Detection Of Ddos Attacks And Flash Events Occuring Simultaneously In Network Traffic Using Deep Learning Techniques

ABSTRACT Recently, the advancement of technology and internet contributes to the increase of the network traffic over the globe. It improves digital services delivery over the global network such as online shopping, television, and streaming. However, as digital services become one of the de facto applications over the internet, a number of attacks on them have been increasing which raise security concerns. Some of the major attacks are Distributed Denial of Service (DDoS) and Flash Events (F...

Investigation Of Public Exposure To Radiated Emf From Cellular Base Stations: A Case Of Dodoma Urban

ABSTRACT There has been a proliferation of base station towers in recent years due to an expansion of mobile telephone networks. This has been accompanied by an increase in the level of community concern about possible health effects from the radio frequency (RF) radiation emissions from antennae mounted on the base station towers. The researcher aimed at measuring RF electromagnetic energy (EME) levels and compare with the maximum permitted limit for general public exposure given by Interna...

Performance Evaluation Of Multiple Access Techniques For Broadband Power Line Communication Systems

ABSTRACT Powerline communication (PLC) is a promising technique for information transmission using existing power lines. Broadband over power lines is the way of providing internet services to customers using high frequency signals integrated in the power wiring. The internet signals are modulated and coupled into the overhead power lines. The signals are decoupled at the consumer’s premises. BPL can be a solution for people living in any rural area where there is electricity, since the co...

Investigating The Impact Of FTM And IDM-IMMobility Models On The Performance Of Voice Codecs In Vanet

ABSTRACT Vehicular Ad-hoc Network (VANET) is a subclass of Mobile Ad-hoc Network where by vehicles on the road network are able to exchange data. Many automobile manufacturers make vehicles which are pre-equipped with devices such as Geographical Position System (GPS), Radar and Lidar, Bluetooth, Onboard LTE module. Therefore, in the future, Selfdriving cars will be available in many countries and voice communication between vehicles will present many services ranging from safety to non-safe...

Design Of An In-Home Multicarrier Broadband Power Line Communication System For Tanzania Homes

ABSTRACT Indoor broadband power-line communication (BPLC) networks with different number of branches, different terminal load impedance, different line length and impulsive noise using OFDM were considered. Earlier investigations have shown that the power-line channel suffers from multipath effects along with impulsive noise. In this dissertation the OFDM system was designed based on Anatory et al model using the impulse responses of typical Tanzania indoor power-line networks. It was observe...

Prototype For Multimedia Content Delivery Based On Ntc Enhanced Viterbi Algorithm

ABSTRACT Due to tremendous growth of multimedia applications over networks such as the Internet, multimedia traffic causes network congestion, which results into packet loss due to transmission errors resulted by low data transmission reliability. Forward Error Corrections techniques, have been proposed to increase data transmission reliability at the price of bandwidth expansion due to high channel code rates. This is because multimedia files are large in size (in Megabytes), therefore, high...

Fading Issues In Wireless Communication Systems: A Case Study Of Airtel Tanzania Limited

ABSTRACT This dissertation intends to present various fading problems affecting particularly wireless signal transmission over water and over thick forest and analyze its underlying principles in communication network. The dissertation also investigates various techniques used in practice to mitigate effects of fading over the said terrains. The dissertation is motivated by the fact that mobile companies, Airtel Network in particular, still suffer from fading in their transmission networks de...

Analysis Of The Impact Of Soil Electrical Conductivity On Magnetic Induction-Based Communication Between Underground And Aboveground Network Devices

ABSTRACT Magnetic induction (MI) is a physical layer technology that is effective for underground wireless communications. The underground communications involve three major communication links, namely underground to underground (UG2UG), underground to aboveground (UG2AG), and aboveground to underground (AG2UG). AG2UG and UG2AG links are special in a sense that they cross two different media, which are soil and free space. While this is the case, the soil electrical conductivity (EC) is prove...

Performance Analysis Of Free Space Optical Communication Under The Effect Of Scintillation In Mwanza And Arusha Regions Of Tanzania

ABSTRACT Free Space Optics communications (FSO) has drawn a bunch of attention for a range of applications in telecommunications field. The unregulated bandwidth which is up to 200THz, security, higher speed, unlimited data rate, low deployment cost, and shortest installation time frame are the few reasons to employ FSO system. However, weather attenuation has a massive impact on the FSO transmission channel. In this study, the effect of scintillation on the performance and FSO link availabil...

Investigation Of Interference In The Coexistence Between 4th Generation And Broadband Over Power Line

ABSTRACT Communication is the basis of all human interactions in the world. Thus, human beings have been struggling for years to introduce different communication transmission technologies. Lately, the two technologies namely Broadband over Power Line (BPL) and 4 th Generation/Long Term Evolution (4G/LTE) have been trending topics. Many researchers have been researching these technologies from different angles to make them better for use. There is a co-existence between BPL and LTE technolog...

FACTORS AFFECTING THE CAPACITY OF TANZANIA INDOOR POWERLINE NETWORKS

ABSTRACT In this study the factors affecting the capacity of indoor powerline networks were investigated. In order establish the factors, first the frequency response at various loads was determined using Anatory et al model. Then the mathematical approximation was used to determine the PSD of noise in dBm/Hz. The mathematical approximation represented the noise of a typical indoor channel similar to that obtained by Liu et al for indoor channel. Since, because of the limitations on the tran...
