Square Code in WSNs (Wireless Sensor Networks)
The proposed Square code has improved area-overhead more than 50% compared with SEC-DED(Single Error Correcting – Double Error Detecting) conventional codes and has a small size packet.
Abstract
This paper proposed the Square code which is appropriate to the WSNs. The Square code can detect failures that are larger than double bits error and can correct failures that are larger than single bit error, and the implementing method is presented in the paper. For an information that are 16 bits long, all kinds of single bit and double bits error can be detected and corrected. For the triple bit errors, all of the errors can be detected and 93.6% can be corrected where the triple bit error combination has 560ea(C(16,3)). Proposed code scheme is suitable in the WSNs because it has a small size packet. Also, this paper classifies a fault model in the sensor node. Proposed Square code has improved area-overhead more than 50% compared with SEC-DED(Single Error Correcting – Double Error Detecting) conventional codes.
