Abstract:
Internet of Things (IoT) and machine-to-machine (M2M) will take root throughout our life in the near future. Therefore more and more reliability is required in many wireless sensor network applications, such as the intruder detection and searching system for main rescuers with some sensor devices. However, without the assumption that all sensor nodes are reachable to one of sink nodes through multi-hop communication and the connectivity among the sensor nodes are stable, it is difficult to guarantee the reliability of data collection. In this paper, we focus on controlling the mobility of the mobile sink and propose two types of mobility strategies to collect the sensing data of all sensor nodes in the observed area certainly. The first strategy is learning the observed area and the other is collecting the sensing data using the learned information. Through computer simulations, we show that the mobile sink with the mobility strategies in our proposal can collect the sensing data of all sensor nodes.
