Abstract
Data gathering is a key problem in Wireless Sensor Network(WSN), the current tree-based data gathering methods often result in some problems, such as the load imbalance, the uncontrolled height of the tree, the larger delay of data gathering and so on. To solve this problem, this paper proposes a new algorithm DSDA((Delay Bounded Data Gathering). The algorithm constructs a Fewest Hops Tree(FHT). It iteratively adds an edge to the tree, and it satisfies with user's requirement for delay by limiting tree's height, and it can extend the tree lifetime by making the degree of nodes in the tree which is decreased to the minimum. Simulation results show that the algorithm can construct a tree under limited tree's height, which has longer lifetime than previous protocols.
