Group Mobility Model Based on Mobility Prediction in Tactical Network On-The-Move

In tactical network OTM (on-the-move) environments, tactical nodes should overcome potential disadvantages such as harsh propagation channels and interference, and communication breakdown due to frequent and rapid changes in the network topology without centralized control AP such as immobile base stations as in common wireless networks. In this paper, we propose a group mobility model associated with mobility prediction-based scheme to provide enhanced communication survivability between moving tactical nodes in OTM environments. Using OPNET simulator, the performances of the proposed scheme are evaluated. The simulation results show that the proposed method can provide robust and seamless communication paths between OTM nodes without loss of C2 (Command and Control) information, which are critical to accomplish military operations.
