—In wireless sensor networks, sensor nodes are expected to gather specific information about the environment and send it to the user. The data dissemination usually involves many...
Abstract. This paper proposes an efficient resource-optimal key predistribution scheme for providing improved security in wireless sensor networks. We exploit the advantages of two...
This paper presents a novel method for optimizing sliding window based continuous queries. We deal with two categories of aggregation operations: stepwise aggregation (e.g. COUNT) ...
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...
