Study Notes

Mobile Ad-hoc Networks (MANET)

  • A major concern in a MANET is security.
  • The purpose of a MANET in a military context is to provide a communication network in the battlefield.

Characteristics of MANET

  • MANET is a self-configuring, infrastructure-less network of mobile devices.
  • The links in a MANET are wireless.
  • The nodes in a MANET are mobile.
  • A characteristic of a MANET is that it is self-healing, meaning that it can rapidly respond to changes in the network.
  • A key characteristic of a MANET routing mechanism is that it is adaptive.
  • A characteristic of a MANET regarding scalability is that it can scale up to hundreds of nodes.
  • A characteristic of a MANET regarding network traffic overhead is that it has low overhead.

Challenges and Requirements

  • One of the challenges in a MANET is maintaining connectivity.
  • Another challenge is managing network topology and routing.
  • A requirement for a routing protocol in a MANET is that it must be able to adapt to changing network topology.

MANET Working Group

  • The Internet Engineering Task Force (IETF) created the Mobile Ad-hoc Networks (MANET) working group.
  • The purpose of the MANET working group is to develop a routing protocol for MANETs.
  • The MANET working group is currently pursuing an on-demand routing protocol.
