In-Network Historical Data Storage and Query Processing Based on Distributed Indexing Techniques in Wireless Sensor Networks
نویسندگان
چکیده
Most of existing data processing approaches of wireless sensor networks are real-time. However, historical data of wireless sensor networks are also significant for various applications. No previous study has specifically addressed distributed historical data query processing. In this paper, we propose an Index based Historical Data Query Processing scheme which stores historical data locally and processes queries energyefficiently by using a distributed index tree. The simulation study shows that our scheme achieves good performance on both query responding delay and network traffic.

Random Key Pre-Distribution Techniques against Sybil Attacks
Sybil attacks pose a serious threat for Wireless Sensor Networks (WSN) security. They can create problems in routing, voting schemes, decision making, distributed storage and sensor re-programming. In a Sybil attack, the attacker masquerades as multiple sensor identities that are actually controlled by one or a few existing attacker nodes. Sybil identities are fabricated out of stolen keys, obt...
