Explain in detail the complete  architecture of the Infrastructure and Ad hoc Network.

Following are the details of the architecture of the infrastructure and Ad hoc network-

Infrastructure Network

Infrastructured network is a wired network. All the stations are connected to a fixed wired network. All the wireless devices are connected to a fixed point known as Access Point(AP). AP is responsible for any type of communication between the nodes. When any node wants to communicate with any other node, the first node needs to communicate with AP then Access Point will transfer its message to the other node. In other words, we can say that infrastructure network has a central access point for transmission of information. This type of network does not provide flexibility. Also this type of architecture is fit for large coverage area. However, interference and noise often acts as a barrier in communication. This network also offers great complexity in the detection and configuration of faults. Also re installation is costly and requires periodically maintenance. It becomes costly as the distance increases to a some extent. It is a permanent type of network used for reliable communication.

Ad hoc Network

Ad hoc network does not has any central access point. Every node is connected to another node physically. It is a temporary network setup generally for emergency purposes. This network lacks access point. In this architecture communication is done directly between the nodes. This type of network provides great flexibility. Also this type of network is fit for smaller coverage area. Interference and noise easily hinder the communication between the nodes. However, detecting an error is easy in ad hoc network as compared to infrastructure network. Also configuring and re installation is quite economical as well. These networks do not need much maintenance. This network is costly for a small coverage area. Also the transmission of information is not reliable as compared to infrastructure network. But they are very useful for emergency purposes like during flood, earthquakes etc. The transmission is not very secure but offers good speed and serves the requirement for communication in need.

So this is all about the Infrastructure and Ad hoc networks and their architectures.
