reason for packet drop may arise due to congestion,
faulty hardware and queue overflow etc.
3. Time taken for simulation:-This criterion specifies
the total time taken by NCTUns-6.0 simulator to
simulate individual scenario cases with separate routing
protocols.
4.3. Simulation Scenario
Four cases are considered for highway and city
scenarios with variable number of nodes (vehicles) and
variable speeds. These scenarios are drawn using
NCTUns-6.0 “draw topology” feature.
Case #1:
Figure 7: City Scenario Case with 50 nodes and 8 m/s
speed drawn using NCTUns-6.0
4.4. Simulation Setup
In this simulation study following network
parameters and tools are selected:
1. IEEE 802.11b (ad-hoc mode) standard is used for
each vehicular node.
2. 1400 bytes of UDP packets used for
communication.
3. 15dbm Transmission power used for node
operation.
Table 1 and 2 specifies the parameter settings for
both highway and city scenarios respectively.
