Abstract

In many environmental monitoring applications of Wireless Sensor Networks (WSNs), safe information retrieval from any subset of sensors, at an arbitrary instant of time, should be guaranteed. Accordingly, we study the behavior of a WSN that continuously senses the surrounding environment, while consensus among its nodes is simultaneously enforced. For this running consensus scheme, analytical bounds in terms of consensus degree and comparison with an ideal centralized system are provided, and example of applications are presented.
