Introduction to MANET and Clustering in MANET

Chapter 3: Applications of MANET:
With the increase of use portable devices as well as progress in wireless communication, ad hoc networking is gaining importance. Ad hoc networking can be applied anywhere, where there is no communication infrastructure or the existing infrastructure is expensive or difficult to implement. Ad hoc networking allows the devices to maintain links to the network as well as easily adding as well as removing devices to and from the network. The set of applications for MANETs is diverse, ranging from large-scale, mobile, highly dynamic networks, to small, static networks that are constrained by power sources. Besides the inheritance applications that move from traditional infrastructure environment into the ad hoc context, a great deal of new services can and will be generated for the new environment. Typical applications include:
3.1 Defense (Military battlefield applications):
In modern battlefield requires robust and reliable (secure) communication military battlefield in many forms. Most communicating nodes are installed in mobile vehicles used for defense. Defense personnel could carry telecomm devices that could talk to a wireless base station or directly to other telecom devices if they are within the radio range. However these forms of communication are considered to be primitive. At times when wireless base station is destroyed by enemy, a soldier will be prohibited from communicating with other soldiers if the called party is not within the radio range. This is the scenario where mobile ad hoc networks come into play. Ad hoc networks are well known as self organizing networks since they are robust when nodes disappear due to destruction or mobility. Through multi hop communication soldiers can communicate to remote soldiers via data hoping and data forwarding from one radio device to another.
3.2 Sensor Networks:
Another application of MANETs is sensor networks. This technology is a network composed of a very
