SPW: Scheduling and Positioning of Web- Services[ ]


With the emergent number of Web services, it has become an urgent task to make operative selection from the large number of functionally-equivalent Web service candidates. It is estimated that there would be large number of web services developed, deployed in the internet in next several years. Earlier approaches proposed that two major properties should be taken into consideration that are functional and non-functional (QoS) when user selects services. There are number of different service provider and we have to effectively select the optimal one from web service candidates. In our approach the requests send by the user are scheduled on the basis of priority scheduling. Then by combining the advantages of network coordinate based approach, collaborative filtering and WSP approach, the response time between user and web services can be accurately predicted. Proposed approach provides selection of services on the basis of user priority.

STUDY OF LEARNING ABILITY OF INTELLIGENT MACHINES IN COMPARISON TO HUMAN[ ]


This is the study of the learning ability of the intelligent machines from the surroundings in contrast to human?s learning ability which is far superior from them(machines). This study includes the study of machines in form of programs (for some), where it is inferred that a machine is not as adaptable to the change as human being, as an instance I?d like to take “crossword puzzler & solver-I” and myself (author). Where it was found that the „adaptability for the change in surroundings? of human being is far more better than the machine. When the puzzler(2) coined “RAPIER?S COUSIN”, and the answer is to be fit in the space of four letters, the solver(2) came up with the answer “EPEE”, same by human. Then puzzler(2) came up with “CEREMONIAL SWORD” ,and the answer is to be fit in the space of five letters, the solve(2) came up with no answer, but the human is.

Secure Mobile Communication via Location Management[ ]


Mobility management is a technique which provides various methods to update location information in response to terminal mobility. Various models are available in mobile communication some are like Okumura and Hata model, Walfisch Ikegami model, 2-ray model, over roof models for location identification. We are using the two ray model for location management. Our work proposes a solution for efficient calling scenario which will not only provide a method to locate a caller that is a solution to locate a caller in callee's mobile unit at user level. Additionally, it leads in optimizing the network usage there by reducing network congestion. Security and privacy issues may arise as the location of the user is revealed. To overcome this situation, we suggest an additional level of verification to activate the application at the service provider’s end.

QSWSP: QoS Based Scheduled Web Service Positioning[ ]


There has been a huge increase in the scale of distributed network service with the rising demand of service-oriented Architecture (SOA), more and more alternative web services offered by different service providers becomes available over the internet to provide equivalent or similar-function for service user. It is estimated that there would be large number of web services developed, deployed in the internet in next several years. Earlier approaches proposed that two major properties should be taken into consideration that are functional and non-functional (QoS) when user selects services. There are number of different service provider and we have to effectively select the optimal one from web service candidates. In our approach the requests send by the user are scheduled on the basis of Earliest Deadline First. Then by combining the advantages of network coordinate based approach, simple regression, clustering approach and WSP approach, the response time between user and web services can be accurately predicted.

Effects of Different Topologies on Network Lifetime in WSN[ ]


Wireless Sensor Network (WSN) is an application of Wireless ad-hoc networks used in everyday lives. The energy efficiency of network is the major challenge facing WSN. This paper investigates the network lifetime of WSN and different network parameters like throughput, packets dropped, delay and jitter on different network topologies. Two WSN networks comprising of 20 nodes and 100 nodes with a PAN coordinator in 100 x 100 square meters terrain size has been implemented in QualNet 6.1 simulator. The result indicates that when the number of nodes is increased, Gradient time synchronized protocol topology gives the best network lifetime. Throughput is also highest for the GTSP topology. But the number of packets dropped is high and so as end to end delay.

Effects of Drifts on Synchronized and Unsynchronized Wireless Sensor Network[ ]


Time synchronization is important for a variety of applications in wireless sensor networks including scheduling communication resources, coordinating sensor wake/sleep cycles, and aligning signals for distributed transmission/reception. However, for data consistency and coordination, accurate time synchronization is required between the nodes of WSN field. In this paper, we compare performance of the synchronized and unsynchronized duration of simulation of network using different parameters such as network lifetime, packet dropped, delay and jitter. To validate our design and analysis, we implement the proposed scheme in QualNet 6.1 simulator having 1000 nodes deployed in a 100m X 100m terrain area. Experimental results shows reduces network lifetime and increases delay and packet dropped in unsynchronized drift network when compared with synchronized drift network.

