  Adapting applications' data rates in multi-hop wireless ad-hoc networks is
inherently challenging. Packet collision, channel contention, and queue buildup
contribute to packet loss but are difficult to manage in conventional TCP/IP
architecture. This work explores a data-centric approach based on Name Data
Networking (NDN) architecture, which is considered more suitable for wireless
ad-hoc networks. We show that the default NDN transport offers better
performance in linear topologies but struggles in more extensive networks due
to high collision and contention caused by excessive Interests from
out-of-order data retrieval and redundant data transmission from improper
Interest lifetime setting as well as in-network caching. To fix these, we use
round-trip hop count to limit Interest rate and Dynamic Interest Lifetime to
minimize the negative effect of improper Interest lifetime. Finally, we analyze
the effect of in-network caching on transport performance and which scenarios
may benefit or suffer from it.
