The ACO (Ant Colony Optimization) isnovel concept to improves the routing performance of network because multiple choices of path available to deliver data to destination. The link capacity in network is limited and it is also not possible extend easily as wired network. The multipath protocol like AOMDV is balance the load by providing alternative path but not proficient at every condition. The problem of congestion in MANET is not possible to removes completely because of limited bandwidth capacity of link between the two nodes. The transport layer protocol like TCP and UDP is control the communication end to end in dynamic network. In Network both protocols are used for communication. In this paper we measure the performance of TCP and UDP protocol, in dynamic network in presence of DDoS attack and normal ACO routing and proposed secure communication. The attacker behaviour is identified by security mechanism to detect and prevent network from attacker. The packet loss in presence of attacker is more in network but after applying prevention scheme the packet loss is minimized.
