Traditional approaches for wireless sensor network diagnosis are mainly sink-based. They actively collect global evidences from… Expand Energy-efficient and reliable transmission of sensory information is a key problem in wireless sensor networks. To save more… Expand In mobile agent based data fusion, the order of nodes visited along the route by mobile agent has a significant impact on the… Expand This paper establishes a distributed data fusion method for ad hoc networks, enabling each device or agent to operate… Expand Addressing a question of Fredman and Willard from STOC'90, we show that fusion trees cannot be implemented using the AC<sup>0… Expand This article illustrates several examples of computer science problems whose performance can be improved with the use of either… Expand We define two conditions on a random access machine (RAM) with arithmetic and Boolean instructions and possible bounds on word… Expand Abstract This paper introduces a new sublogarithmic data structure for searching, the fusion tree. These trees lead to improved… Expand a related loglogN improvement of Chazelle’s O(N logd-lN / log log N) space data structure [C86a], that performs the reporting… Expand The fusion tree method is extended to develop a linear-time algorithm for the minimum spanning tree problem and an O(m+n log n… Expand
