Information Security Wireless Sensor Grid

The combination of the wireless sensor network (WSN) and grid computing in wireless sensor grid (WSG) architecture enables the strengths and characteristics of wireless sensor network and grid computing to be realized on a single integrated platform. This paper analyzes the necessity and key problems of combining the WSN and grid computing and shows a sensor grid architecture which is based on an embedded wireless gateway. The software and hardware design of the embedded gateway are described, and the security strategy of this architecture which is based on AES data encryption standard, digital signature and RSA public-key encryption algorithm is proposed. At last, the superiority of this architecture for solving the problems of combining WSN and grid computing are indicated.
