—Duty-cycle MAC protocols have been proposed to meet the demanding energy requirements of wireless sensor networks. Although existing duty-cycle MAC protocols such as S-MAC are p...
This paper proposes a policy-based management framework for self-managed wireless sensor networks (WSNs) called SNOWMAN (SeNsOr netWork MANagement). In WSNs, a number of sensor nod...
—Nonparametric belief propagation (NBP) is one of the best-known methods for cooperative localization in sensor networks. It is capable to provide information about location esti...
The protocol design for wireless roaming authentication is challenging because of the key management regarding users and home/visited networks. In this paper, we present two authe...
