System Support for Managing Invalid Bindings

Lachhman Das Dhomeja, Yasir Arfat Malkani, Azhar Ali Shah, Khalil Khoumbati
2011 International Journal of UbiComp  
Context-aware adaptation is a central aspect of pervasive computing applications, enabling them to adapt and perform tasks based on contextual information. One of the aspects of context-aware adaptation is reconfiguration in which bindings are created between application component and remote services in order to realize new behaviour in response to contextual information. Various research efforts provide reconfiguration support and allow the development of adaptive context-aware applications

To this end, we propose and implement our design approach to reconfiguration to manage invalid bindings. The development and modification of adaptive context-aware applications is a complex task, and an issue of an invalidity of bindings further complicates development efforts. To reduce the development efforts, our approach provides an application-transparent solution where the issue of the invalidity of bindings is handled by our system, Policy-Based Contextual Reconfiguration and Adaptation (PCRA), not by an application developer. In this paper, we present and describe our approach to managing invalid bindings and compare it with other approaches to this problem. We also provide performance evaluation of our approach.

2019 University of Sindh Journal of Information and Communication Technology  
The research in Wireless Sensor Networks (WSNs) have increasingly been done since many year for its application-specific utilization. Depending on the environment, WSNs have been deployed for the sake data sensing, gathering and transmitting it to the nearest sink. Usually, the WSNs are small in size with limited computational capabilities. Therefore, an efficient routing scheme determine the usage of battery having minimal power. In this study, we develop a scenario with the deployment of
more » ... r nodes and sinks in the WSNs field. The sensor nodes are connected to the nearest possible sink. Then, we apply Genetic Algorithm (GA) with some basic modifications for the evaluation and optimization of the distance and energy consumption. If any node sensed the data and the path is optimized then the distance is reduced by multi-hop scheme, the lifetime of the sensor network is considerably maximized. Multi-hop routing scheme has an edge over the single hop or direct routing scheme where minimal energy is consumed in transmitting the data towards the nearest sink. For the sake of simulation, a variable number of sensor nodes with one or more sinks are deployed and the results are done in MATLAB. Further, these results are compared with TEEN (threshold sensitive energy efficient sensor network) protocol.

Findings: The research finds that literature on practices for identity fraud management is scattered. Findings also reveal that firms assume identity fraud issues as a technological challenge, which is one of the major reasons for a gap in effective management of identity frauds. This research suggests e-tailers to deal this issue as a management challenge and counter strategies should be developed in technological, human and organisational aspects. Research limitations: This study is limited to the published sources of data. Studies, based on empirical data, will be helpful to support the argument of this study, additionally future studies are recommended to include a wide number of databases. Originality: This research makes unique contributions by synthesising existing literature at each stage of fraud management and encompasses social, organisational and technological aspects. It will also help academicians understanding a holistic view of available research and opens new lines for future research. Practical implications: This research will help e-tail organisations to understand the whole of identity fraud management and help them develop and implement a comprehensive set of practices at each stage, for effective management identity frauds.

2019 Mehran University Research Journal of Engineering and Technology  
WSN (Wireless Sensor Network) comprises of small-sized and constraint-capability SN (Sensor Nodes) which record, send and receive data, sensed to a sink. The network lifetime and energy usability are important challenges to be dealt with. During the working of the SN, the maximum amount of energy is consumed than sensing and processing of data. Therefore, an efficient transmission of the data is required so that the energy can be saved. In this paper, a novel routing and scheduling method for
more » ... Ns using GA (Genetic Algorithm) is presented, where the sinks employed on four sides of the sensor field. These sinks collect the data from the SNs having the optimal distance towards the respective sink. The proposed scheme finds the optimized path using GA, during transmission of data from SN to the nearest sink. First, we run the GA for determination of routing paths, where a source SN finds the possible number of optimal hops. Second, the hops or intermediate relay SNs are assumed to relay the data towards the sink, efficiently. The performance is experimented and evaluated using MATLAB R2016b. The simulations have carried out through comparing the proposed scheme with TEEN (Threshold Sensitive Energy Efficient Sensor Network Protocol). The results of simulation comprise of 10 and 20 number of SNs, discretely. Additionally, the direct distance of each node is calculated and the distance through multiple hops from/to the nearest sink is also evaluated. The achievements of the proposed technique are to save both energy and distance for the sake of network longevity and optimal and precise data delivery by multiple hops.
