Random Way Point (RWP) Network Model

 

What is RWP

RWP is a commonly used synthetic model for mobility,e.g.,in ad hoc networks.It is an elementary model which describes the movement pattern of independent nodes by simple terms.

Briefly,in the RWP model:

• Each node moves along a zigzag line from one waypoint to another.
• The waypoints are uniformly distributed over the given convex area.
• At the start of each leg a random velocity is drawn from the velocity distribution.(in the basic case the velocity is constant 1)
• Optionally, the nodes may have so-called “thinking times” when they reach each waypoint before continuing on the next leg, where durations are independent and identically distributed random variables.

Common problems with RWP

• Zig-zag rajectories.
• Velocity distribution
