Wireless Sensor Network (WSN) uses mobile sinks for web application which provides efficient data accumulation, localized sensor reprogramming, and for distinguishing and revoking compromised sensors. An attacker can easily obtain the key by means of capturing the small fraction of nodes. The sensor network uses existing key for pre-distribution scheme which provides pair-wise key establishment and also for authentication. The employment of mobile sinks for data collection elevates a new security challenge: in the basic probabilistic and q-composite key pre-distribution schemes.