Enhancement of lifetime using relay nodes in wireless sensor networks[ ]


A major challenge in the wireless sensor network (WSN) is to increase the network lifetime. The area around the sink is known as bottleneck zone. To to enhance the network lifetime, relay nodes may be used to forward the received data. This work decreases the traffic load in bottleneck zone which improves the network lifetime. In this paper transmission power of relay nodes is also varied accordingly. A WSN network comprising of 500 nodes with one PAN coordinator in 100 x100 square meters terrain size has been implemented in QualNet 6.1 simulator. Result shows improved network lifetime and throughtput with reduced average ene-to-end delay, average jitter and packet dropped.

Assertion Based Functional Verification of MBIST Controller Using Coverage Analysis[ ]


For the functional validation of hardware designs, simulation with coverage analysis is still the primary means at RTL description of design. Here coverage analysis shows the way towards the optimal use of resource, validation or verification completeness and untested areas of HDL design. The complete coverage analysis of Memory Built in Self-Test (MBIST) controller using several code and functional coverage metrics is presented. Coverage metrics are used to keep the focus at assertions written to verify the functionality of MBIST controller. Use of assertions and coverage metrics gets rid-off massive test patterns to validate the MBIST controller design more strongly. This paper also presents the implementation of March algorithm based MBIST controller using System Verilog. With the help of assertions written in System Verilog and their coverage analysis, the test cases are reduced from 88 test cases to 25 test cases to achieve the approximately same functional coverage i.e. 97 % is also discussed in the paper.

Application Sharing In Ad Hoc Network (ASIAN)[ ]


Establishing peer-to-peer (P2P) file sharing for mobile ad hoc networks (MANET) requires the construction of a search algorithm for transmitting queries and search results as well as the development of a transfer protocol for downloading files matching a query. In this paper, we present a special-purpose system for searching and file transfer tailored to both the characteristics of MANET and the requirements of peer-to-peer file sharing. Our approach is based on an application layer overlay network. As innovative feature, overlay routes are set up on demand by the search algorithm, closely matching network topology and transparently aggregating redundant transfer paths on a per-file basis. The transfer protocol guarantees low transmission overhead and a high fraction of successful downloads by utilizing overlay routes. In a detailed ns-2 simulation study, we show that both the search algorithm and the transfer protocol outperform off-the-shelf approaches based on a P2P file sharing system for the wireline Internet, TCP and a MANET routing protocol. Advances in portable computing and wireless technologies are opening up exciting possibilities for the future of wireless mobile networking. A mobile ad hoc network consists of mobile platforms which are free to move arbitrarily. Since the nodes are mobile, internode connectivity may change frequently. There is an increasing demand for applications like multiplayer online gaming, where players residing at different locations participate in the same gaming session through their handheld portable devices. Such applications are characterized by a close degree of collaboration, typical of ad hoc network scenarios.

M- Governance, A solution for health analysis and prevention measures against diseases in rural India[ ]


M-Governance (Mobile-Governance) is a solution come to me by a survey of monitoring the health and disease prevention measures of the mass living in rural India. I’m taking an instance of a senior citizen who doesn’t got his telephone bill due to postal mishap and on the verge of terminating his connection of landline, he informed this to BSNL(The facelift of DoT-Department of Telecommunication ), and after that to his surprise he got billing information on his registered mobile number. To his ease of not getting his telephone bill on time, the citizen can rely on his gadget. From this instance I’m sure that this (M-governance) tool can be a boon to the rural society of India, which comprises of 70% of population, if apply effectively. This survey emphasizes on using smart devices intelligently, not mere creating intelligent devices for smart people.
