The most modern tactical communication systems employed today in the battlefield are IP-based mobile ad hoc networks. Its goal is to integrate communications from different platforms and different forces in a hostile environment without last mile infrastructure installed. It supports modern warfare doctrines like network-centric warfare and information superiority. However, such solutions use technologies that are not suited for war scenarios, as they employ host-centric protocols (IP). This leads to inefficiency in the dissemination of information, increase in complexity, latency and bandwidth. In combat, links are intermittent, narrow-band, with intentional interference, where communication is group-centered (what you see and hear must be shared among all to form what is known as situational awareness). The project aims to develop a group-centric network protocol stack, a technology more suited for decentralized, disruptive environment with specific quality of service policies for tactical operation in order to meet strict performance requirements imposed by mission critical situational awareness applications, increasing the availability and quality of information and thus reducing the operational delay in decision making.
