This work presents a class of unidirectional lifting-based wavelet transforms for an arbitrary communication graph in a wireless sensor network. These transforms are unidirectiona...
We develop energy-efficient, adaptive distributed transforms for data gathering in wireless sensor networks. In particular, we consider a class of unidirectional transforms that ...
Abstract—Time synchronization is a key component in numerous wireless sensor network applications. Most of the current software based time synchronization approaches suffer from ...
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...
