|摘要:||行動特殊網路(Mobile Ad-Hoc Networks, MANETs)的路由演算法，使的無線隨意網路(Ad-Hoc Networks)的傳輸可以藉由鄰近的節點跳躍式的傳輸，這種傳輸的方式依賴的是節點之間的互相信任，當有惡意的節點想使你的路由失敗時，往往就對行動特殊網路造成很大的傷害。
The routing algorithm for the mobile ad-hoc networks enables the ad-hoc networks to use hop-by-hop transmission. This type of the transmission depends on the trust between nodes. If attackers inside the network attempt to fail the routing, it always leads to a lot of damage in the mobile ad-hoc networks routing. Therefore, a mechanism, called “Trust Evaluation Based Security Solution in Ad Hoc Networks ”, is proposed. Its idea is that nodes in the network can turn down the transmission request for untrustworthy nodes. This method cooperates with the source routing for implementing the secure routing. In this way, the trusty path is decided by means of “Trust Evaluation Based Security Solution in Ad Hoc Networks” and then the source chooses the transmission path. If the node which is responsible for transmission can be ensured to be trusty in this method, the secure routing can be completed. However, it is not objective for the source to decide the transmission path. Thus, we propose a distributed mechanism for the secure routing. This mechanism divides a long path into many short paths and in each short path there is a node responsible for choosing the path. By this way, each node only needs to monitor nodes in the region and then the accuracy for trust evaluation can be raised. Besides, the security among the wireless network has to rely on several secure mechanisms and our mechanism proposed in this paper can easily cooperate with other protocols.
