Abstract: A lot of effort and time is utilized in the planning and building of the cellular wireless networks to use minimum infrastructural components to provide the best network coverage as well as delivery of quality of service. Generally, path loss models are used for the prediction of wireless network coverage. Therefore, detailed knowledge of the appropriate path loss model suitable for the proposed geographical area is needed to determine the coverage quality of any wireless network d...
Abstract: Wireless sensor networks (WSNs), an emerging large-scale network system can be embedded for any application. The designers of wireless sensor network have to consider the quality of service agreements from a user perspective. The WSN is very rapid in dynamic changing topology and has less energy, computing and communication resources.The network design has to fulfill the QoS parameters like reliability, timeliness and lifetime of the network. In wireless sensor network, when two no...

The huge progress of VLSI technology enables the integration of millions of transistor on a single chip called System on chip (SoC).The SoC uses AMBA (Advanced Microcontroller Bus Architecture) as on chip bus protocol. AMBA’s specifications define five buses/interfaces: Advanced extensible Interface (AXI), Advanced High-performance Bus (AHB), Advanced System Bus (ASB), Advanced Trace Bus (ATB), and Advanced Peripheral Bus (APB). AXI, AHB, ASB, ATB which are high performance buses used to in...
ABSTRACT There are great technological advancements in global application of ICT and hence the need for its use in teaching Biology. Lack of application of ICT in pedagogy might have led to poor performance in science subjects like Biology. The study sought to investigate the influence of integration of ICT in teaching Biology on students’ performance in secondary schools. The specific objectives of the study were: to find out the ICT resources available in the schools for use in teaching ...
Abstract Although e-learning provides enormous opportunities, its implementation in Universities in the developing world is low. Many people are sceptical about its effectiveness to serve as an alternative means to attaining higher education. There are limited studies within developing countries centred on e-learning adoption and utilisation. This study sought to find out the major challenges facing e-learning adoption at the Centre for Continuing Education (CCE), University of Cape Coast, (...
