Traditional wireless networks including wireless sensor networks working in an unlicensed spectrum band are suffered from uncontrolled interference, as this unlicensed spectrum band gets crowded day by day. This problem is not because of spectrum band deficiency, rather it is because of the misuse/inefficient usage of the spectrum bands i.e., fixed spectrum(More)
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)
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 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)
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)
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)
