Simulation study of energy efficient scheduling for IEEE 802.15.4/ZigBee cluste...
Jurcik, Petr; Hanzalek, ZdenekThe simulation analysis is important approach to developing and evaluating the systems in terms of development time and cost. This paper demonstrates the application of Time Division Cluster Scheduling (TDCS) tool for the configuration of IEEE 802.15.4/ZigBee beaconenabled cluster-tree WSNs using the simulation analysis, as an illustrative example that confirms the practical applicability of the tool. The simul...
Dimensioning and worst-case analysis of cluster-tree sensor networks
Jurcik, Petr; Severino, Ricardo; Koubâa, Anis; Alves, Mário; Tovar, EduardoModeling the fundamental performance limits of Wireless Sensor Networks (WSNs) is of paramount importance to understand their behavior under the worst-case conditions and to make the appropriate design choices. This is particular relevant for time-sensitive WSN applications, where the timing behavior of the network protocols (message transmission must respect deadlines) impacts on the correct operation of these...
Energy efficient scheduling for cluster-tree wireless sensor networks with time...
Hanzalek, Zdenek; Jurcik, PetrCluster scheduling and collision avoidance are crucial issues in large-scale cluster-tree Wireless Sensor Networks (WSNs). The paper presents a methodology that provides a Time Division Cluster Scheduling (TDCS) mechanism based on the cyclic extension of RCPS/TC (Resource Constrained Project Scheduling with Temporal Constraints) problem for a cluster-tree WSN, assuming bounded communication errors. The objectiv...
On the capacity of cluster-tree ZigBee networks
Jurcik, Petr; Koubâa, Anis; Alves, Mário; Tovar, EduardoModeling the fundamental performance limits of Wireless Sensor Networks (WSNs) is of paramount importance to understand their behavior under worst-case conditions and to make the appropriate design choices. In that direction this paper contributes with an analytical methodology for modeling cluster-tree WSNs where the data sink can either be static or mobile. We assess the validity and pessimism of analytical m...
A simulation model for the IEEE 802.15.4 protocol: delay/throughput evaluation ...
Jurcik, Petr; Koubâa, Anis; Alves, Mário; Tovar, Eduardo; Hanzalek, ZdenekThe IEEE 802.15.4 protocol has the ability to support time-sensitive Wireless Sensor Network (WSN) applications due to the Guaranteed Time Slot (GTS) Medium Access Control mechanism. Recently, several analytical and simulation models of the IEEE 802.15.4 protocol have been proposed. Nevertheless, currently available simulation models for this protocol are both inaccurate and incomplete, and in particular they d...
