  In Wireless sensor networks, sensor nodes sense the data from environment
according to its functionality and forwards to its base station. This process
is called Data collection. The Data collection process is done either directly
or by multi-hop routing. In direct routing, every sensor node directly
transfers its sensed data to base station which has an impact on energy
consumption from sensor node due to the far distance between the sensor node
and base station. In multi-hop routing, the sensed data is relayed through
multiple nodes to the base station, it consumes less energy. This paper
presents and analyzes the performance of a data collection routing protocol
called RFDMRP: River Formation Dynamics based multi-hop routing protocol. The
performance of RFDMRP is tested and analyzed for network parameters such as
Network lifetime, Energy usage, and Node density & data aggregation impact on
network lifetime. The simulated results are compared with two algorithms LEACH
and MOD_LEACH. The comparison reveals that the proposed algorithm performs
better than LEACH and MOD_LEACH with respect to Network lifetime.
