Abstract To reduce and optimize energy consumption, many systems perform in-network data aggregation of sensor data at intermediate nodes enroute to the base station (Gateway or G- nodes). Most existing aggregation algorithms and systems do not include any provisions for security, and consequently these systems are vulnerable to a wide range of attacks. In particular, compromised nodes can be used to inject false data that leads to incorrect aggregates being computed at the base station. In this paper, we propose a Fuzzy based Distributed Self-organized Secured G-Cast Routing Protocol (S-GCRP), to identify the most appropriate gateway for efficiently casting data to sink. This approach envisages the principle of Self Organizing Network (SON) for load balancing and distributing routing overheads among G-nodes in the WSN. This approach considers secure routing in wireless sensor networks and presents a robust and secure aggregation protocols that are resilient to false data injection attacks. As such, the proposed protocol accurately analyzes the environment being monitored using only moderate resource consumption. We have implemented the proposed protocol on a network simulator and analyzed its behaviors for a large scale heterogeneous WSN for time critical systems. Simulated results indicate that the new algorithm can build more balanceable clustering structure using SON with enhanced security.
