Wireless Sensor Networks (WSNs) are intended for monitoring an environment by sensing it, then collecting data, processing it and finally transmitting it to final destination. These sensor nodes have some constraints due to their limited energy, storage capacity and computing power. Data are routed from one node to other using different routing protocols. There are ...

The cloud is widely advertised as a silver bullet for many IT-related challenges of Small and Medium-sized Enterprises (SMEs). While it can potentially have a number of attractive benefits, many SMEs refrain from using cloud sourcing and cloud services because of high upfront costs for building the appropriate knowledge in the enterprise, for searching and ...

In an organization if employee wants to transfer information regarding the work to another employee, it is not possible manually if that organization is big which has so many departments, So at this case the user have to use technique to transfer information as soon as possible. If some changes had happened in any department ...

Transmission Control Protocol (TCP) provides end to end transmission service which provides a significant contribution in congestion control in the network. TCP throughput is better in wired network than in wireless network, because TCP first designed to work in wired network. The main problem with TCP in wireless network is that no differentiation between network ...

Computer programming is a process that leads from an original formulation of a computing problem to executable programs. Understanding the fundamentals of computer programming is considered a difficult task for students. This paper aims to identify the programming topics that are difficult for the students to learn and determine the factors that affect their learning ...

The combination of digital multimedia element such as graphics, audio, cartoon, animation and text could create an interesting and interactive learning environment for preschool children. Preschool may not a place where formal education is imparted but yes, it definitely is a place where children have their first taste of independence. Preschool education is the provision ...

In database distribution system anything can be considered as data e.g. number, person name, phone no, etc. when a data is meaningful, it is called information. The database is an organized collection of related information. Database management system is collection of interrelated data and set of application program to access those data. A database is ...

ACO (Ant Colony Optimization) is a well – known metaheuristic in which a colony of artificial ants cooperates in explain Good solution to a combinational optimization problem. Wireless sensor consisting of nodes with limited power is deployed to gather useful information from the field. In wireless sensor network it is critical to collect the information ...

In this paper, a survey on Wireless Sensor Network (WSN) and their technology, standards, prototype and applications was carried out. A wireless sensor network consists of thousands of inexpensive miniature devices capable of computation, communication and sensing. It provides a bridge between both the real and virtual worlds. Allow the ability to observe the previously ...
