The paper proceeds to suggest an abstract view of the software robot required to perform the Save Our Souls (SOS) message routing task. It uses a special hierarchical message dispatch system wherein people nearby and more likely to help are contacted. The robot also acts as a proxy to the victim and monitors responses for him.
This paper as a whole gives a cost-effective, high performance system which can be introduced in the market if any of the cellular companies are willing to encourage it.
The system though complete presents a few limitations. They are, the system requires the user to place the cellular phone in a stand or connect the transducer to the vehicle in case of four wheelers. Though this might seem as if taking choice from the user, the fact that the system deals with a question of life or death is more important.
