【Abstract】 Two new concepts as subnet and energy-core were proposed,and an innovative ant algorithm was designed.Besides,a distributed data-centric hierarchical ant routing algorithm for sensor networks,which is based on subnet and named DDCHA was proposed. Compared with previous centralized algorithms such as AC and GITDC,the proposed algorithm is distributed and requires local location information only.Additionally,the positive feedback ability of ant algorithm and the construction of subnets and energy-core can improve the degree of data aggregation,and reduce the time complexity of the proposed algorithm at the same time.Both theoretical analysis and experiment results show that the algorithm is effective.更多还原
