“…Query routing technique is undoubtedly one of the most typical routing protocols for wireless sensor networks (WSNs) [1], which is concretely composed by interest message diffusion, data transmission, and path enhancement in the implementation process [2][3][4][5]. The routing method has several remarkable highlights in data-oriented monitoring applications, such as direct transmission of interested data, information screening [6], and local communication [7], resulting in the advantages of less redundant information and long network lifetime.…”

Although some progress has been made in studying the triggering updating methods of interest message for reducing node energy consumption in directed diffusion routing protocols, they do not consider the anisotropy of sensing areas of nodes and the requirement of diversity of interest message exchange rates within real-time performance, which makes these studies unable to accurately adapt to the characteristics of interest message update. In this work, we proposed an improved triggering updating method (ITUM) consisted of adaptive threshold determination based on the analytic hierarchy process and update judgement by similarity comparison of interest messages. Meanwhile, the network model and the sensing model are presented to describe actual network scenarios. We analyze the impact of critical parameters and evaluate the performance of ITUM with several interest message updating methods from the aspect of lowering the number of information exchanges. The simulation results prove that ITUM can improve the adaptability to scene changes while decreasing the number of information exchanges compared with the existing methods. Furthermore, it is shown that ITUM is a highly effective solution for determining the triggering updating conditions of various information exchange rates in directed diffusion routing protocol.
