Tzs) of S21 and S31 outside the passbands, additionally a decent adjust execution with 0.5 dB amplitude imbalance and 5° phase imbalance.
