muDog: Smart Monitoring Mechanism for Wireless Sensor Networks Based on IEEE 802.15.4 MAC
The resources in Wireless Sensor Networks (WSNs) are limited like energy and bandwidth which motivate nodes to reduce their energy consumption and increase their bandwidth. There are two main ways to optimize the network resources: a honest way and a malicious way. The malicious way is attractive, because it enables nodes to significantly reduce their energy consumption and increase their bandwidth with a simple and easy node reprogramming. Furthermore, detect these malicious nodes is a real challenge which is mainly due to WSNs characteristics. However, the existing monitoring mechanisms like Watchdog are not adapted to WSNs characteristics.
