Unlike in terrestrial sensor networks where the locations of destination nodes are often assumed to be fixed and accurately known, such assumptions are usually not valid in under...
This paper presents an efficient technique for placement and routing of sensors/actuators and processing units in a grid network. Our system requires an extremely high level of ro...
Wireless sensor networks (WSNs) are commonly used for continuously monitoring applications. This paper investigates a base station assisted energy efficient routing for hierarchi...
We present our experience with designing, developing, and deploying of an Internet accessible wireless sensor network for monitoring temperature, humidity, and illumination of a c...
Security of sensor grids is important especially for surveillance, military and medical applications. The paper addresses methods for two security features. First, an approach for ...
