This manuscript proposes an agricultural environment monitoring server system for monitoring information concerning an outdoors agricultural production environment utilizing Wireless Sensor Network (WSN) technology. The proposed agricultural server collects environmental, agricultural land, seeds and soil information on the outdoors through WSN-based environmental and soil sensors, collects snaps information through CCTVs, area information through RFID and collects location information using GPS modules. This collected information is converted into data and saved in to a database through the agricultural server consisting of a sensor manager, which manages information gathered from the WSN sensors, an image information manager, which manages image information collected from CCTVs, RFID and a GPS manager, which processes location information of the agricultural server system, and provides it to producers. In addition, a solar cell-based power supply is implemented for the server system so that it could be used in agricultural environments with insufficient power infrastructure. This agricultural server could even monitor the environmental information on the outdoors, and it could be look forward that the use of such a system could participate to increasing crop yields and improving quality in the agricultural field by supporting the decision making of crop producers through analysis of the collected information.

Range Free

Location information is the most important for wireless sensor network (WSN). Due to the limitation of energy, cost and influence of environment, range-free localization schemes are more suitable for WSN despite of their low localization accuracy. Two methods, which are improved grids SCAN and multiple locating and averaging scheme, are presented to improve localization accuracy of range-free localization schemes and performed through performance evaluation based on ROCRSSI (Ring Overlapping based on Comparison of Received Signal Strength Indicator). By simulation it is concluded that ROCRSSI applying both methods can get better localization performances.

ABSTRAKLampu sinyal memiliki peranan yang penting dalam persinyalan kereta api. Pemeliharaan lampu sinyal perlu diperhatikan agar kondisi lampu sinyal tetap sesuai standar. Penelitian ini merancang Wireless Sensor Network (WSN) untuk mengakuisisi parameter lampu sinyal agar dapat dipantau, dianalisis, dan disimpan. Parameter yang diakuisisi berdasarkan dari standar peraturan Menteri Perhubungan Indonesia mengenai lampu sinyal kereta api antara lain intensitas cahaya, tegangan, suhu, dan kelembapan lingkungan lampu sinyal. Sistem tersusun dari tiga subsistem, yaitu sensor node, gateway, dan server. Sistem dapat melakukan pemantauan intensitas lampu sinyal, suhu dan kelembapan lingkungan lampu sinyal, serta tegangan lampu sinyal yang dikirim secara nirkabel yang dapat mencapai jarak hingga 200 m memanfaatkan spektrum radio frekuensi 433 Mhz. Pada saat ada gangguan terhadap lampu sinyal, sistem telah mampu melakukan predictive maintenance berdasarkan standarisasi lampu sinyal.Kata kunci: lampu sinyal, sensor node, gateway, server, wireless sensor network ABSTRACTSignal lights has an important role in railway signaling. Proper maintenance must be taken to maintain signal lights so that signal lights condition remain in accordance with the standard. This study designed the Wireless Sensor Network (WSN) to acquire signal lights parameter information so that it can be monitored, analyzed and stored. The parameters acquired are based on the Indonesian Minister of Transportation's regulatory standards regarding railway signal lights such as light intensity, voltage, temperature, and humidity of signal lights. System consists of three subsystems, namely sensor node, gateway, and server. System can monitor signal lights intensity, ambient temperature, ambient humidity, and voltage of signal lights then send those parameters which can reach distances of up to 200 m utilizing the radio frequency spectrum 433 Mhz. When there are interferences with signal lights, system has been able to perform predictive maintenance based on the signal lights standardization.Keywords: signal lights, sensor node, gateway, server, wireless sensor network

State Information

Location information plays a remarkable role in wireless sensor networks in collecting information to support distributed spectrum sensing and directional wireless charging. To decide the optimal operating frequency band of wireless sensor network, the location information of the wireless sensor network nodes should be known to fulfill the geographical map of the spectrum using the technique of distributed spectrum sensing. In addition, wireless charging also needs the location information of the wireless sensor network node for the directional wireless charging is much more efficient than the omnidirectional wireless charging. The location of the wireless sensor network node is estimated by Wi-Fi signal because the Wi-Fi infrastructures are widely deployed not only for Internet wireless access but also for the communication between wireless sensor network nodes. The most of our daily life is spent in the indoor environment, and the channel state information is one of the most important parameters of fingerprint in indoor localization. The channel state information is not a constant parameter for various timing synchronization and frequency offset even in the same location; therefore, a new parameter—normalized amplitude of channel state information—is proposed to be a robust parameter, which is insensitive to timing synchronization and frequency offset. In this article, we first formulate the received signal in a multipath channel by taking timing synchronization and frequency offset into consideration, then we derive the closed-form expression of channel state information, and propose the new parameter—normalized amplitude of channel state information. Finally, the robustness of the new parameter is verified by numerical simulations.

Wireless Sensor Network (WSN) technology, for services that are difficult to access or which need to be continuously monitored regardless of location, needs further research and development due to an expansion of fields where it can be applied and due to increases in efficiency. In particular, in the field of defense, research on the latest IT technologies including sensor networks is being actively conducted as an alternative to the risky use of personnel in areas such as surveillance and surveillance reconnaissance. This paper experimented with analyzing the conditions necessary for increasing the energy efficiency of the nodes constituting a sensor network using a clustering routing technique and a location-based routing technique. The derived factors include a method for selecting a cluster head (CH), a method for establishing a path from each channel to a base station (BS), and a method for transmitting collected data. We experimented with the derived factors and proposed a WSN configuration method that increases the energy efficiency of each node by applying optimal results and methods that were verified experimentally.

Blockages in sewage pipelines are difficult to be cleaned or extracted. In order to manage sewer blockage proactively sewer managers needs to be able to identify the location of blockages precisely. As of now, only humans do this sully job of cleaning the sewages. Many human right organizations have been advocating to stop this inhuman activity. Even the highest court in the land has admonished the government to stop forth with this job of cleaning. Respective government’s corporation is adapting cleaning machines to suck the clogs and sewage water from respective blockage points. As an alternative solution, using modern technology, we present our paper on how an acoustic based sensor could be used to detect the blockages automatically as well as transmitting this information using the wireless sensor network to the centrally monitored server system. This will help in taking immediate action of removing the clogs instantly. This will not only save cost but also enable instant solution.
