1. OVERVIEW
Emergence of the concept of multihop ad-hoc wireless networks, low power electronics, low power short-range wireless communication radios, and intelligent sensors are considered as the major technological enablers for the deployment of sensor networks (SNs). Our goal in this survey is to identify the key architectural and design issues related to sensor networks, critically evaluate the proposed solutions, and outline the m challenging research ost directions. The evaluation has three levels of abstraction: individual components on SN nodes (processor, communication, storage, sensors and/or actuators, and power supply), node level, and distributed networked system level. Special emphasis is placed on architecture, system software, and on challenges related to the usage of new types of components in networked systems. The evaluation process is guided by the anticipated technology trends, the current and the future applications. The main conclusion of the analysis is that the architectural and synthesis emphasis will be shifted from computation and communication components to sensors and actuators, and

    Abstract: A flood warning system incorporates telemetered rainfall and flow/water level data measured at various locations in the catchment area. Real-time accurate data collection is required for this use, and sensor networks improve the system capabilities. However, existing sensor nodes struggle to satisfy the hydrological requirements in terms of autonomy, sensor hardware compatibility, reliability and long-range communication. We describe the design and development of a real-time measurement system for flood monitoring, and its deployment in a flash-flood prone 650 km2 semiarid watershed in Southern Spain. A developed low-power and long-range communication device, so-called DatalogV1, provides automatic data gathering and reliable transmission. DatalogV1 incorporates self-monitoring for adapting measurement schedules for consumption management and to capture events of interest. Two tests are used to assess the success of the development. The results show an autonomous and robust monitoring system for long-term collection of water level data in many sparse locations during flood events.…

    I. I NTRODUCTION Wireless sensor networks have the potential to greatly benefit studies of volcanic activity. Volcanologists currently use wired arrays of sensors, such as seismometers and acoustic microphones, to monitor volcanic eruptions. These sensor arrays are used to determine the source mechanism and location of an earthquake or explosion, study the interior structure of the volcano, and differentiate true eruptions from noise or other signals (e.g., mining activity) not of volcanological interest. A typical campaign-type study will involve placement of one or more stations on various sites around a volcano. Each station typically consists of a few (less than five)…

    Due to the rise in demand for wireless sensor networks in recent times, significant shift is observed from traditional, wired technologies to upcoming wireless technologies. Asia-Pacific is expected to grow at the highest rate due to increase in production activities in APAC, huge population base, and lucrative government policies. China is, in fact, the growth engine for automation in Asia-Pacific; in spite of lower levels of plant automation. India is also gaining market shares worldwide.The WSN consists of "nodes" – from a few to several hundreds or even thousands, where each node is connected to one (or sometimes several) sensor. Each such sensor network node has typically several parts: a radio transceiver with an internal antenna or connection to an external antenna, a microcontroller, an electronic circuit for interfacing with the sensors and an energy source, usually a battery or an embedded form of energy harvesting. A sensor node might vary in size from that of a shoebox down to the size of a grain of dust, although functioning "motes" of genuine microscopic dimensions are yet to be created. The cost of sensor nodes is similarly variable, ranging from a few to hundreds of dollars, depending on the complexity of the individual sensor nodes. Size and cost constraints on sensor nodes result in corresponding constraints on resources such as energy, memory, computational speed, and communications bandwidth. The topology of the WSNs can vary from a simple star network to an advanced multi-hop wireless mesh network. The propagation technique between the hops of the network can be routing or flooding.…

    But these systems measure the vibrations and send the measured data using wires. If we need to add this type of vibration measurement system to any system which was already installed in its place all the present wiring needs to be altered and if there are more sensors to be used to measure these vibrations then wiring will be involved with more complexity. So in this project we are developing a wireless vibration measurement system where we can send the parameters measured through wireless technology. Depending on the application and range of distance for which data needs to be transmitted we can use different types of wireless technologies like wifi, zigbee or Bluetooth technologies. If the application involves continuous monitoring of data through online we can also use Ethernet module to store the data in online and can be monitored from anywhere through internet. Using this wireless technology is of great advantage as it helps to monitor the parameters easily. For this project we need to design separate boards with accelerometers, wireless module and microcontroller mounted on them to transmit the measure parameters and a gateway board with microcontroller and wireless module to collect the data from individual boards and for further processing. We can use this system as an on board battery operated or through external power. It all depends on the applications for…
