In this paper, we study the problem of data gathering in multi-hop wireless sensor networks. To tackle the high degree of channel contention and high probability of packet collisi...
Traditional key management techniques, such as public key cryptography or key distribution center (e.g., Kerberos), are often not effective for wireless sensor networks for the se...
—Body Sensor Networks can be used to continuously monitor patients’ health. However, secure association of sensors with the patient and key management for providing integrity a...
With the advance of technology, Public Key Cryptography (PKC) will sooner or later be widely used in wireless sensor networks. Recently, it has been shown that the performance of ...
The term wireless sensor network is applied broadly to a range of significantly different networking environments. On the other hand there exists a substantial body of research on...
