Wireless Sensor and Actor Networks (WSANs) are composed of a large number of heterogeneous nodes called <i>sensors</i> and <i>actors</i>. The collaborative operation of sensors enables the <i>distributed sensing</i> of a physical phenomenon, while the role of actors is to collect and process sensor data and perform appropriate actions.In this paper, a(More)
In this paper, coordination and communication problems in wireless sensor and actor networks (WSANs) are jointly addressed in a unifying framework. A sensor-actor coordination model is proposed based on an event-driven partitioning paradigm. Sensors are partitioned into different sets, and each set is constituted by a data-delivery tree associated with a(More)
Since sensor networks can be composed of a very large number of nodes, the developed protocols for these networks must be scalable. Moreover, these protocols must be designed to prolong the battery lifetime of the nodes. Typical existing routing techniques for ad hoc networks are known not to scale well. On the other hand, the so-called geographical routing(More)
In this paper, UW-MAC, a distributed Medium Access Control (MAC) protocol tailored for UnderWater Acoustic Sensor Networks (UW-ASNs), is proposed. It is a transmitter-based Code Division Multiple Access (CDMA) scheme that incorporates a novel closed-loop distributed algorithm to set the optimal transmit power and code length. UW-MAC aims at achieving three(More)
