Abstract

Key predistribution in wireless sensor and actor network WSAN is a challenging problem because the key predistribution schemes in wireless sensor network WSN are not wellsuited for the unique features and requirements In this paper a new scheme of key predistribution 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
