Abstract: Delay Tolerant Networks (DTNs) take high end-to-end latency, which is frequently appearances interruption, and unpredictable wireless connections. DTNs provides a service where network executes commotion or delay. It operates in challenged networks with particularly partial resources such as memory size, CPU processing power etc. This paper presents an effective trust managing mechanism for providing protected environment. The proposed dynamic trust management protocol uses an active threshold apprising which disables the problems with time changing active appearances by dynamically updating the principles in response to changing network conditions. This reduces overheads and increases the efficient use of routing network even in conditions change. Also the dynamic threshold update reduces the false detection probability of the malicious nodes. To show the effectiveness of the proposed system, a detailed simulation in the presence of selfish and malicious nodes is performed with ONE simulator. Finally a comparative analysis of our proposed routing with previous routing protocols is also performed. The consequences demonstrate that presented algorithm deals effectively with selfish behavior with providing significant gain on effective delivery ratio in trade off with message overhead and delay.
