Introduction to Ad hoc Networks Seminar Topic:

It is an wireless network having a wide collection of nodes to terminals and that are autonomous. They form a radio network between them and maintain connectivity in decentralized manner. It is very easy to setup and its speed is very fast than other networks. It decreases the dependency of infrastructure. It can be connected from anything to anything like it can be connected between two vehicles. They are used in same type of work like in war all fighter planes, tankers, helicopters are connected to each through an ad hoc network and like fire brigade, taxi and ambulance.

Operating principles: it must have at least two nodes, with their respective network information’s. When the third node joins the network two possible outcomes are generated; firstly, new node establish connection with single hop communication with new node and secondly, any one identifies beacons signal and establish direct communication with the new node. When more network joins the network few nodes leaves the nodes.  Thus topology became more complex.

Hierarchal routing: it as an two way routing mean information can be send in two way that has node adjacent to more than one clusters which acts as gateway. Each node is divided into clusters and each cluster has node.

Flat routing: in this every nodes act as router. There is no need for choosing the cluster to recognize the network. They always execute shortest path or flooding type algorithm.

Proactive routing: in this node has to maintain a routing table for implementing of every other in the network. By this routing between a source and destination are always available.

Reactive routing: they determine path discovery process to the destination only when the node has a packet to transfer.
