Mobile Ad-hoc networks
Terminals may appear and disappear anywhere and anytime, and may freely move.
Nodes can act as routers or terminals.
Networks are independently formed and can be merged and split anytime.
Dynamic topologies.
Coexistence of different access mediums.
The network is intelligent and self-organized.
Bandwidth-constrained, variable capacity links.
Energy-constrained operation.
It has limited physical security.
Challenges increased by ad-hoc networks
Limitations of the wireless network.
Lack of central entity for organization available.
Limited range of wireless communication.
Packet loss due to transmission errors.
Variable capacity links.
Frequent disconnections/partitions.
They have limited communication bandwidth.
Broadcast nature of the communications.
Limitations imposed by mobility.
It is dynamically changing topologies/routes.
Lack of mobility awareness by system/applications.
Limitations of the mobile computer.
Short battery life.
Limited capabilities.
Build a wireless ad-hoc network
Try to build a network without infrastructure, using the networking abilities of the participants.
This is an ad-hoc network - a network constructed “for a special purpose”.
Simplest example: Laptops in a conference room - a single-hop ad-hoc network.
