Efficient Erasure Code for Wireless Sensor Networks

Overview Reliable communication in Wireless Sensor Networks is hard to achieve efficiently using methods in conventional systems like Internet. End-to-end retransmission is inefficient, or in some cases impossible. Erasure code is code with which ONE can reconstruct m original messages by receiving any m out of n code words (n > m). Erasure code provides efficient option for achieving reliability. Erasure code based on Reed-Solomon code is implemented. And further modifications were made to optimize for resource-constrained Wireless Sensor Networks mote. Systematic code is used to increase speed of decoding.
