Assessment Title

Analysis of routing protocols in terms of security, QoS, and energy efficiency

Purpose of the assessment (with ULO Mapping)

The purpose of the assignment is to analyse the routing protocols and evaluate them in terms of security, QoS, and energy efficiency. Students will be able to complete the following ULOs: a. Compare standards-based technologies used in various networks; b. Test and evaluate various wireless networks performance;

Assignment Description

Part A Mobile Ad Hoc network (MANET) is a collection of mobile devices which form a communication network. There are multiple type of routing protocols designed for MANETs such as Ad Hoc OnDemand Distance Vector (AODV), Destination-Sequenced Distance-Vector (DSDV), Dynamic Source Routing (DSR) and Ad Hoc On-Demand Multipath Distance (AOMDV). Students are required to submit a report including technical details on Dynamic Source Routing (DSR) and Ad Hoc On-Demand Multipath Distance (AOMDV) protocols. Report must include details on

• Routing mechanism

• Advantages and limitations of using these protocols in WSNs

Part B Wireless networks performance varies from wired networks, the latter uses a guided medium and wireless networks use unguided medium for transmission. To design and simulate wireless networks the network simulator - 2 (NS - 2), an open source discreet event simulator could be used. The NS-2 simulator is a widely used simulation tool, which could generate trace files for analysis and comes with a network animator to visualize the network performance.

The students are required to: Design a wireless network consisting of 15 nodes; the dimensions for the given topology are 250x250. The agent type should be UDP and the traffic CBR. The simulation should run for 300 seconds. Random deployment of nodes is required and the nodes are required to transmit packets over the network. The wireless node configuration should include the NS-2 energy model. Run the simulation on routing protocol DSR or AOMDV. Critically analyse the trace files in terms of packets sent, received and dropped. These parameters should be plotted on graphs and discussed in detail. Include screenshots of the NAM displaying the nodes deployed during the simulation and add screen shots of the simulation. Appendix I should include the tcl srcript used in each simulation.
