Cross-Layer Design to Maintain Earthquake Sensor Network Connectivity After Loss of Infrastructure

, 2012
We present the design of a cross-layer protocol to maintain connectivity in an earthquake monitoring and early warning sensor network in the absence of communications infrastructure. Such systems, by design, warn of events that severely damage or destroy

Enhancing Data Security through Hybrid Error Detection: Combining Cyclic Redundancy Check (CRC) and Checksum Techniques

International Journal of Electrical and Electronics Research
Error detection is a critical aspect of ensuring the accuracy of data transmission in communication systems. In this study, the performance of two error detection techniques has been investigated when combined to achieve a Bit Error Rate of 10^(-5)for single and multiple error detection ability.

CRC-Aided Logarithmic Stack Decoding of Polar Codes for Ultra Reliable Low Latency Communication in 3GPP New Radio

IEEE Access, 2019
This paper provides a detailed tutorial on the Cyclic Redundancy Check (CRC)-aided logarithmic successive cancellation stack (Log-SCS) algorithm. We apply these algorithms for the ultrareliable decoding of polar codes, which has relevance for the control
