INTRODUCTION
Wireless ad-hoc network is a decentralized type of wireless network. The network is ad hoc because it does not rely on a preexisting infrastructure, such as routers in wired networks or access points in managed (infrastructure) wireless networks. Instead, each node participates in routing by forwarding data for other nodes, and so the determination of which nodes forward data is made dynamically based on the network connectivity. In addition to the classic routing, ad hoc networks can use flooding for forwarding the data.
Wireless ad hoc networks can be further classified by their application:
• Mobile ad-hoc Networks (MANET)
• Wireless Mesh Networks (WMN)
• Wireless Sensor Networks (WSN)
An ad-hoc network is made up of multiple “nodes” connected by “links”.
A Mobile Ad-Hoc Network (MANET) is a self-configuring infrastructure less network of mobile devices connected by wireless. ad hoc is Latin and means "for this purpose".. MANETs are a kind of wireless ad hoc networks that usually has a routable networking environment on top of a Link Layer ad hoc network.
Types of MANET
• Vehicular Ad-hoc Networks (VANETs) are used for communication among vehicles and between vehicles and roadside equipment
• Intelligent vehicular ad-hoc networks (InVANETs) are a kind of artificial intelligence that helps vehicles to behave in an intelligent manner during vehicle-to-vehicle collisions, accidents, drunken driving etc.
• Internet Based Mobile Ad-hoc Networks (iMANET) are ad-hoc networks that link mobile nodes and fixed Internet-gateway nodes. In such type of networks normal adhoc routing algorithms don't apply directly.
