Abstract

Pandemi COVID-19 memberikan dampak pada berbagai aspek kehidupan yang mengakibatkan pembatasan ruang gerak manusia, salah satunya pada dunia pendidikan. Kebiasaan baru dengan balajar dari rumah harus didukung dengan kualitas jaringan bagus. Kualitas jaringan yang bagus dapat diukur melalui parameter QoS. Selain itu, kondisi jaringan yang bagus tentunya sesuai dengan tingkat layanan di sisi pengguna. Pada penelitian ini kami mengukur QoS dan QoE. Parameter QoS yang digunakan meliputi throughput, packet loss, delay, dan jitter. Sedangkan parameter QoE yang digunakan adalah MOS. Berdasarkan hasil pengujian yang dilakukan pada 2 video, menunjukkan bahwa parameter-parameter tersebut masih berada pada nilai standar yang digunakan oleh ITU-T G.1010. Sedangkan berdasarkan hasil survei yang dilakukan pada mahasiswa dan dosen di IT Telkom Purwokerto didapatkan hasil MOS menunjukkan bahwa video pembelajaran online memiliki kualitas yang bagus.

Abstract

Mobile ad-hoc network is a wireless network with variable topology and communication routes. In a MANET network, nodes have the role of finding and handling routes to each node in the network. There are several challenges such as bandwidth, power, and direction of movement of nodes. A routing protocol is needed to determine the route and ensure that the packets sent successfully arrive at their destination to solve this problem,. In large-scale networks, the routing structure requires redundant route information, resulting in frequent overhead. We investigated the use of the LEACH protocol as a hierarchical protocol to solve the network overhead. The proposed research also adds a PSO algorithm to optimize the performance of the LEACH protocol. The research method uses simulation methods and evaluation of routing models using Network Simulator. Evaluation is prioritized on the use of traffic TCP and UDP. The results show that TCP traffic has better delay, packet loss, and PDR values compared to UDP traffic when using the LEACH protocol. When the PSO algorithm is added, the delay value in TCP traffic decreases by 47%, the packet loss value decreases by 78%, and the PDR value also increases by 0.1%.
