Publication Abstract

The wide proliferation of WSNs in various domains has lead to the emergence of numerous applications having all different requirements. Consequently, different approaches and communications protocols have to be developed to meet these diverse and specific requirements. Moreover, network lifetime, as a major constraint of WSN, should be considered in the design of protocols for such networks. To this end, duty cycling technique is almost adopted. In applications susceptible to the time, it is hard to meet short delay delivery for real time traffic in duty cycled networks since nodes are not always awake. In this context, we propose nodes disjoint routes establishment from sources of critical traffic toward the sink. Our protocol aims to offer always at least one available path while keeping nodes operating with duty cycling protocol in order to satisfy the requirements needed for real time applications.
