We propose a hybrid model to alleviate the notorious problem of premature battery depletion in sensor networks: in a first stage, simple sensors are deployed over an area of inter...
Wireless Sensor Network (WSN) deployed in hostile environments suffers from severe security threats. In this paper, we propose a Secure Message Percolation (SMP) scheme for WSN. We...
Sensor networks are composed of a large number of low power sensor devices. For secure communication among sensors, secret keys must be established between them. The establishment...
— We address the problem of secure location determination, known as Secure Localization, and the problem of verifying the location claim of a node, known as Location Verificatio...
We study the problem of mining frequent value sets from a large sensor network. We discuss how sensor stream data could be represented that facilitates efficient online mining and ...
