In wireless sensor and actor networks cooperation among sensor and actor nodes introduces momentous gains compare to traditional sensing. For example, better precision in data collection by sensor nodes, and performing proper actions based on suitable decision by actor nodes. However, to get these possible gains, actor nodes need to be in proper positions.(More)
Software testing is a way of finding errors from the system. It helps us to identify and debug mistakes, errors, faults and failures of a system. There are many techniques and strategies emerged since the concept of software development emerged. The aim of testing is to make the quality of software as efficient as possible.in this paper we discuss most(More)
In these days, embedded system have an important role in different Fields and applications like Network embedded system , Real-time embedded systems which supports the mission-critical domains, mostly having the time constraints, Stand-alone systems which includes the network router etc. A great deployment in the processors made for completing the demanding(More)
Wireless communication networks using unlicensed frequency band faces certain challenges like unrestrained interfering and bad quality of transmission. To surmount the scarcity of frequency band, a new technique for wireless communication is compulsory to adapt the exponentially rising wireless communication demand. Visible light communication systems(More)
The objective of this research study is to better understand and measure student's attitudes and perceptions towards the effectiveness of mobile learning in higher education settings. This paper reports on the results of a survey of fifteen hundred students from different departments at Abdul Wali Khan University about their attitude and perception of using(More)
In asymmetric multihop wireless ad hoc networks the original medium access control protocol does not perform well, especially when the offered load is high. Many papers have studied these issues, and premeditated to obtain better fairness and throughput in multihop wireless ad hoc networks. These techniques provide some degree of fairness but either provide(More)
In this paper, we describe a simulation based health monitoring system test-bed for aircraft systems. The purpose of the test-bed is to provide a technology neutral basis for implementing and evaluation of reasoning systems on vehicle level and software architecture in support of the safety and maintenance process. This simulation test-bed will provide the(More)
Video watermarking is well known as the process of embedding copy right information in video bit streams. It had been proposed in recent years to solve the problem of illegal manipulation and distribution of digital video . In this study, an effective, robust DCT transform using MATLAB. In the proposed method, first the video frames are extracted from the(More)
