Abstract

IEEE 802.15.4 standard is widely used in wireless personal area networks (WPANs). The devices transmit data during two periods: contention access period (CAP) by accessing the channel using CSMA/CA and contention free period (CFP), which consists of guaranteed time slots (GTS) allocated to individual devices by the personal area network (PAN). However, the use of GTS slot size may lead to severe bandwidth wastage if  the traffic pattern is not fit or only a small portion of GTS slot is used by allocated device. The proposed scheme devides the GTS slot and then optimizes the GTS slot size by exploiting the value of superframe order (SO) information. The proposed scheme was tested through simulations and the results show that the new GTS allocation scheme perform better than the original IEEE 802.15.4 standard in terms of average transmitted packets, throughput, latency and probability of successful packets.

Abstract

Pada era digital sekarang, pemanfaatan teknologi multimedia digunakan pada berbagai bidang, terutama pariwisata. Virtual tour yang merupakan bagian dari virtual reality hadir untuk memberi manfaat ke masyarakat untuk mendapatkan pengalaman baru dengan melakukan tur secara dunia maya ke tempat wisata tertentu. Kegiatan ini menyajikan proses dan hasil dari kegiatan pengabdian masyarakat yang bekerja sama dengan Pemerintah Kota Surabaya untuk mengembangkan aplikasi virtual tour Taman Harmoni berbasis website. Dengan lima tahapan pelaksanaan, dari observasi lapangan hingga dokumentasi, kami dapat mempublikasikan aplikasi tersebut dengan laman web yang bisa diakses oleh masyarakat dimanapun dan kapanpun. Sebanyak 71,4% pengunjung aplikasi yang telah mengeksplorasi fitur-fitur yang disediakan memberikan umpan balik yang baik terhadap keberadaan aplikasi ini.
