Key Design / Approach DSR(basic, optimized, multipath), AODV,

and TORA protocols implemented–Node Resident Service functions for basic

protocol operations (coded in Popcorn)–Protocols (really mobile glue code)

implemented in PLAN Dynamic Linking of protocol modules Limitation:

–Due to lack of concurrency in FASTNet, only Route Discovery protocol is implemented. Route Maintenance is emulated.

New Ideas

Dynamic Ad Hoc Routing Protocols implemented in an active networking test-bed

Dynamic Protocol Dissemination using mobile code

Provides Increased adaptability to unpredictable Ad Hoc environment

Active Ad Hoc Networking

Results / Lessons Learned Implemented in FASTNet & PLAN (Linux) Choose routing protocols adaptively. Lessons learned:

–AN can provide dynamic & efficient routing protocols for MANET

–Decision-making mechanism for optimal protocol in each environment is needed

–Need to extend this idea in test-bed system
