Discrete-event simulation modeling tool for routing process in GPSR ad hoc network routing protocol

Modeling and simulation are traditional methods used to evaluate wireless network design, this paper provides a discrete event simulation modeling tool built using Borland c++ builder 6 to modeling a GPSR protocol routing process in ad hoc wireless network, this paper describe the main components of discrete event simulation tool used in building any discrete event simulation model such as processes, activities, events, it can also help other researchers to build their own simulation tool.
