hi all
did anyone know how can i get DSR code for Broch et. al., or how can i modify
the tcl script attached according to the following simulation parameters to get
high packet delievery ratio, around 0.8 to 0.98
the simulation parameters:
* simulations are for networks of 50, 112, and 200 nodes with 802.11
WaveLAN radios, with a nominal 250-meter range.We simulate 30 CBR traffic
flows, originated by 22 sending nodes. Each CBR flow sends atEach simulation
lasts for 900 seconds of simulated time.
* The nodes are initially placed uniformly at random in a rectangular
region. All nodes move according to the random waypoint model, with a maximum
velocity of 20 m/s.
* We simulate pause times of 0, 30, 60, and 120 seconds, the highest
mobility cases,
*
* 2 Kbps, and uses 64-byte packets.
*
* We simulate at each pause time with six different randomly generated
motion patterns, and present the mean of each metric over these six runs.
thanks alot
