Abstract - MANET is an abbreviation for mobile ad hoc
network it is also referred to as wireless ad hoc network it is
an uninterrupted self-configuring, infrastructure-less network
of mobile devices connected without making use of wires. In a
MANET architecture, devices can move independently in any
direction and therefore changes their links to other devices
frequently. Because MANETs are transportable, they utilize
wireless connections to interact with different networks. In
this article an overview to MANET along with its utilization in
wireless systems will be discussed. A brief consideration
regarding the types of MANET architectures and its
advantages and disadvantages in wireless communication
networks is being done in this article.
Key Words: Features of MANET, Architecture of MANET,
Routing protocols, Challenges, Applications of MANET.
1. INTRODUCTION
MANET is an ad hoc network which does not require any
infrastructure support for carrying data packets between
two nodes. MANET is an ad hoc network for mobile or much
simply called as mobile ad hoc network which is a
continuous self ordered, infrastructure-less network of
mobile devices connected wirelessly. Mobile ad hoc
networks possess a flat network infrastructure. It has a
shared medium which is highly demandable for radio
communication. In MANET architecture every computer or
node means any device is a router as well as end host. The
nodes or devices in the MANET architecture are in general
autonomous. MANET has a dynamic topology architecture
which highly promotes mobility. In the MANET architecture,
every node also works as a router since they route packets
for other nodes.
1.1 FEATURES OF MANET
There are various features of MANET as listed below:
Partitioned operations
Autonomous terminal
Multi hop routing
Dynamic network topology
Fluctuating link capacity
Light weight terminals
Partitioned operation: The nodes engaged in a MANET
should cooperate among themselves. Every node is
behaving like a relay.
Autonomous Terminal: In MANET architecture every
mobile terminal is an autonomous node which may
operate as a host or a router. Therefore end points and
switches cannot be identified.
Multi hop routing: In multi hop MANET transmitting data
packets from a source to destination out of direct wireless
transmission range the packets are to be transmitted
through one or more intermediate nodes.
Dynamic network topology: The mobile nodes in the
network dynamically create routing between themselves
as they move forward forming their own network.
Fluctuating link capacity: In MANET one communication
path is shared by many sessions. The channel on which
the nodes communicate is subjected to noise, fading, and
interference, and has less bandwidth than a guided
network. In some cases the path between any pair of users
can traverse multiple wireless links and the link
themselves can be heterogeneous.
Light weight terminals: Mostly MANET nodes are mobile
devices with less CPU processing capability, small
memory size and low power storage.
2. MANET ARCHITECTURAL MODEL
The architectural model for MANET preserves the integrity
of the IP architecture while allowing for the particularities of
MANETs.
