Safety relay selection algorithms based on fuzzy relationship for wireless sensor networks

摘要

The remote nodes using a selecting relay algorithm (SRA) transmit its dates on wireless sensor networks (WSNs). The algorithm can enhance the network life cycle. It selects an appropriate cooperation node as a relay node by balancing between power consumption and communication. More recently, scholars have applied a fuzzy theory to SRA and achieved better tradeoffs. This study further simulates the application of four set types of attacks each layer on WSNS. Then, comparing with different fuzzification and defuzzification methods, a fuzzy inference system was built for the security performance. The results show that there are two methods which can improve the algorithm's safety: one is fuzzification Or-Max connection Method, and the other is defuzzification of Lom and Som methods.
