The main purpose of this research is to discuss scenarios when some common dynamic changes happen to Wireless Sensor Networks/Autonomous Networked Robots, what the negative effect will be, along with our proposed strategies to keep networks resilient to such influence because communication between sensors/robots is fundamental to cooperation, hence the central role of the network. The first part of this dissertation considers scenarios where dynamic changes happen to static wireless sensor network, causing sensors in some sub-areas to not function anymore. Our work explores two resilient routing strategies to maintain communication links between any two sensors under such situations. Further, the second part of this dissertation brings mobility into wireless sensor networks. Specifically, we consider a more complex scenario where a group of Autonomous Networked Robots are given orders to march from a current field of interest to new one. And our work explores a resilient redeployment strategy that tries to keeps original communication links as many as possible. The dynamic changes and network models in this research are very common in reality; therefore, this research has much practical significance.
