Difference Between Infrastructure and Infrastructure Less Network

Computer Network is a collection of two or more computers. It helps users to communicate more easily. In this article we will see difference between infrastructure and infrastructure less network.

Infrastructure Network

Infrastructure networks are networks with pre-defined infrastructure and it is made from fixed-size of nodes. Here network services are delivered through pre-constructed infrastructures. In this network Access point is the central controller for each device. Access points are nothing but fixed base stations that are connected by wires. It is impossible for remote localities to install such a network as it is too expensive. All devices on a wireless network are communicated through a router i.e. access point. Examples are Wireless LAN, satellite networks, etc.

Infrastructure-less Network (Ad hoc Networks)

This type of network is a group of independent terminals that communicate with each other by forming a radio network. The links in wireless networks have less bandwidth as compared to the wired networks. In this network, each node is act as a router, and network connection is distributed among nodes. In an ad-hoc network, the formation of networks takes place dynamically with the help of a collaboration of random nodes. Examples of infrastructure-less networks are Wireless Sensor Networks(WSN), and Mobile Ad hoc networks (MANETs).

Differences between Infrastructure and Infrastructure-less Networks

Infrastructure Network	Infrastructure-less Network (Ad hoc)
This network is faster than Ad hoc network.	This network is slower than infrastructure network.
This network provides more security options.	This network provides fewer security options.
In this network access point handles all wireless nodes which are present in range.	There is no need for access point in Ad hoc networks.
Applications are IEEE 802.11 and HIPERLAN2.	Bluetooth is a type of Ad hoc network.
This network used frequently in hotel lobbies, airport lounges, train stations, etc.	This networks are frequently used in the military, local networks are used for communication among a fixed group of people, etc.
For the set up of a permanent network, an infrastructure network is used.	For the set up of a temporary network, an Ad hoc network is used.
