ABSTRACT: The growing
demand of usage of wireless sensors applications in different aspects makes the
quality-of-service (QoS) to be one of paramount issues in wireless sensors
applications. Quality of service guarantee in wireless sensor networks (WSNs)
is difficult and more challenging due to the fact that the resources available
of sensors and the various applications running over these networks have
different constraints in their nature and requirements. Traditionally quality of service was focused on network
level with concern in metrics such as delay, throughput, jitter e.c.t. In this
paper we present appropriate metrics of QoS for WSN which involve service, reliability and availability which ultimately
facilitating in archiving qualitable service. We discuss the reverse look of
QoS and hence present mathematically the three significant quality factors that
should currently be taken into account in developing WSNs application quality
services namely, availability, reliability and serviceability. We run
experiments incorporating these three phenomenons (reliability, availability and
serviceability—RAS) to demonstrate how to attain QoS which effectively improve
reliability of the overall WSNs.
