Cross-layer analyses of QoS parameters in wireless sensor networks

Abstract

Providing reliable and timely information is one of the important tasks of wireless sensor networks. To this end, recently quality of service (QoS) satisfying end users and matching WSN constrains, has become an important research topic. However, majority of research in this area has overlooked the fact that ensuring quality of service requires a cross-layer approach spanning through all layers of the protocol stack. In this paper, we study QoS parameters and requirements in WSNs in application, data management and physical levels and analyze their cross-layer effects using simulations. © Springer-Verlag Berlin Heidelberg 2011.
