Reliable GPS-Free Double-Ruling-Based Information Brokerage in Wireless Sensor Networks
Abstract—Because the global positioning system (GPS) consumes a large amount of power and does not work indoors, many GPS-free information brokerage schemes are proposed for wire...

Efficient online/offline identity-based signature for wireless sensor network
In this paper, we present an online/offline identity-based signature scheme for the wireless sensor network (WSN). We argue that due to significant reduction in costs of computati...

Time-based localization for asynchronous wireless sensor networks
In this paper, we propose time-based localization approaches for asynchronous wireless sensor networks (WSNs), where not only clock skews but also clock offsets are present at all...
