摘要：Secure routing issues, as a crucial research direction of security is emergent and significant in WSN. The existing QoS routing protocol ignores the security design. A secure QoS routing algorithm based on ACO is designed in this paper. This algorithm combines ant colony optimization algorithm with credit evaluation mechanism effectively. In order to achieve good security performance, the creditworthiness of nodes is introduced as the control factor in ant colony algorithm. Firstly the algorithm will kick off the nodes which are not meet QoS needs. The set of candidate nodes will be optimized. Then an optimal route will be got by the improved ACO algorithm. The algorithm prefers the node with high creditworthiness as the next hop, thus this algorithm can avoid some attack and the optimal route has higher reliability. Finally, the security of the algorithm is analyzed from a variety of network attack. © 2013 IEEE.
