MOBILE AD HOC NETWORK MOBILE AD HOC NETWORK ABSTRACT ABSTRACT : Mobile Ad Hoc Networks (MANETs) refer to a class of wireless network that can be formed dynamically and randomly without the need for infrastructural setups. Such networks are able to adapt and reconfigure themselves on the fly according to node mobility and changing network topologies. These characteristics are particularly attractive to the military user due to the inherent unpredictability of the tactical environment. MANET technology has its roots in defence, having been developed from military research efforts. This paper presents an overview of MANET technology, its key characteristics and how it can be leveraged for the Third Generation Singapore Armed Forces. Experience gained and lessons learnt from an experiment initiated and funded by the Future Systems Directorate on MANET are also discussed .

INTRODUCTION : INTRODUCTION : A Mobile Ad Hoc Network (MANET) is an interconnected system of wireless nodes which communicate over bandwidth-constrained wireless links. Each wireless node can function as a sender, a receiver or a router. When the node is a sender, it can send messages to any specified destination node through some route. As a receiver, it can receive messages from other nodes. When the node functions as a router, it can relay the packet to the destination or next router in the route. When necessary, each node can buffer packets awaiting transmission . The nodes move randomly; hence at a given point in time, an ad hoc network exists between the nodes, giving rise to an arbitrary network topology. MANETs can be dynamically formed among any group of wireless users and require no existing infrastructure or configuration . MANET CHARACTERISTICS MANET CHARACTERISTICS : : A MANET has several marked characteristics . FIRST , it does not have a centralised infrastructure. It is unlike the traditional mobile wireless networks in which base stations, access points and servers have to be deployed before the networks can be used. Figure 1(a) illustrates how an infrastructure-based wireless network would operate1 . Figure 1a. Infrastructure-based wireless network Instead, as shown in Figure 1(b) , the ad hoc network is decentralised, with all mobile nodes functioning as routers and all wireless devices being interconnected to one another. Intuitively, this means that the MANET is also a self-configuring network in which network activities, including the discovery of the topology and delivery of messages, are executed by the nodes themselves .
