Abstract - Energy conservation of sensor nodes for increasing the network life is the most crucial design goal while developing efficient routing protocol for wireless sensor networks. Recent technological advances help in the development of wide variety of sensor nodes. Heterogeneity takes the advantage of different types of sensor nodes and improves the energy efficiency and network life. Generally sensors are deployed randomly and densely in a sensing region so short distance multihop communication reduces the long distance transmission in the sensor network. In this research paper MMEP (multihop energy efficient protocol for heterogeneous sensor network) is proposed. The proposed protocol combines the idea of clustering and multihop communication. Heterogeneity is created in the network by using some nodes of high energy. Low energy nodes use a residual energy based scheme to become a cluster head. High energy nodes act as the relay nodes for low energy cluster head when they are not performing the duty of a cluster head to save their energy further. Protocol also suggests a sleep state for nodes in the cluster formation process for saving energy and increasing the life of sensor network. Simulation result shows that the proposed scheme is better than other two level heterogeneous sensor network protocol like SEP in energy efficiency and network life.

Abstract - In this study, we are discussing our experiences and challenges we faced during the development of an Auto-configuration Server (ACS) for TR-069 protocol. During the development we studied many open-source products regarding ACS. We learned and analyzed them and used some of code in our project. During study we found that those products are not developed maturely and also not properly documented, so we need to go through the project by understanding the source code to find out the product architecture and process flow. This paper also discusses how we faced those challenges and solve the by using different software engineering techniques. We studied architecture of one the best product among the list and how we change it into real time product for industry. We are sharing those experiences that are helpful and provide some guidance for others who are planning to develop such kind of system.

Abstract - User Interface is an important component of every computing system. This is particularly true in Internet Banking, where the users are customers, who access the banking services online, from different locations of the world. These customers when dissatisfied with the banking services could take drastic actions, such as spreading service failure related rumours, withdrawal of patronage, and so on. Since customers access Internet Banking services through the user interfaces via the websites, it means that such interface designs should follow best practices and highest standards. Though no singular Internet Banking System may be termed as superior over the rest of the others in the world, it is necessary that system designers should be contemporary, innovative and customer-centric. One way to achieve this is by studying what is obtainable in the industry with the view of improving on the existing expertise. This work is a computational analysis of the current trends in Internet Banking user interface designs, with cases studies drawn from some selected Nigerian banks. Some of the outcomes of this research are the User Interface Functionality (UIFA) Chart, and the User Interface Similarity Analysis (UISA) Chart.

Abstract - Digital imaging and Communications in Medicine (DICOM) is a standard developed for handling large amount of pictorial information in Medical imaging. With the vast availability of medical imaging applications like computed tomography, magnetic resonance, digital radiography, radiation therapy and ultra sound, the need for storing, printing, transmitting and retrieving biomedical images became obligatory. As per the DICOM standard, the images are basically retrieved based on the textual information associated with every DICOM image. This research proposes Content based retrieval of DICOM images which will aid in retrieval of semantically relevant images without need for providing any additional information. This is achieved by classification based multimodal image retrieval. A combination of low level features and high level features are extracted for initial filtering of images. The classification of the images is done with the help of neural network where optimization process is incorporated for weight calculation which aids in effective classification of images. The relevance of classified images to query image is further optimized by using fuzzy c-means algorithm.

Abstract - With the widespread use of tablets and smartphones the demand for data services is increasing exponentially. WiMAX and LTE networks provide high speed data services to the end users but it is no match to the end user requirements. The users browse multimedia content websites or social media services and watch videos on wireless networks. The wireless devices of today consume high bandwidth. For example, the iPhone can use 24 times the spectrum of a traditional cell phone, while the iPad uses 122 times as much. This explosive growth of wireless device users has increased bandwidth requirements and enterprises are evaluating methods to make the available infrastructure more efficient. One such method is to use optimization techniques at TCP & HTTP level. In this study, we compare and evaluate HTTP and TCP optimization techniques. These techniques decrease bandwidth congestion, make the existing infrastructure more efficient, and improve the end-user experience at the same time.
