In order to reduce the complexity of the access to heterogeneous sensor network data.This paper presents the design of a wireless sensor network middleware by studying a heterogeneous network of wireless sensor network access technology.The program is based S3C6410-based embedded processor development board as hardware development platform.WSN gateway and the Adhoc gateway formed the Adhoc type of network by AODV routing protocol.Thus solve the problem of wireless sensor networks with the outside public network connection.The program achieves wireless sensor network data upload to a remote server.While providing a reliable solution for a number of sensor networks at the same time access the external network.
