Infrared Local Area Networks and P2P networks
IrLAN or Infra Red Local Area Network creates the possibility of connecting your computing device to an infrared receiver, which can process the data transmitted through a local area network to make them available on your device.
There are three ways to connect IrLAN to your device:
Important among the three methods of connecting IrLAN to your device is called the Peer-To-Peer (P2P) network, which works over a distributed network architecture on a decentralized basis. Nodes are planted on an individual basis in the system, to work both as consumer and supplier of resources, in contrast to the server models serving the clients in which the nodes representing clients access variety of data provided by the main servers. The individual nodes are known as peers.
In such a LAN the various tasks of file searching or video/audio reception, are shared by multiple peers that are inter-connected. Each peer make a part of their facilities like bandwidth, storage of data, power of processing, available to other peers without the necessity of communicating with the servers.
P2P networks are also part of IrLAN, used in a number of applications. While sharing of files is very common, which is in fact the reason for the popularity of such LAN networks, its uses extend to various other fields such as sending out messages instantly, and also for online chatting.
Various other P2P applications include Bitcoin which is a digital currency based on P2P, even the US military is trying to adopt P2P for warfare usage. Open Garden is another application where Internet connections are shared using Bluetooth or Wi-Fi.
In this IrLAN based P2P system, the providing and sharing of data are both done by the users. In contrast to the client to server basis, as more and more persons join the peer groups, the content is shared by all of them, which increases its capacity, which is a major feature of P2P networks.
