Sensors have a function to gather environmental data in sensor networks. They operate by limited, small-size battery depending on applications. Thus there are several kinds of research efforts to make better use of local energy. In this paper, we propose multi-attribute query processing algorithm (Section Bit based scheme (SB)). In the initial setup, routing path is determined based on parent-child relationship by two phases and some partial information (section bits) about the sensing data of their descendant nodes are delivered to the parent in second phase (parent selection phase); that is, an attribute is divided into the same, small size, N sections and one bit is used to each section. By using a small volume of local information, it is possible to protect nodes from propagating messages who does not become the help during query processing. Finally, we measure energy efficiency by counting the number of messages. Experimental results show the improved energy efficiency of the proposed algorithm.
