Slide 3:

INTRODUCTION A MANET is a collection of wireless nodes. MANET is an autonomous system. The traffic types in ad hoc networks are Peer-to-Peer Remote-to-Remote . Dynamic Traffic

INTRODUCTION(Cont….):

INTRODUCTION(Cont….) MANET features: Autonomous terminal Distributed operation Multihop routing Dynamic network tpology Fluctuating link capacity Light-weight terminal

MANET Characteristics: :

MANET Characteristics : Communication via wireless means. • Nodes can perform the roles of both hosts and routers. • No centralized controller and infrastructure. Intrinsic mutual trust. • Dynamic network topology. Frequent routing updates. • Autonomous, no infrastructure needed. • Can be set up anywhere. • Energy constraints • Limited security

ASSOCIATIVE TECHNOLOGIES:

ASSOCIATIVE TECHNOLOGIES IEEE 802.11 Hyper LAN/2

MANET-ARCHITECTURE :

MANET-ARCHITECTURE MANET Node Morphology Fig 3:MANET Node Model

Slide 14:

This architectural model considers MANET nodes as routers with hosts attached as illustrated in figure. These attached hosts may be ”external” or ”internal”. Hosts, and their applications, are not exposed to the specific characteristics of the MANET interfaces. And are connected to the MANET via a router, which has as one or more MANET interfaces .

Slide 15:

ARCHITECTURE(Cont….) MANET Network View Fig 4: MANET Network Model

Slide 16:

This architecture described a configured MANET with routers and hosts, looks as in figure: The inner white cloud represents where MANET interfaces and links form a MANET. The outer gray cloud represents where the classic IP link model is assumed.

MANET CHALLENGES Routing Security and Reliability Quality of Service(QoS) Internetworking Power Consumption

Slide 23:

MANET: ADVANTAGES They provide access to information and services regardless of geographic position. • These networks can be set up at any place and time. • These networks work without any pre-existing infrastructure.

Slide 24:

CONCLUSION MANET is a very simple, reliable and efficient routing protocol for networks. All the nodes dynamically form network Ad hoc networks can be implemented using various techniques like Blue tooth or WLAN for example. The definition itself does not imply any restrictions to the implementing devices.
