Mobile Agents are softwares migrating from one node to another to fulfill the task of its owner. The introduction of mobile agents has reduced network latency, network traffic a lot but at the same time it has increased the vulnerability for attacks by malicious hosts. One such attack is 'Denial of Service', once the agent is launched it is free to roam without any control of its owner, this on one hand decreases the cost of agent—owner interaction and on the other hand increases the chances of 'Denial Of Service'. In Denial Of Service attack the malicious host may deny resources required by the agent and kill the agent, thus the result computed so far is lost and this may happen every time the agent visits any malicious host. In this paper we continued the work done in [10] in which the authors proposed techniques by which owner can detect the malicious host for 'Denial Of Service' but they did not covered technique for dynamic routes i.e. where the host or agent initiate migrations to hosts which were not contained in the route composed by the owner. We introduced an algorithm and a model which can be useful for the above purpose.
