Abstract :

Efficient design and implementation of wireless sensor networks has become a hot area of research in recent years, due to the vast potential of sensor networks to enable applications that connect the physical world to the virtual world. Wireless sensor networks sense and collect data from a certain area, process and transmit them to the sink. If the distance of communication is large, messages are to be propagated through intermediate nodes. The main emphasis of this work is to find out and overcome limitations of the wireless sensor networks such as: limited energy resources, varying energy consumption based on location, high cost of transmission, and limited processing capabilities. The algorithms are mainly based on location, power levels, and load on the node, and their goal is to achieve better target sensing with minimizing the power consumption and maintenance throughout the network so that the majority of the nodes consume their power supply at relatively the same rate regardless of physical location. Different metrics will be used to calculate results employing some fixed iterations, and therefore an optimal solution can be formed throughout the simulation. A number of network topologies may be simulated with a pre defined set of parameters for optimal results. We have simulated some energy efficient protocols namely GRP (Geographic Routing Protocol), TORA (Temporally ordered routing algorithm), AODV (Adhoc on Demand Distance Vector Routing), OLSR (Optimized Link State Routing Protocol) and DREAM (Distance Routing Effect Algorithm for Mobility) and have analyzed the results on 6(six) various metrics.

Abstract :

This research work addresses the daily challenges encountered by loan applicants requesting for loan facilities from a loan scheme and the unnecessary end-to-end delays in the processing and some time the computational errors associated with the conventional ways of handling these task. An Automated Workflow Execution of loan transaction processing for distributed environment was designed as a result of the shortcomings attributed to the traditional system/environment for loan processing, web development tools such as Hypertext Markup Language (HTML), Hypertext Preprocessor (PHP), JavaScript, and MySQL were used to realize the web interface, and the distributed Automated Workflow Execution Engine for loan transaction processing. We achieved our objective in designing of the distributed software architecture and developing the web based automated workflow execution system to solve local loan transaction problems. A comparative evaluation in terms of features and functionalities was also done between the proposed system and five commercial automated workflow systems. Results revealed that the proposed system has lightweight architecture in terms of design patterns and the development tools used.
