Wireless Sensor and Actor Networks (WSAN) are composed of large number of sensor nodes collaboratively observing a physical phenomenon and relatively smaller number of actor nodes, which act upon the sensed phenomenon. Due to the limited capacity of shared wireless medium and memory restrictions of the sensor nodes, channel contention and network congestion can be experienced during the operation of the network. In fact, the multi-hop nature of WSAN entangles the level of local contention and the experienced network congestion. Therefore, the unique characteristics of WSAN necessitate a comprehensive analysis of the network congestion and contention under various network conditions. In this paper, we comprehensively investigate the interactions between contention resolution and congestion control mechanisms as well as the physical layer effects in WSAN. An extensive set of simulations are performed in order to quantify the impacts of several network parameters on the overall network performance. The results of our analysis reveal that the interdependency between network parameters call for adaptive cross-layer mechanisms for efficient data delivery in WSAN.

A real-time and reliable transport (RT)(2) protocol for wireless sensor and actor networks Gungor, Vehbi Cagri; Khan, Oezguer B.; Akyildiz, Ian F. (2008-04-01) Wireless Sensor and Actor Networks (WSANs) are characterized by the collective effort of heterogenous 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 improved accuracy, larger coverage area and timely actions upon the sensed phenomena. However, to realize th...
Real-time coordination and routing in wireless sensor and actor networks Shah, Ghalib A.; Bozyigit, Muslim; Akan, Ozgur B.; Baykal, Buyurman (2006-01-01) In Wireless Sensor Actor Networks (WSAN), sensor nodes perform the sensing task and actor nodes take action based on the sensed phenomena in the field. To ensure efficient and accurate operations of WSAN, new communication protocols are imperative to provide sensoractor coordination in order to achieve energy-efficient and reliable communication. Moreover, the protocols must honor the application-specific real-time delay bounds for the effectiveness of the actors in WSAN.
Cluster-based coordination and routing framework for wireless sensor and actor networks Shah, Ghalib A.; Bozyigit, Muslim; Hussain, Faisal B. (2011-08-01) In Wireless Sensor Actor Networks (WSAN), sensor nodes perform the sensing task and actor nodes take action based on the sensed phenomena. Generally, the network is configured to observe multiple events and to react upon each individual event accordingly. Time delay, energy efficiency and reliability are three important aspects of WSAN that require special attention. To ensure efficient and reliable operations of such heterogeneous WSAN, new communication protocols are imperative.
On event signal reconstruction in wireless sensor networks Atakan, Baris; Akan, Oezguer B. (2007-05-18) In Wireless Sensor Networks (WSN), the effective detection and reconstruction of the event signal is mainly based on the regulation of sampling and communication parameters used by the sensor nodes. The aim of this paper is to understand the effect of these parameters on the reconstruction performance of event signal in WSN. Theoretical analysis and results show that with proper selection of sampling and communication parameters, the event signal can be satisfactorily reconstructed at the sink. Furthermore,...
Spatio-temporal Characteristics of Point and Field Sources in Wireless Sensor Networks Vuran, Mehmet C.; Akan, Ozgur B. (2006-06-15) Wireless Sensor Networks (WSN) are comprised of densely deployed sensor nodes collaboratively observing and communicating extracted information about a physical phenomenon. Dense deployment of sensor nodes makes the sensor observations highly correlated in the space domain. In addition, consecutive samples obtained by a sensor node are also temporally correlated for the applications involving the observation of the variation of a physical phenomenon. Based on the physical characteristics and dispersion patt...
