Streaming video merupakan sebuah teknologi yang mampu mengirim file audio dan video dari sebuah server melalui suatu jaringan dalam ukuran yang lebih kecil. Efisiensi dan manajemen dalam penggunaan jaringan wireless menjadi hal yang penting dalam membangun suatu jaringan streaming video. Besarnya bandwith, serta kecepatan pengiriman data pada wireless yang akan digunakan dalam streaming video akan mempengaruhi kualitas hasil streaming video. Penelitian dilakukan menggunakan perangkat lunak Network Simulator versi 2 (NS2) dengan menggunakan cygwin agar dapat berjalan pada sistem operasi Windows. Pemodelan dan simulasi didasarkan pada parameter spesifikasi wireless cisco aironet 1130AG dan mengacu kepada standar IEEE 802.11a dan IEEE 802.11b. Kinerja jaringan pada streaming video menggunakan protokol IEEE 802.11a dan 802.11b dengan melakukan beberapa variasi keadaan dan membandingkan kualitas kedua protokol. Hasil menunjukan bahwa pada protokol 802.11a menghasilkan kualitas yang lebih baik dalam penanganan layanan streaming video dibandingkan protokol 802.11b. Pada simulasi protokol 802.11a memberikan tingkat performansi nilai delay, paket loss, yang lebih kecil dibandingkan dengan simulasi menggunakan protokol 802.11b. Kata kunci--- Streaming video, IEEE 802.11a, IEEE 802.11b, Network Simulator, Pemodelan dan Simulasi. Video streaming is a technology that is capable of sending audio and video files from a server via a network in a smaller size. Efficiency in the use and management of wireless networks have become important factors in building a network of streaming video. The amount of bandwidth, as well as the speed of data transmission in wireless video streaming will be used in will affect the quality of streaming video. The study was conducted using the software Network Simulator version 2 (NS2) using cygwin to run on the Windows operating system. Modeling and simulation based on the parameters of the Cisco Aironet 1130AG wireless specifications and adhere to standards IEEE 802.11a and IEEE 802.11b. Network performance on streaming video using the IEEE 802.11a and 802.11b protocol by doing some variation of circumstances and compare the quality of the two protocols. The results showed that the 802.11a protocol produces better quality video streaming services in handling than the 802.11b protocol. In the 802.11a protocol simulations provide the level of performance value delay, packet loss, which is smaller than the simulation using the 802.11b protocol. Keywords--- Streaming video, IEEE 802.11a, IEEE 802.11b, Network Simulator, Pemodelan dan Simulasi.

Abstract Human need for information now pushing the demand for internet data access speed high rises rapidly. The service offers diverse include text, sound, video, and data. It has become even daily needs that can not be separated from human life. So the need for technology that can deliver voice, data, and video with better quality. This study discusses the application of scheduling service class on data communications applications in the Fixed WiMAX network. Fixed WiMAX network is simulated using OPNET Modeler. Network design performed using a single BS, SS 16 pieces, and the server as a source of traffic. Data is collected for ten minutes. The simulation results obtained show that the application of sound, UGS service class has the greatest value is 3 Mbps throughput and jitter smallest value that is close to 0 s. In video applications, rtPS service class has the greatest value of throughput is 44 Mbps and has the smallest delay value was 0.17 s. On the application file transfer, nrtPS service class has the greatest value is 6,745,187 bps throughput and has the smallest delay value is 0.014 s. In the web browsing application, nrtPS service class has the greatest value is 8.2 Mbps throughput and has the smallest delay value is 0.022 s.Keywords : fixed WiMAX, scheduling service, Opnet Modeler

Abstrak- Perangkap tikus pada penelitian ini memiliki fasilitas short message service (sms) yang bertujuan untuk memberikan informasi secepatnya bahwa ada seekor tikus yang terperangkap. Hal ini berguna untuk mengurangi resiko penyebaran penyakit akibat kematian tikus. Fitur lain yang ada pada perangkap ini yaitu perangkap ini akan mengirim sms setiap satu jam secara berulang sampai pengguna perangkap ini mematikannya dengan cara melakukan panggilan telepon pada nomor telepon yang ada pada perankap tikus ini. Setelah melakukan semua rangkaian kegiatan penelitian didapatkan bahwa perangkap tikus ini dapat mengirimkan sms dalam waktu rata-rata 27,68 detik dan dapat mengulangi pengiriman sms selama 1 jam dengan waktu toleransi 7 detik. Abstact- In this research mousetrap have short massage service facility that aims to give information quickly when rat is caught. This is useful for reducing the risk of death due to disease mouse. To know the rats are caught by using sensors photodiode that detects the presence of rats when infrared light direct to the photodiode blocked by mouse. Sending sms relay itself was controlled by microcontroller ATmega 8535 to move the keypad on the phone. Another features available on these traps are this trap will send sms repeated every one hour until this trap users deadly with a way to make phone calls on phone number that appears on this mousetrap.After a series of research found that this mousetrap can send sms in average time 27.68 seconds and can be repeated sms 1 hour delivery time 7 seconds tolerance. Keyword : Short message service (sms), sensor, relay
