Secure Packet Transfer in Wireless Sensor Networks - A Trust-Based Approach
Trust is very important in wireless sensor networks to transfer the data from source to destination. The Dynamic Source Protocol calculates the alternate path, if any node fails to transfer the data. The Dynamic Source Protocol does not have any built-in functionality to calculate an alternate path if the path has a malicious node. With the expense of an intruder detection system the authors can detect the malicious node and alter the data/packet transfer path. However, intruder detection system is very expensive for wireless sensor networks and there is no guarantee in detecting a malicious node.
