To make ad hoc wireless networks adaptive to different mobility and traffic patterns, we studied in this thesis an approach to swap from one protocol to another protocol dynamically, while routing continues. By the insertion of a new layer, we were able to make each node in the ad hoc wireless network notify each other about the protocol swap. To ensure that routing works efficiently after the protocol swap, we initialized the destination routing protocol’s data structures and reused the previous routing information to build the new routing table. We also tested our approach under different network topologies and traffic patterns in static networks to learn whether the swap is fast and whether the swap incurs too much overload . We found that the swap latency is related to the destination protocol and the topology of the network. We also found that the control packet ratio after swap is close to the protocol running without swap, which means our method does not incur too many control packets for swap.
