Description
Summary:Wi-Fi is widely used to connect electronic devices wirelessly using ISM radio bands.Previous studies have reported traffic congestion in Wi-Fi due to several reasons.As an alternative, unused spectrum in TV band known as TV white space (TVWS) can be utilized for the same purpose. The use of Wi-Fi technology in TV band is also known as White-Fi. TVWS ranges in VHF and UHF that is not utilized by licensed user in a particular time and location. This paper presents a network performance comparison between Wi-Fi and White-Fi by evaluating the average throughput, end-to-end delay and packet delivery ratio (PDR). The simulation result shows White-Fi (IEEE 802.11af) has a significant percentage of average throughput and PDR with 25.94% and 24.06% compared to Wi-Fi (IEEE 802.11g) respectively.In addition, the percentage of average end-to-end delay in White-Fi is 60.79% lower than Wi-Fi.
