Underwater Wireless Sensor Networks (UWSNs) are vulnerable to attack because of the broadcast nature of the transmission. The sensor nodes in UWSN are highly constrained in terms of computational capabilities and communication bandwidth. Authentication schemes for ground WSNs might not be applicable for UWSNs due to their less computation and communication capacity. Thus, it is necessary to design...
Wireless sensor network is an important part of the Internet of Things. Preservation of privacy and integrity in wireless sensor networks is extremely urgent and challenging. To address this problem, we propose in this paper an efficient and secure range query protocol in two-tiered wireless sensor networks introducing master nodes. Our proposal not only prevents adversaries from gaining sensitive...
