This paper provides an in-depth study and analysis of the optimization of sports event management systems using wireless sensor networks. Aiming at the monitoring task of a directed wireless sensor network in a three-dimensional environment, the directed sensing nodes scattered inside the designated monitoring area in a random deployment manner usually have uneven distribution and other problems; we analyze the characteristics of the directed sensor nodes, probabilistic sensing model, and the cooperative sensing model of multiple sensor nodes for monitoring target points and propose a sensing optimization strategy in polar coordinates to guide the three-dimensional plane directed orientation adjustment and sensing optimization of sensor nodes, thus enhancing the sensing capability of network nodes. The experimental results confirm that the algorithm can improve the coverage of the area to be monitored and the quality of sensing service, and it reduces the overall energy consumption of the network by using the distributed node synchronization scheduling mechanism to extend the life cycle of the network to maintain good monitoring capability under the premise of the limited total usage of the directed nodes in wireless sensor networks. The application of wireless sensor network technology in sports competition management mainly includes the application of smart wearable devices in sports competition training, the application of goal-line technology in sports competition, and the application of eagle eye technology in sports events, all three technologies have certain advantages in the application of sports competition, and all of their help to promote the improvement of sports event management and the development of sports industry; the second aspect is wireless sensor. The second aspect is the application of wireless sensor network technology in sports event information management, which is mainly used to collect information related to sports events and fully utilize it to make sports event management more informative and digital, which is helpful to improve the level of sports event management; the third aspect is the application of wireless sensor network technology in sports event stadium management, which is mainly based on intelligent stadiums to create a more spectator-friendly and good experience for the audience, a more ornamental and good experience viewing place, to promote the development and growth of sports industry.

Wireless Sensor Network technology is a wireless network consisting of several individual sensor nodes that are used to monitor the condition of a place and can interact with its environment by means of sensing, controlling and communication of physical parameters. The application of Wireless Sensor Network Technology to the water turbine as a power plant is used for remote control and monitoring of the water turbine. So that it allows users to get maximum and real time information without having to be in the sensor area, in the sending and receiving of information using the Wireless HC-12 module with a frequency range of 432 MHz. HC12 Wireless Transceiver that can receive information on the Master Controller device and can send requests to the microcontroller on the server device. In this subsystem there is a MAX232 IC as a converter that converts the RS232 level signal from a TTL level signal on the HC12 Wireless module to a data communication that can be displayed on a computer. Keywords: Artificial Inteligent, Embedded System, Microkontroller, Visual Basic, Wireless Sensor Network

<p><em>Abstrak</em> - <strong>Keamanan rumah menjadi hal yang sangat penting ketika pemilik rumah meninggalkan rumah dalam keadaan kosong. Selain pencurian, kebakaran juga merupakan masalah yang sering kali terjadi ketika rumah ditinggal pemiliknya. Sebagai alternatif solusi untuk menjaga dan mengawasi rumah yang diajukan pada penelitian ini ialah menggunakan teknologi Jaringan Sensor Nirkabel yang terintegrasi dengan jaringan internet, sehingga pemilik rumah tetap dapat mengawasi keadaan rumah dari jarak jauh. Pada penelitian ini dirancang prototype sistem rumah pintar atau Smart Home yang memanfaatkan teknologi Jaringan Sensor Nirkabel menggunakan standard Zigbee. Beberapa node sensor ditempatkan pada peralatan rumah, dimana setiap node dapat saling berkomunikasi secara wireless dan terpusat di node kordinator. Selanjutnya node kordinatior akan terhubung ke jaringan internet sehingga pemilik rumah dapat membuka aplikasi smart home kapan saja dan dimana saja. Rancangan sistem <em>Smart Home</em> disimulasikan menggunakan rumah model untuk menguji kinerja perangkat <em>Smart Home</em>. Pengujian kinerja Smart Home dimulai dengan pengujian keakurasian masing masing data sensor hingga waktu respon komunikasi dari sensor ke pusat monitoring. Tingkat error pembacaan suhu disetiap ruangan ialah 1 - 4.27%. Sensor PIR berhasil mendeteksi keberadaan orang di suatu ruangan dengan waktu delay </strong><strong>adalah 2.8 detik dengan jarak maksimal 5 meter</strong><strong>. Fungsi kendali dan monitoring (<em>on/off</em>) perangkat elektronik bekerja dengan baik, dengan waktu respon kurang dari 1 detik. Dari hasil pengujian komunikasi nirkabel antar node, diperoleh bahwa jarak maksimal antar node ialah sekitar 20 m, dengan rata-rata waktu respon pengiriman data ialah 1-2 detik. Adapun waktu respon mengalami delay mencapai 2 detik apabila beberapa perintah kendali dilakukan pada waktu yang bersamaan.</strong></p><p> </p><p><strong><em>Kata Kunci - </em></strong><em>Smart Home</em>, Jaringan Sensor Nirkabel, Zigbee.</p><p> </p><p><em>Abstrak</em><strong> - Home security becomes very important when homeowners leave the house empty. In addition to theft, fire is also a problem that often occurs when the house left the owner. As an alternative solution to maintain and supervise the homes submitted in this study is to use Wireless Sensor Network technology integrated with the Internet network, so that homeowners can still monitor the state of the house remotely. In this study designed prototype smart home system or Smart Home which utilizes Wireless Sensor Network technology using Zigbee standard. Some sensor nodes are placed in the home equipment, where each node can communicate wirelessly and centrally at the coordinator node. Next node coordinate will be connected to the internet network so that homeowners can open smart home application anytime and anywhere.

Background: It is important to improve the quality of service by using congestion detection technology to find the potential congestion as early as possible in wireless sensor network. Methods: So an improved congestion control scheme based on traffic assignment and reassignment algorithm is proposed for congestion avoidance, detection and mitigation. The congestion area of the network is detected by predicting and setting threshold. When the congestion occurs, sensor nodes can be recovery quickly from congestion by adopting reasonable method of traffic reassignment. And the method can ensure the data in the congestion areas can be transferred to noncongestion areas as soon as possible. Results: The simulation results indicate that the proposed scheme can reduce the number of loss packets, improve the throughput, stabilize the average transmission rate of source node and reduce the end-to-end delay. Conclusion: : So the proposed scheme can enhance the overall performance of the network. Keywords: wireless sensor network; congestion control; congestion detection; congestion mitigation; traffic assignment; traffic reassignment.
