   • What is a Wireless Access Point?

     A Wireless Access Point (WAP) is a networking device that allows connecting the devices with the wired network. A Wireless Access Point (WAP) is used to create the WLAN (Wireless Local Area Network), it is commonly used in large offices and buildings which have expanded businesses.

     It is easier and simpler to understand and implant the device. It can be fixed, mobile or hybrid proliferated in the 21st century. The availability, confidentiality, and integrity of the communication and network are a responsibility and to be ensured about that.

      A wireless AP connects the wired networks to the wireless client. It eases access to the network for mobile users which increases productivity and reduces the infrastructure cost.

     Advantages  of Wireless Access Point (WAP):

   • Wireless Sensor Network (WSN)

     Wireless Sensor Network (WSN) is an infrastructure-less wireless network that is deployed in a large number of wireless sensors in an ad-hoc manner that is used to monitor the system, physical or environmental conditions. 

     Sensor nodes are used in WSN with the onboard processor that manages and monitors the environment in a particular area. They are connected to the Base Station which acts as a processing unit in the WSN System.  Base Station in a WSN System is connected through the Internet to share data.

   • What is WRAN (Wireless Regional Area Network)?

     WRAN which stands for Wireless Regional Area Network is designed and brought to existence, especially for rural areas, developing countries, places with low population density. IEEE 802.22 is the standard developed for Wireless Regional Area Network which uses white spaces of the Radio Frequency (RF) spectrum to provide the broadcast connection in the areas that are difficult to reach. White spaces are the unused part of a frequency spectrum. This is done with the help of cognitive radio (CR) which is designed for wireless systems to CPEs avoid interference and crowding. 

     WRAN is performed in unused channels in the Television (TV) spectrum to get finer propagation of signal at low frequencies. WRAN is the first system that was to regulate the effective use of unused broadbands of the TV spectrum with less interference all around the world.

     Need of WRAN : The prerequisites needed to use frequency spectrum are very high and the use of the entire spectrum is not efficient. A report taken from 2004 to 2005 proclaimed that only 5.2% of the entire spectrum is in use, which called the need to design a network...

   • What is a Network Address?

     A computer network is a group of some interconnected computers that are sharing a common or different resources provided on or by network nodes. These sharing or communication between the machines is governed by some set of rules or network protocols. These computers or machines are identified by network addresses, and may have hostnames.

     A Network Address is a logical or physical address that uniquely identifies a host or a machine in a telecommunication network. A network may also not be unique and can contain some structural and hierarchical information of the node in the network. Internet protocol (IP) address, media access control (MAC) address and telephone numbers are some basic examples of network addresses. It can be of numeric type or symbolic or both in some cases.

     <img alt="IP addressing">

     Network Addressing :

     It is the prime responsibility of the network layer to assign unique addresses to different nodes in a network. As mentioned earlier they can be physical or logical but primarily they are logical addresses i.e. software-based addresses.  The most widely used network address is an IP address. It uniquely identifies a node in an IP network....

   • What is a Network Operating System?

     The basic definition of an operating system is that the operating system is the interface between the computer hardware and the user. And in daily life, we use the operating system on our devices which provides a good GUI, and many more features with it. Similarly, a network operating system(NOS) is software that connects multiple devices and computers on the network and allows them to share resources on the network. Let’s see what are the functions of the network operating system.

     Functions of the NOS : Following are the main functions of NOS :

     • Creating and managing user accounts on the network.
     • Controlling access to resources on the network.
     • Provide communication services between the devices on the network.
     • Monitor and troubleshoot the network.
     • Configuring and Managing the resources on the network.

     Now let’s see the type of Network Operating systems.

    A WSN consists of spatially distributed sensors, and one or more sink nodes (also called base stations). Sensors monitor, in real-time, physical conditions, such as temperature, vibration, or motion, and produce sensory data. A sensor node could behave both as data originator and data router. A sink, on the other hand, collects data from sensors.
