Clustering is an important characteristic of most sensor applications. In this paper we deļ¬ne COSMOS, the Cluster-based, heterOgeneouS MOdel for Sensor networks. The model assum...
We present a sensor network testbed that monitors a hallway. It consists of 120 load sensors and 29 passive infrared sensors (PIRs), connected to 30 wireless sensor nodes. There ar...
Abstract. Achieving optimal battery usage and prolonged network lifetime are two of the most fundamental issues in wireless sensor networks. By exploiting node and data redundancy ...
We propose and evaluate wireless sensor routing algorithms designed to extend the lifetime of a heterogeneous wireless sensor network. The network is heterogeneous in the sensorsā...
An important property in a sensor network is the monitoring of temporal changes of hazardous situations such as forest ļ¬res. Rescue groups need to be aware of dynamic changes th...
