Mobile sinks play a great role in many wireless sensor network applications for efficient data accumulation, localized sensor reprogramming and for collecting data from various sensor nodes across the globe. However, in sensor networks that make use of the existing three tier security framework, elevates a new security challenge i.e. an attacker can easily create a replicated node and can gain control of the data in the network. Although the three-tier security framework is more resilient to mobile sink replication attacks, it is weak against access point replication attacks. To reduce the damage caused by access node replication attack, strengthening the authentication mechanism between the sensors and access nodes is vital.
