Is transience of a protocol shorter, if the mobility simulation is perfect ?

Example: DSR

The mobility model is restricted random-waypoint on Houston section. There are 50 mobiles. At a trip transition instant, if phase is move, numerical speed is drawn at random, uniformly on the interval [0.01,9.99]. Else, if phase is pause, the duration of pause is drawn at random, uniformly on the interval [0,100].

The routing protocol is DSR. There are 20 data connections, each with a fixed packet send rate of 1 pkt/sec. Packet lengths are fixed to 512 B.

Default initilization rule : for each mobile, t=0 is a trip transition instant. Initially, each mobile is in move phase.

Results with no paussing are similar: see S. PalChaudhuri et al.

Numerical speed

The left plot shows numerical speed averaged over all mobiles at time instants spanning [0,5000]. The right plots show histograms of mobile speeds at time 1, 100, 1000, and 5000 seconds since the simulation start.


Packet delivery ratio

The plots show packet delivery ratio defined as (# received packets) / (# transmitted packets), which is computed over 10-second intervals, averaged over all data connections and averaged over 100 simulation runs.
With default initilization rule
With perfect mobility simulation
Check the hypothesis: perfect simulation of mobility induces shorter transience for a protocol, than with default initilization rule.
