Minimum Energy Channel Codes For Nanoscale Wireless Communication With Node Density Limits

It is essential to develop energy-efficient communication techniques for nanoscale wireless communications. In this paper, the maximum node density is also considered for minimum energy coding scheme (MEC) for wireless nanosensor networks (WNSNs). The node density of MEC is compared with the node densities of other coding schemes. Discovering the maximum nanonode density is important, since it indicates the communication and computation capability of a nanonetwork within a given amount of area. MEC maintains the desired code distance to provide reliability, while minimizing energy. Performance evaluations show that MEC outperforms popular codes such as Hamming, Reed- Solomon and Golay in the average codeword energy sense.
