Wireless Sensor Networks (WSNs) have become one of the key technologies for natural environment monitoring. However, replacing nodes may incur negative impact, as a result of damage to nature caused by humans, equipment and vehicles. This paper considers sustainable sensor networks for nature monitoring with low impact on nature by information and communication technologies. To minimize the impact, the authors propose a routing protocol called Less Impact patch Concentration Routing protocol (LICR). In addition, they propose an enhanced version of LICR using energy Harvesting Driven (HD) nodes. The results from the performance evaluation show that LICR and HD-enhanced LICR have less adverse impact on the natural environment.
