—We investigate the following fundamental question—how fast can information be collected from a wireless sensor network organized as tree? To address this, we explore and evalu...
Sensor networks are widely used in monitoring and tracking a large number of objects. Without prior knowledge on the dynamics of object distribution, their density estimation could...
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...
We propose a game-theory-based cross-layer optimization scheme for wireless Direct Sequence Code Division Multiple Access (DSCDMA) visual sensor networks. The scheme uses the Nash...
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...
