Fault-Tolerant Routing Strategies in Mobile Wireless Sensor Networks

Mobile wireless sensor networks are crucial in several applications, such as environmental monitoring, disaster management, and military surveillance. Nevertheless, utilizing these devices in remote and hostile settings presents distinct obstacles that can result in node failures and subsequent disruption of community connectivity. Thus, fault tolerance is crucial for guaranteeing the dependability and resilience of MWSNs. This technical brief proposes fault-tolerant routing techniques for Mobile Wireless Sensor Networks (MWSNs) to mitigate the impact of node failures and ensure reliable information delivery. Initially, we develop a distributed clustering algorithm that partitions the network into smaller clusters. Each cluster is led by a selected cluster head responsible for aggregating and transmitting data. During a node failure, the cluster head can redirect and establish a connection with the lower station by utilizing other pathways. In addition, we propose a routing strategy that utilizes mobility to allow nodes to bypass intermediate stations and directly connect to the base station in case of hyperlink failures or unavailability of cluster heads.
