Analysis of Gradient-Based Routing Protocols in Sensor Networks
Abstract. Every physical event results in a natural information gradient in the proximity of the phenomenon. Moreover, many physical phenomena follow the diffusion laws. This natu...

A random perturbation-based scheme for pairwise key establishment in sensor networks
A prerequisite for secure communications between two sensor nodes is that these nodes exclusively share a pairwise key. Although numerous pairwise key establishment (PKE) schemes ...

Attacker traceback with cross-layer monitoring in wireless multi-hop networks
Denial-of-Service (DoS) and Distributed DoS (DDoS) attacks can cause serious problems in wireless networks due to its limited network/host resources. Attacker traceback is a promi...

Iterative Local Solutions for Connected Dominating Set in Ad Hoc Wireless Networks
We propose a general framework of the iterative local solution (ILS) for computing a connected dominating set (CDS) in ad hoc wireless networks, which include wireless sensor netwo...
