What is the wireless sensor network manager?
The wireless sensor network manager can perform management tasks and obtain useful information using the configuration, performance, and fault tabs in the network management tab. These special features include deployment, sensing coverage, system life and faulty sensor nodes.
What is a sensor node in a wireless sensor network?
Sensor nodes in wireless sensor networks are spread over a region and communicate using point-to-point wireless communication. Sensor nodes collect, process, and send data obtained from an environment. Wireless sensor networks can use three different nodes. Common node: This node collects environment information and then sends data to a sink node.
How can we improve wireless sensor network management efficiency?
Many researchers have attempted to improve wireless sensor network management efficiency. A Simple Network Management Protocol (SNMP)-based sensor network management system was developed that is a convenient and effective way for managers to monitor and control sensor network operations.
What sensors do I need for a Smart Desk and room booking?
The type of sensors you need for your smart desk and room booking system depends on the level of granularity and accuracy you’re looking for. If you simply want to sense if there’s anyone in a room (or not), a room occupancy sensor will give you a straightforward yes/no answer.

In this paper, we have studied the IT system (e.g. MS-outlook) that is used to book meeting rooms in a corporate environment. In the existing IT system, the status of meeting rooms is manually entered, and as a result, it is not reflected in real time in the IT system.

What is wireless sensor network?
Wireless sensor networks have garnered considerable attention recently. Networks typically have many sensor nodes, and are used in commercial, medical, scientific, and military applications for sensing and monitoring the physical world. Many researchers have attempted to improve wireless sensor network management efficiency.
How does sensor network work?
The ability of sensor networks to sense, communicate and process data has led to the rapid development of such networks. Many researchers have attempted to improve wireless sensor network management efficiency. Wireless sensors networks can sense and monitor information from the physical world, and are used in the scientific, medical, …
What is sensor node?
Sensor nodes usually relay a data stream to a base station or command node (management node) based on a regular rule or event. Sensor nodes in wireless sensor networks are spread over a region and communicate using point-to-point wireless communication.
What is SNMP based on?
SNMP is based on the manager and agent model, which consists of a manager, agent, and management information database . The manager model provides an interface between a human manager and a management system. The agent model provides an interface between the manager and the physical device being managed (Figure 1).
Why is power limited in sensor networks?
Because sensor nodes are battery powered, power is a limited resource for all sensor networks. By examining sensing coverage and identifying the areas in which sensor node coverage overlaps, network managers can deactivate redundant sensor nodes temporarily until other nodes run out of power. 4.3.
Can a network manager read the coordinates of sensors in each sensor node?
Additionally, the network manager can read the coordinates of sensors in each sensor node. Furthermore, the network manager can determine that no sensor node exists in the rectangular area and that the density of nodes in the circular area is excessive.
What is smart wireless management?
Smart Wireless Management allows the system to constantly monitor the availability and load of channels. When traffic increases it seamlessly and automatically switches to free channels, without interruption or interference.
What is standard Wi-Fi?
Standard Wi-Fi technology for co-existence with other Wi-Fi networks. The system is based on standard Wi-Fi according to the IEEE 802.11n standard, and operates in 2.4 and 5 GHz, meaning that the system is visible in the network, so that other Wi-Fi access points will recognize the DICENTIS Wireless Access Point …
What is a WAP router?
The WAP includes a built-in web browser that enables true wireless configuration and connection without the need for a wireless router , and provides extended functionality and tablet control with easy and intuitive user interface. Two WAPs can be set up to create wireless redundancy and maximize reliable communication and meeting continuity.
What is WPA2 encryption?
All wireless signals within the system are encrypted with WPA2, a highly secure standard encryption method used by mobile devices to guarantee protection against tapping or eavesdropping. As the system uses standard Wi-Fi, it can follow the WPA2 standards as they evolve.
What is packet loss detection?
Packet Loss Concealment allows the system to automatically predict what a damaged or lost packet should be and fills the gap, resulting in continuous audio without losses. This is a unique capability that no other competitive product offers.
What is Bosch microphone?
Advanced audio processing enables the microphone and loudspeaker to be active at the same time, resulting in a face-to-face meeting experience. The system also makes use of built-in and intelligent Acoustic Feedback Suppression developed by Bosch. It automatically adapts itself to the environment and maximizes speech intelligibility when higher volumes are required.
What is an infrared sensor?
Infrared array sensors. These sensors allow you to detect moving or motionless objects, temperature distribution, thermal image, and moving direction by measuring the temperature as a person or object moves nearer or further away from the sensor.
What are occupancy sensors?
What are the different types of occupancy and movement sensor? 1 Desk occupancy sensors These simply stick to the underside of a desk. The PIR sensor has a hood covering half of the sensor, so only detects motion within a 180-degree radius. Coupled with a narrow-angle lens, this makes it highly accurate, detecting just a person under a desk, and not people walking behind or to the side of it. 2 Table occupancy sensors Similar to desk sensors, these stick to the underside of a table and use a narrow-angle lens. However, the PIR sensor detects motion within a 360-degree radius, so can detect people sitting around a table. Based on average table height, the detection range is 0.5m. 3 Room occupancy sensors These stick to the ceiling and have a 360-degree field of view and use a wide-angle lens to detect people within a wider field of view. Based on a typical 2.5m ceiling height and 64-degree detection angle the estimated detection range is 5m. 4 Cubicle occupancy sensors As with desk sensors, these detect a 180-degree view, so can be placed on a wall or ceiling of a cubicle to detect people within that space and avoid those walking past. These are great for toilets or meeting cubicles.
What is a person flow sensor?
People-flow sensors Detecting people and the direction of movement, these can be used to monitor real-time people flow in and out of any single-occupant doorway. Bi-directional, they detect people as they walk towards or away from the sensor, so you can determine the number of people in a space.
How does a sensor work?
These sensors work by detecting heat emitted by people. When a person enters a sensor’s field of view, the sensor detects motion and tells you someone is present within that space. The sensor continues to monitor the space and can send you regular occupancy updates.
Reducing energy consumption within buildings has been an active area of research in the past decade; more recently, there has been an increased influx of activity, motivated by a variety of issues including legislative, tax-related, as well as an increased awareness of energy-related issues.
