GOALS AND DEFINE THE SYATEM.1

2NETWORK MODELING AND SIMULATION.

•An autonomous system in which nodes connected by wireless links are free to move randomly and often behave as routers simultaneously.

1.1. DEFINE THE SYSTEM OF AD-HOC NETWORK.

The topology of such the networks changes frequently.

GOALS AND DEFINE THE SYSTEM

NETWORK MODELING AND SIMULATION.

•Routing is a challenging task in Ad-hoc network.

1.1. DEFINE THE SYSTEM OF AD-HOC NETWORK.

•Typical Ad-hoc routing protocols:

Dynamic Source Routing (DSR). Ad-hoc On-Demand Distance Vector

Routing (AODV).Destination-Sequenced Distance-

Vector (DSDV).…

GOALS AND DEFINE THE SYSTEM

1.1. MARJOR GOALS OF MINI-PROJECT.

5NETWORK MODELING AND SIMULATION.

Compare the efficiency between DSDV and AODV, known as novel approaches in proactive and reactive, respectively, in terms of end-to-

end delay and throughput based on given scenarios.

2.1. OUTCOMES.

8NETWORK MODELING AND SIMULATION.

•The successfully receiving the packets.

LIST OF SERVICES AND OUTCOMES

SIMULATION METRICS.3

9NETWORK MODELING AND SIMULATION.

The rate of transfer data from a source to a destination during specific time.

A higher throughput will directly impact the user’s perception of the quality of service (QoS).

THROUGHPUT.

All possible delays caused by buffering route discovery latency, queueing and interface queue, retransmission delays at the MAC, and propagation and transfer times of data packets.

AVERAGE END-TO-END DELAY.
