Interworking of tactical ad hoc and static IP-network

In this report we investigate the relationship between host/network mobility and mobility within an ad hoc network to support seamless connectivity between a fixed core network infrastructure and an autonomous mobile tactical ad hoc network. There are several command and control systems within the Swedish defence to guide warfare operations and military efforts. By integrating these in the network centric warfare system, higher efficiency and information dominance can be achieved. Mobile ad hoc network designs provide means for members to join and leave particular radio frequency subsystems as their position changes. The problem is that that the nodes (or sub-networks) should always be addressed with the same IP-address to be reachable. In this report we assume the protocol Mobile IPv6 to be used when meeting the goals of this integrated architecture. Five tactical scenarios have been studied analytically and the problems and the effects on the network layer have been defined when the ad hoc network have been moving and changing access points to the fixed network. The conclusions were that using Mobile IPv6 together with Ad hoc On Demand Vector routing protocol is not enough to manage the access network in a tactical scenario. In this report we introduce a mobility management model that can provide seamless traffic management and connectivity to host applications in the network centric warfare system.
