Multi-metric geo-routing protocol for tactical ad hoc networks

Tactical ad hoc networks equipped with multiple radios have been considered as the basis of future force communication networks envisioned for use in the network-centric warfare paradigm. In this paper, we propose a new geographical routing protocol for such a multi-radio, multi-band tactical ad hoc networking environment. Our protocol is designed to use more than a single routing metric with multiple radio interfaces, each of which runs on different frequency bands. The idea behind the proposed scheme is to choose the right metric and radio for QoS provisioning. Simulation results using the well-known OPNET simulator confirm that the proposed scheme can enhance the routing performance in terms of efficiency and QoS requirement in tactical ad hoc networks.
