Abstract

Many sensor network systems encounter considerable problems after deployment despite extensive simulation and testing during the development. A fundamental issue is unforeseen problems that rarely occur, which makes them hard to reproduce. This work focuses on a class of problems that occur due to so-called software aging: The classical software engineering approach to handle software aging effects is software rejuvenation, i. e., the proactive reset of software components. In this positioning paper we discuss whether software rejuvenation can be applied to resource scarce sensor nodes, which are tightly coupled distributed system. We detail why and how software rejuvenation techniques are applicable to sensor networks and presents the basic building blocks required.
