Simulation of Resource Reservation Protocol in Wireless Networks

1
Simulation of Resource Reservation Protocol in
Wireless Networks

• Enguang He, Min Zhang
• 13 December 1999

2
Motivation

• Support quality of service (QoS) to real time
  application in wireless network.
• RSVP offers very poor performance over wireless
  networks.
• RSVHP was proposed to improve RSVP performance in
  wireless networks.
• How much improvement?

3
Simulation

• Process Oriented Language CSIM is used
• Each cell has a Base Station (BS).
• Each BS serves a number of Mobile Hosts (MH).
• MH can move around cells.
• Handoff happens when MH moves across cells.
