Pursue mobility model
Encyclopedia
The pursue mobility model is a type of mobility model
which is used in ad hoc wireless network
s. It is also based on RPGM (reference point
group model). The Pursue Mobility Model simulates scenarios where several nodes attempt to capture single mobile node ahead. This mobility model could be used in target tracking and law enforcement. The node being pursued (i.e., target node) moves freely according to the Random waypoint model
. By directing the velocity towards the position of the targeted node, the pursuer nodes (i.e., seeker nodes) try to intercept the target node.
The Pursue Mobility Model consists of a single update equation for the new position of each Moving Node: new position = old position + acceleration(target—old position) + randomvector.
Example: Nodes chase after a single target that may or may not be moving. Here we have a collection of robots (nodes) trying to catch a single robot that acts as a target. This kind of behavior is found in multiple robotics activities (e.g.: people tracking and so on).
Mobility model
Mobility models represent the movement of mobile users, and how their location, velocity and acceleration change over time. Such models are frequently used for simulation purposes when new communication or navigation techniques are investigated...

Reference Point is the first album by Acoustic Alchemy released in 1990 for jazz label GRP and their fourth album overall.Containing some of the band's more popular tracks, such as the title track "Reference Point", "Same Road, Same Reason" and "Cuban Heels", the nine-track album is also the only...

Random waypoint model
The Random waypoint model is a random-based mobility model used in mobility management schemes for mobile communication systems. The mobility model is designed to describe the movement pattern of mobile users, and how their location, velocity and acceleration change over time...
