In wireless sensor networks (WSNs), sensors' locations play a critical role in many applications. Having a GPS receiver on every sensor node is costly. In the past, a number ...
Abstract Several applications have been proposed for Wireless sensor networks, including habitat monitoring, structural health monitoring, pipeline monitoring, precision agricultur...
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,...
A Wireless Sensor Network (WSN) composed of tiny sensor nodes may operate in an unfavorable terrain. The coupling of inherent limitations and harsh environments makes WSNs fallible...
