This model represents a set of Mobile Nodes that move around a given line (or column), which is moving in a forward direction. In this paper we propose a modified column mobility model. A slight modification of the Column Mobility Model allows the individual Mobile Nodes to follow one another and search any node randomly in a column in an efficient manner.

This model represents a set of Mobile Nodes that move around a given line (or column), which is moving in a forward direction. A slight modification of the Column Mobility Model allows the individual Mobile Nodes to follow one another.
