A Distributed Public Key Caching Scheme in Large Wireless Networks
When asymmetric cryptography techniques are used in wireless networks, the public keys of the nodes need to be widely available and signed by a Certificate Authority (CA). However,...

Maneuverable Relays to Improve Energy Efficiency in Sensor Networks
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...
