Abstract

Key pre-distribution in wireless sensor and actor network (WSAN) is a challenging problem because the key pre-distribution schemes in wireless sensor network (WSN) are not well-suited for the unique features and requirements. In this paper, a new scheme of key pre-distribution in WSAN (RTKPS) is presented. To achieve the distributed and integrated secure communication scheme, the paper describes a construction of the key management tree among sink, actors, and sensors by making use of the sufficient energy capabilities, larger memory, better processing and communication capabilities of actor nodes. The analysis and simulation show that the proposed scheme can effectively save memory space and evidently improve security.
