2 Presentation Overview Introduction Project Scope & Goal Peer-to-Peer over Ad-hock Network Simulation Scenarios Simulation Result Related Work Conclusion 2

3 Introduction Project Scope QoS of P2P network of wireless nodes in the AODV routing Introducing noise to the network Movement and background traffic Inquiry Packet Interference Single node interference Multiple nodes interference Qos : Quality of Service AODV : Ad-hoc On-Demand Distance Vector 3

4 Peer-to-Peer over Ad-hoc network Peer-to-Peer Architecture All nodes are both client and servers Provide and consume data Any node can initiate a connection No centralized data source The ultimate form of democracy on the Internet The ultimate threat to copy-right protection on the Internet Node Node Node Internet Node Node 4

5 Cont. Benefits Efficient use of resources Scalability: Consumers of resources also donate resources Aggregate resources grow naturally with utilization Reliability Replicas Geographic distribution No single point of failure Ease of administration Nodes self organize No need to deploy servers to satisfy demand Built-in fault tolerance, replication, and load balancing 5

6 Ad-Hoc Network Collection of mobile wireless nodes forming a network without the aid of any infrastructure or centralized administration Nodes have limited transmission range Nodes act as a routers 6

7 Cont. Characteristics Dynamic topologies Limited channel bandwidth Variable capacity links Energy-constrained operation Limited physical security Applications Military battlefield networks Personal Area Networks (PAN) Disaster and rescue operation Peer to peer networks 7

8 Relative Work Peer-to-Peer Ad-hoc Networks: (Re)Configuration Algorithms Marisa A. Vasconcelos, Rainer P. Couto, Antonio A.F. Loureiro Fernanda P.

9 Simulation Scenario To observe the effects of noise on the Quality of Service over a mobile network 3 different scenarios. 9

10 Scenario 1: Two Mobile Nodes Scenario 1 will serve as a reference for Scenario 2 and 3 shows in Figure 5. This simulation tests an Ad-hoc network using the ADOV protocol. 10

11 Scenario 2: AODV Movement Baseline Scenario 2 involves 5 nodes; four nodes are positioned at same distance away from each other and one node moves right to left parallel to other four nodes and then once the node pass all four nodes it moves up and away from the range of all the nodes. 11

12 Scenario 3 This last simulation tests QoS of Ad-hoc network using AODV protocol when the background traffic is introduced. The specific types of data, constant bit rate, and pack drop rate will be compared for analysing the QoS of the network. 12

13 Simulation Results Ongoing Currently analysing baseline scenarios Focus will be on QoS between expected trends and observed trends 13

14 Simulation Scenario 2 : Topology Window Size vs Time 14

15 Future Works Adding Movement and background traffic How the network behave and traffic changes Observe and analysis the changes in the traffic over the network Multiple nodes interference testing How does the Ad-hoc network changes 15
