摘要

Accessing information remotely to dynamically changing information elements cannot be avoided and has become a required functionality for various network services. Most applications require up-to-date information which is reliable and accurate. The information reliability in terms of using correct information is challenged by dynamic nature of information elements. These challenges are more prominent in case of wireless sensor network (WSN) applications, as the information that the sensor node collects are mostly dynamic in nature (say, temperature). Therefore, it is likely that there can be a mismatch of information between the one which user uses and the one which is available at the source at the same instant of time. This leads to unreliable information being used by the application user for processing. Information accessing with minimal mismatch is desired by the WSN applications especially when WSN is used for safety and security monitoring purposes. In this paper, we evaluate different access strategies to remote dynamic information and compare between achieving information reliability (mismatch probability) and the associated power consumption. Lastly, based on the models, we propose an adaptive information access mechanism and show how trade-off between energy consumption and information reliability can be achieved.
