Access to Agricultural Market Information by Rural Farmers in Tanzania
(International Journal of Information and Communication Technology Research, 2014-07)
Access to agricultural markets and agricultural market information is essential for participating in agricultural markets. A skilled and well-equipped participant benefits more in the agricultural marketing chain. Due to ...
Comparison of Empirical Propagation Path Loss Models for Mobile Communication
(Computer Engineering and Intelligent Systems, 2014)
Empirical propagation models have found favor in both research and industrial communities owing to their speed
of execution and their limited reliance on detailed knowledge of the terrain. In mobile communication the
accuracy ...
An Overview of Various Propagation Model for Mobile Communication
(Pan African International Conference on Information Science, Computing and Telecommunications, 2014)
System’s propagation characteristics through a medium is one of the important task to be done before planning and optimization of any network in order to estimate the signal parameter accurately for mobile system. Propagation ...
Optimization of Hata Model based on Measurements Data using Least Square Method: A Case Study in Dar-es-Salaam – Tanzania
(International Journal of Computer Applications, 2014-09)
ABSTRACT
In this study, we present a measurement-based model for path loss prediction in three GSM service areas at 900 MHz .Modified Hata model for rural, suburban, and urban environments were derived in this study on ...
Wireless Sensor Node for Gas Pipeline Leak Detection and Location
(International Journal of Computer Applications, 2014-08)
Many different wireless sensor nodes for gas pipeline leak
detection and location has been proposed but still there are
challenges particularly on environmental issues and signal
accuracy. This paper discusses theories ...
Mathematical model for the effects of treatment and vaccination controls on the dynamics of rotavirus disease with reference to Uganda
(SCIK Publishing Corporation, 2014)
In this paper, while Rotavirus has been a recognised disease for a long time in developing countries
like Uganda, the control of this endemic disease is still a challenge. We formulated a mathematical model for the
dynamics ...
Development of an Access Point Positioning Algorithm under the Changing in Environment and Users’ density Estimation
(Asian Journal of Computer and Information Systems, 2014-06)
In many wireless networks a single hop is all that is needed or in fact tolerable. The physical region where network is available is known as a coverage area. Generally, a transmitter and a receiver may exchange data by ...
Assessment of non transmittable codewords enhancement to Viterbi Algorithm Decoding
(LJS Publishing, 2014-09)
Researchers have shown that practical mobile communication channels introduce errors that are concentrated in a certain locality rather than random errors. These are burst errors caused by deep fading of the wireless channel ...
Multifunctional network monitoring system using SMS
(IEEE, 2014-07-14)
Network monitoring is very important for the reliable operation of any network, monitoring is not only concerned with the monitoring of its performance and availability, but also monitoring of network operating environment, ...
Air Pollution Monitoring System based on Wireless Networks - Simulation
(Innovative Systems Design and Engineering, 2014)
Air pollution is one of environmental issues that cannot be ignored. Industrial growth and urbanization results in
the air pollutants concentrations in many areas. These pollutants can cause damages in human health and ...
