Energy Optimized Node Level Trust Based Data Transaction in Wireless Sensor Network

Wireless Sensor Networks (WSN), is widespread used by various fields due to its advantages and application. The major issue focused in a network to increase its performance is energy consumption and secure data transaction without any loss. In our proposed work, secure data transaction is focused through analyzing node trust. The challenge-response model promotes a focus on assessing trust for oneself; And linking it to its sub-center using the proposed self-survey and self-affirmation calculations, respectively. Hence node level trust is evaluated through self scrutiny and self attestation. Self scrutiny is analyzing every nodes self integrity level and self attestation evaluates the trust level of nodes that are included in transaction. In addition to this energy optimization has been implemented, to obtain this Energy Efficient Sensor Routing (EESR) protocol is implemented. This algorithm considers minimum path selection, energy utilization and node trust. To increase the performance based on energy factor, sleep and a wake approach has been used. Compared to existing method our proposed work attains maximum performance in both data delivery and network lifetime parameters.
