: We propose a novel data collection architecture, called Ring-based Information Collection Architecture (RICA), for sensor networks. In the RICA scheme, sensors are organised into...
Key distribution in Wireless Sensor Networks (WSNs) is challenging. Symmetric cryptosystems can perform it efficiently, but they often do not provide a perfect trade-off between ...

The appliance of wireless sensor networks to a broad variety of applications doubtlessly requires end-user acceptance. End-users from various computer network unrelated disciplines...
Data gathering is a common but critical operation in many applications of wireless sensor networks. The innovative techniques that improve energy efficiency to prolong the network ...
Clustering is an important characteristic of most sensor applications. In this paper we define COSMOS, the Cluster-based, heterOgeneouS MOdel for Sensor networks. The model assum...
