The wide spread usage of powerful mobile computing devices predict
sizes for future Mobile Ad hoc Networks (MANETs), several magnitudes
larger than current protocols can handle. Our research is targeted
towards providing scalable ad hoc routing and enable conventional
internet services like the DNS, DHCP and SMTP for such MANETs and
eventually seamless integration of wired infrastructure, whenever
available. To this end we have proposed an architecture called Safari
which employs topology aware, hierarchical addressing for the mobile
hosts through a proactive, self-organizing, hierarchical address
assignment protocol. Topology awareness is implemented in a distributed
fashion using a Distributed Hash Table (DHT). Novel to our approach are
beacon broadcasts which are instrumental in creating an adaptive
hierarchy and an overlay structure, and at the same time disseminate
valuable routing information, thus drastically reducing overhead.
