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.

A intuitive demo of RWP can be found here:RWP Demo

Common problems with RWP

  • Zig-zag rajectories.
  • Velocity distribution

Variations

Random Waypoint on the Border(RWPB)

Markovian Waypoint Model(MWP)
