Cooperative node selection scheme based on credibility in wireless sensor network

Selecting a reliable node is a guarantee for cooperative transmission in wireless sensor networks. These nodes assist cluster heads to transmit information to remote data fusion centers. In order to reduce the impact of nodes with low reliability on cooperative transmission in WSN, a cooperative node selection scheme based on credibility is proposed. Simultaneous interpreting the reliability of its cooperative nodes before selecting cooperative nodes, only nodes with high credibility will be selected as cooperative nodes, avoiding simultaneous interpreting of potential malicious nodes.
