Improved spectrum allocation scheme for TV white space networks using a hybrid of firefly, genetic, and ant colony optimization algorithms

Autor: Jacob Bol Mach, Kennedy K. Ronoh, Kibet Langat

Publikováno v: Heliyon, Vol 9, Iss 3, Pp e13752- (2023)

This study proposes a novel hybrid Firefly Algorithm, Genetic Algorithm, and Ant Colony Optimization Algorithm (FAGAACO) for spectrum allocation in TV White Space (TVWS) networks. The Genetic Algorithm (GA) was used in the design to provide cross-ove

Design of a photonic crystal fiber for optical communications application

Autor: Kumbirayi Nyachionjeka, Hillary Tarus, Kibet Langat

Publikováno v: Scientific African, Vol 9, Iss , Pp e00511- (2020)

The desire for photonic crystal fibers (PCF) with small mode areas that can be used in nonlinear optics and optical communications is a never-ending and a continuously evolving research quest. By deliberately varying the diameters of air-holes and sp

Geospatial modelling of the inundation levels in the Sundarbans mangrove forests due to the impact of sea level rise and identification of affected species and regions

Autor: Manoj Kumer Ghosh, Lalit Kumar, Philip Kibet Langat

Publikováno v: Geomatics, Natural Hazards & Risk, Vol 10, Iss 1, Pp 1028-1046 (2019)

This research reveals the magnitude of mangrove area loss and future impacts on mangrove species composition and distribution due to rise in Mean Sea Level (MSL). In this study, a geospatial model of potentially inundated areas was developed using Di

Design and Analysis of a Multiple and Wide Nulling Collaborative Beamforming Scheme in the Domain of 3-Dimensional Wireless Sensor Networks

Autor: Robert Macharia Maina, Philip Kibet Langat, Peter Kamita Kihato

Publikováno v: International Journal of Antennas and Propagation. 2022:1-19

Null steering is essential in collaborative beamforming (CB) in wireless sensor networks (WSNs) to ensure minimal radiation power and interference in the direction of unintended receivers. Current research in null steering in CB in WSNs is mainly fro

Application of Spritz Encryption in Smart Meters to Protect Consumer Data

Autor: Lincoln Kamau Kiarie, Philip Kibet Langat, Christopher Maina Muriithi

Publikováno v: Journal of Computer Networks and Communications, Vol 2019 (2019)

The ongoing upgrade of the electrical power system into a more powerful system known as Smart Grid has both benefits and costs. Smart Grid relies on advanced communication and hence offers better services through improved monitoring, planning, and co

BER Performance of Stratified ACO-OFDM for Optical Wireless Communications over Multipath Channel

Autor: Zelalem Hailu Gebeyehu, Philip Kibet Langat, Ciira Wa Maina

Publikováno v: Journal of Computer Networks and Communications, Vol 2018 (2018)

In intensity modulation/direct detection- (IM/DD-) based optical OFDM systems, the requirement of the input signal to be real and positive unipolar imposes a reduction of system performances. Among previously proposed unipolar optical OFDM schemes fo
