Wireless sensor and actor networks (WSANs) are characterized by the collective effort of heterogeneous nodes called sensors and actors. Sensor nodes collect information about the physical world, while actor nodes take action decisions and perform appropriate actions upon the environment. The collaborative operation of sensors and actors brings significant advantages over traditional sensing, including...
Severe energy constraints of battery-powered sensor nodes necessitate energy-efficient communication protocols in order to fulfill application objectives of wireless sensor networks (WSN). However, the vast majority of the existing solutions are based on classical layered protocols approach. It is much more resource-efficient to have a unified scheme which melts common protocol layer functionalities...
In this paper, the delay sensitive transport (DST) protocol is presented for wireless sensor networks (WSN). The objective of the DST protocol is to timely and reliably transport event features from the sensor field to the sink with minimum energy consumption. In this regard, the DST protocol simultaneously addresses congestion control and timely event transport reliability objectives in WSN. In addition...
