OCSR: Overlapped Cluster-Based Scalable Routing Approach for Vehicular Ad Hoc Networks (VANETs)

Algorithm 5

Mobility Management.

Input: G, V

1. If vehicle V moves within cluster

2.  Broadcast changes to vehicles in same cluster

3.  Vehicles update their HR

4. Else if vehicle V moves from one cluster to another

5.  Update MR maintained by new SN (V)

6.  Update MR maintained by previous SN (V)

7.  No update required in HR

8. Else

9.  No movement, no update is required

10. End if
