In this paper, we present and visit the limitation of reference point group mobility model. It assumes that nodes
in the same group always stay together throughout the simulation process. However, in many real life
applications, the nodes’s movement within a group is not always common. In particular, in a military operation,
initially there is only one group. With multiple missions assigned to it, the group may be divided into a number
of subgroups with each subgroup moving to a different location for accomplishing its task. A subgroup may be
further divided into smaller groups or merge with other subgroups after completing its task. Therefore, in many
scenarios it is necessary for a group to partition itself into smaller groups or a number of smaller groups to merge.
Some recent researches present mobility models, which model possible group partitioning and group merging.
We call this kind of mobility model a reference region group mobility model for ad hoc networks.
Keywords: Group, partition, Merging, MANET, review.
Node mobility is one of the inherent
characteristics of mobile ad hoc networks (MANET).
It is also one of the parameters that most critically
affect the performance of network protocols (e.g.,
routing). Today, in most simulation experiments,
node movement is modeled as an independent
random walk. One such model is the Random
WayPoint mobility (RWP) model, which is the most
popular mobility model used in the literature .
However, in real military scenarios, node mobility is
not always independent. Mobili
