Anticipating context changes using a model-based approach requires a formal procedure for analysing and modelling their context-dependent functionality, and a stable description of the architecture which supports dynamic decision-making and architecture evolution. This article demonstrates the capabilities of the context-oriented component-based application-model-driven architecture (COCA-MDA) to support the development of self-adaptive applications, we describe a state-of-the-art case study and evaluate the development effort involved in adopting the COCA-MDA in constructing the application. An intensive analysis of the application requirements simplified the process of modelling the application's behavioural model, therefore, instead of modelling several variation models, the developers modelled an extra-functionality model. COCA-MDA reduces the development effort because it maintains a clear separation of concerns and employs a decomposition mechanism to produce a context-oriented component model which decouples the applications' core functionality from the context-dependent functionality. Estimating the MDA approach's productivity can help the software developers to select the best MDA-based methodology from the available solutions proposed in the literature. Thus, counting the source line of code is not adequate for evaluating the development effort of the MDA-based methodology. Quantifying the maintenance adjustment factor of the new, adapted, and reused code is a better estimate of the development effort of the MDA approaches.

this paper describes a new model for proactive messages delivery to mobile phones. SpotEx application can use any Wi-Fi access point as presence sensor that could activate delivery for some user-generated messages right to mobile phones. The key idea is how to associate some user-defined messages and Wi-Fi access points. As a result we can build rule-based expert system that describes delivery of user-defined messages depending on visibility of Wi-Fi hotspots.

Many diseases are diagnosed based on cell count done by clinical examination. The methods which are being used in pathological laboratories for counting cells in a sample are the traditional manual and tedious ones. This procedure is laborious and dependent on the judgment and skill of the operator. Moreover the judgment of the operator may vary in relation to fatigue and other physical conditions. Importantly these techniques consume long periods of time which may affect diagnosis. In order to improve the efficiency and veracity of diagnosis, this paper presents an algorithm that automatically counts the cells using windows based applications in mobile phones. The algorithm uses the quintessential preprocessing techniques to remove the graininess in the sample images, enhances the contrast between the cytoplasm and nucleus and extra cellular components [15]. Subsequently, the segmentation algorithm based on Otsu’s threshold, morphological operations, and marker controlled watershed algorithm and cell size considerations is performed. Pathologists can now prepare and image thousands of samples and save on time per day using this automation.

A mobile ad hoc network (MANET) is a set of wireless mobile nodes that can communicate with each other without using any fixed infrastructure. It is also necessary for MANET devices to communicate in a seamless manner. There are multiple routing protocols that have been developed for MANETs. There is a need to support real time and multimedia applications in MANETs as they gain popularity. MANETs require an efficient routing protocol and quality of service (QoS) mechanism in order to support multimedia applications such as voice and video. Such applications have strict quality of service requirements such as bandwidth, delay, and jitter. Design and development of routing algorithms with QoS support is experiencing increased research interest. This paper evaluates the QoS performance of MANETs by comparing the results of using AODV and DSR routing protocols. Using the OPNET Modeler, we have conducted an extensive set of performance experiments for these protocols with a wide variety of settings. The results show that DSR would be the best protocol to use with voice based traffic as long as mobility is kept to a minimum. As network size and mobility increases, AODV is the better choice due to the on-demand nature allowing for much higher mobility because of the non-caching nature of the routes. However, when resource intensive applications such as voice and video are introduced, the on-demand nature of AODV severely hampers network performance. Even with QoS, AODVs route discovery cannot keep up with the requirements of these applications and this is where DSR's route caching truly shines.

In this paper, the construction of space time block (STBC) over maximum rank distance (MRD) codes is presented for different configuration of transmit antennas. Different fields are used to construct such codes. To conserve the rank of the code, Gaussian integers have been used for modulation for 3-transmit antenna scenario to evaluate their performance. Furthermore, a comparative study with corresponding orthogonal code is also presented. First, It is shown through simulation that rank codes in any antenna configuration can achieve full diversity gain similar to what orthogonal codes can do in most cases. The simulation results show that orthogonal codes generally perform better than MRD for any given configuration. However, a special case is described in which rank code outperforms orthogonal code for 2x1 antenna configuration provided the two conditions are satisfied.

In this paper a high throughput, low latency, mobility adaptive and energy efficient medium access protocol (MAC) called Mobility Adaptive (MA) for wireless sensor networks. MAMAC ensures that transmissions incur no collisions, and allows nodes to undergo sleep mode whenever they are not transmitting or receiving. It uses delay allocation scheme based on traffic priority at each node and avoids allocating same back off delay for more than one node unless they are in separate clusters. It also allows nodes to determine when they can switch to sleep mode during operation. MA-MAC for mobile nodes provides fast association between the mobile node and the cluster coordinator. The proposed MAC performs well in both static and mobile scenarios, which shows its significance over existing MAC protocols proposed for mobile applications. The performance of MA-MAC is evaluated through extensive simulation, analysis and comparison with other mobility aware MAC protocols. The results show that MA-MAC outperforms significantly the existing CSMA/CA, Sensor Mac (S-MAC), Mobile MAC (MOBMAC), Mobility aware Delay sensitive MAC (MD-MAC) and Dynamic Sensor MAC (DS-MAC) protocols including throughput, latency and energy consumption.

A large number of attractive services, which combine the functionality of mobile terminals with existing services on the Internet, are spreading. The service delivery platform (SDP) can provide more attractive services by collaborating with telecommunication carrier services. SDP-based services are provided through collaboration among reusable service components, referred to as "enablers". As the number of such collaborative services increases, the peak load on the collaboration process and particular enablers will increase and the load will fluctuate widely. Although these increase the number of servers constituting the SDP for providing stable collaborative services at peak loads, a large amount of server resources could be wasted under conditions other than peak load times. In order to continue to provide stable collaborative services without wasting server resources, it is desirable to improve the efficiency of server resources with the result that the number of running servers can be increased or decreased without shutting services down depending on the load. To realize this, we propose an enhanced SDP architecture that features a distributed enabler-collaboration and enabler-relocation mechanism. We implement the proposal on real PC-servers, and evaluate the proposed architecture to verify its effectiveness.
