In order to monitor the leakage of hazardous chemicals and guarantee the safety of people in hazardous areas, we developed RESRS (Robot Emergency Search and Rescue System). RESRS integrated technologies such as mobile robot and WSN (Wireless Sensor Network). The mobile robots in the system act as mobile nodes of WSN. We describe the components of the generic RESRS's architecture in detail. A small-scale...
This paper proposes a framework to maximize the lifetime of the wireless sensor networks (WSNs) by using a mobile sink when the underlying applications tolerate delayed information delivery to the sink. Within a prescribed delay tolerance level, each node does not need to send the data immediately as it becomes available. Instead, the node can store the data temporarily and transmit it when the mobile...
As sensor technology advances, the availability of high resolution data and complex sensor readings become more commonplace, and the range of potential sensor network applications, accuracy, and data collection efforts expands. As a result, there is an increased need for tiered sensor network architectures and energy efficient data collection mechanisms in order to maintain network feasibility and...
