摘要：In wireless sensor networks (WSNs), the present bunch based information accumulation procedure
expends more vitality. Additionally the secured information transmissions are essential for upgrading the information
confirmation and secrecy. Keeping in mind the end goal to conquer these issues, in this review, In this paper, we
provide detailed analysis on the relations between clustering and routing, and then propose a Ambient Trust Sensor
Routing (ATSR) protocol for reliable and efficient data collection in large-scale wireless sensor network. ATSR adopts
the back off timer and gradient routing to generate connected and efficient inter-cluster topology with the constraint of
maximum transmission range. The relations between clustering and routing in ATSR are further exploited by
theoretical and numerical analysis. The results show that the multi-hop routing in ATSR may lead to the unbalanced
cluster head selection. Then the solution is provided to optimize the network lifetime by considering the gradient of
one-hop neighbor nodes in the setting of back off timer. Theoretical analysis and simulation results prove the
connectivity and efficiency of the network topology generated by ATSR.
