A Randomized Countermeasure Against Parasitic Adversaries in Wireless Sensor Networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Jun Luo

Due to their limited capabilities, wireless sensor nodes are subject to physical attacks that are hard to defend against. In this paper, we first identify a typical attacker, called parasitic adversary, who seeks to exploit sensor networks by obtaining mea ...

Design and implementation of an efficient data stream processing system

Ali Salehi

In standard database scenarios, an end-user assumes that all data (e.g., sensor readings) is stored in a database. Therefore, one can simply submit any arbitrary complex processing in the form of SQL queries or stored procedures to a database server. Data ...
