Event-Based Distributed Filtering of Continuous-Time Nonlinear Systems

A wireless sensor network (WSN) is a distributed communication network containing an array of spatially separated intelligent sensing devices. Although each sensor node is typically small, power-constrained, low-cost, and sometimes unreliable, it can still perform various high-level tasks in a collaborative manner. As a consequence of the rapid development of microprocessors, wireless sensor networks have found a variety of potential applications ranging from environmental monitoring, traffic control, distributed robotics to integrated patient monitoring [1, 2, 3, 4, 5].
