Abstract

Forest fire is a problem that always occurr in the tropic areas when entering the dry season. To be able to anticipate forest fire early, it is necessary to have a remote detection system. WSN is one of systems that can detect and monitor forest fire remotely by placing node sensors on the location. In this application, there is a possibility that node sensors burned because of fire. This paper aims to investigate the performance of clustering routing protocol applied in WSN for forest fire application. There are three clustering routings analyzed; LEACH, LEACH-C and Modified LEACH.. Simulations were carried out using NS-2.35 software with measured parameters were throughput, packet loss, and energy consumed. The simulation results show that when the number of burn nodes increases, the throughput and packet loss of LEACH and LEACH decrease. Mean while , these performance index tend to stable in Modified LEACH. In term of energy consumed Modified LEACH the same pattern as in the throughput and packet loss. There is a significant in the number of energy consumed on LEACH-C in contrast, it rise slowly in LEACH.Keywords : Clustering Routing Protocol, WSN, Forest fire

Abstract

One alternative energy that is easy and can be used is wind. This energy is utilized through wind turbines which have two general types, namely horizontal and vertical axis wind turbines. This wind turbine can move by utilizing the energy available in the wind to rotate the turbine. The problem with wind turbines is self-starting is difficult to achieve. This can be caused by several factors, such as slow wind speed and erratic wind direction. In addition, wind turbines also have low-efficiency values. Therefore, our contribution to this research is to design a blade controller on a vertical axis wind turbine. This blade control is designed by utilizing the pitch angle by using actuators that are applied to each blade based on the Proportional, Integral & Derivative (PID) algorithm. The PID algorithm is used to find the appropriate pitch angle value on a vertical axis wind turbine. The effect of the pitch angle on the wind turbine serves to maintain the mechanical power value by the available power in the wind. This research was conducted using a simulation method (MATLAB). In this study, it was found that this wind energy conversion simulation produces maximum mechanical power when the wind speed varies is 1723 Watt and when the wind speed is 7 m/s, mechanical power achieved is 362.595  Watt.

Abstract

Transmission control protocol (TCP) employs acknowledgement (TCP-ACK) for every transmitted packets to ensure reliable transmission. As a result, it sends the next window packets after receiving the TCP-ACK packet of previous window. This means that the earlier the TCP-ACK packet arrives, the faster the TCP next window transmission and the better the TCP performances. To do so, there should be a special treatment to the transmitted TCP-ACK to fasten next window transmission. This paper proposes a collision probability reduction for the transmitted TCP-ACK packets so that the overall TCP delay reduces. Collision probability reduction can be implemented in many ways. Initially, mathematical analysis is provided to prove that method can work as expected. The mathematic analysis shows that when TCP-ACK collision probability is reduced, the overall TCP delay is also reduced. The proposed method is then implemented in 802.11, 802.16 and complex networks. The NS-2 simulations evaluations for the aforementioned networks and the proposed method proved that collision reductions on TCP-ACK exert average TCP delay reductions about 11.86%, 28.04% and 9.46% subsequently.The proposed method is also applicable for other TCP types.

Abstract

Universitas Riau menggunakan media Fiber Optik (FO) untuk mendukung penggunaan internet dan intranet. Saat ini, UR menjalin kerja sama dengan PT. Telkom yang menyediakan koneksi internet dengan bandwidth 90 Mbps. Sementara untuk jaringan backbone local, yang menghubungkan antar gedung di lingkungan UR dan terhubung ke gateway internet, digunakan FO dengan topologi star. Sistem multimode dengan topologi star yang tidak memiliki jalur cadangan yang berbeda dari jalur utama dan telah berumur 15 tahun lebih, tidak akan mampu untuk mendukung kebutuhan bandwidth, performa yang diinginkan dan reliability dalam waktu mendatang. Perancangan jaringan baru dengan estimasi bandwidth, peforma dan reliabity yang mendukung berbagai layanan ke depannya dilakukan dengan memperhitungkan power budget, risetime budget dan bandwidth. Demi mendukung kebutuhan bandwidth dalam 30 tahun lebih ke depan, dialokasikan bandwidth 1 Gbps.
