wireless sensor networks(wsn) have unique properties that distinguished them from other wireless networks and have special challenges. not-chargeable, not-changeable and limited power supplies of sensor nodes is the most important challenge of this networks, and if the power supply of node expired, a part of data maybe lost. because of the importance of covers in wireless sensors, in this work ...

Wireless Sensor Networks (WSN) limited resources in terms of processing capability and power supply raise a variety of challenges which make them a fertile ground to numerous investigation efforts. Increasing the sensing range, maintaining and improving the connectivity, or extending the lifetime represent the main objectives of WSN researches. In this paper we propose an approach for the deplo...

• Using regional brackish water resources to create supply networks. Variations in groundwater salinity over time were modeled at a high spatial resolution. The lowest cost network is determined while mixing of with different salinities considered. Small variations demand cause large differences the optimal costs. WaterROUTE model links modeling long term planning. Water users can reduce their ...

Underwater Wireless Sensor Networks (UWSN) share the common challenges of terrestrial Wireless Sensor Network (WSN), however they are significantly different from terrestrial WSN. Mainly, because acoustic wireless communication is the main physical layer technology in UWSN. Acoustic communication offers longer range, but has limitations due to low speed of sound, high error probability, limited...

This paper proposed a novel centralized hardware fault detection approach for a structured Wireless Sensor Network (WSN) based on Naïve Bayes framework. For most WSNs, power supply is the main constraint of the network because most applications are in severe situation and the sensors are equipped with battery only. In other words, the battery’s life is the network’s life. To maximize the networ...

The wireless sensor network (WSN), is a type of self-organized distribution system without complex infrastructure requirement. However, WSN’s independence and un-attended usage limit its power supply and life expectancy. These become a critical issue for any WSN implementation. The in-network processing which, intends to minify data volume locally can greatly reduce the energy consumption of da...

Microbial fuel cells (MFCs) are envisioned as one of the most promising alternative renewable energy sources because they can generate electric current continuously while treating waste. Terrestrial Microbial Fuel Cells (TMFCs) can be inoculated and work on the use of soil, which further extends the application areas of MFCs. Energy supply, as a primary influential factor determining the lifeti...

The objective of this research paper is to design and implement wireless sensor networks (WSN) for various monitoring & control applications in industry. In today’s competitive market the industries are facing growing demands to improve process efficiencies to comply with environmental regulations and meet corporate financial objectives. Therefore, the Wireless Sensor Network (WSN) for industri...

The demand for applications involving Wireless Sensor Network (WSN) or RFID systems is increasing. The sensor in a WSN and RFID tag/reader in a RFID system are called resource constrained devices because these devices have limited processing power, memory size and energy supply. The information transmitted among these low resource devices must be protected from unauthorized access using specifi...
