Development of an Access Point Positioning Algorithm under the Changing in Environment and Users’ density Estimation
Kazema, Twahir; Kisangiri, Michael; Machuve, Dina (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 ... -
Development of an Algorithm for Optimizing Array Antenna Elements for Cellular Networks Using Evolutionary Computation
Kazema, Twahir; Michael, Kisangiri (International Journal of Digital Information and Wireless Communications, 2019-06)The discussion on a number of important issues and the state-of-the-art development of the model for optimizing antenna array element was done. An optimal radiation pattern as well as minimum side lobes levels were obtained ... -
Gain improvement of the Yagi-Uda Antenna Using Genetic Algorithm for Application in DVB-T2 Television Signal Reception in Tanzania
Kazema, Twahir; Michael, Kisangiri (Journal of Interdisciplinary Sciences, 2017-11-02)A Yagi-Uda Antenna, commonly known simply as a Yagi antenna or Yagi, is a directional antenna system consisting of an array of dipole and additional closely coupled parasitic elements (usually a reflector and one or more ... -
Investigation and analysis of the effects of geometry orientation of array antenna on directivity for wire-less communication
Kazema, Twahir; Michael, Kisangiri (Cogent Engineering, 2016-09-08)Array antennas offer a wide range of opportunities in the variation of their directivity patterns through amplitude and phase control. Directivity is one of very important parameters when optimizing Antenna. This paper ...
