Locally forwarding location management in ad-hoc networks

We consider the problem of mobility management in a hierarchical ad-hoc networks. The examples of such networks range from battlefield to campus networks. We proposed forwarding techniques that are used at the low levels of the hierarchy of the ad hoc networks. In ad hoc networks, the mobile user movement is mainly centralized in the group to which the user belongs. First, we describe the network architecture model of our hybrid hierarchical network and proposed our forwarding scheme. Then we develop an analytical model that is applied to formulate the cost of location update and maintenance of forwarding pointers in this network model. The performance of the forwarding scheme is evaluated through simulation to demonstrate its cost-effectiveness for large ad-hoc networks.
