Minimizing Delivery Delay Using Novel Estimation Approach

Abstract: Developing a new utility-based message scheduling mechanism that incorporates with DTN message forwarding, where per-message utility is determined to optimize either message delivery ratio or delivery delay. Developing a novel estimation approach for network global knowledge to facilitate decisions on which message should be forwarded/dropped when the buffer of the encountered node is full. Evaluating and comparing the existing scheme with counterparts, and gaining understanding on its trade off between computation complexity and performance improvement. Each node maintaining limited buffer space is full in DTNs. So nodes are dropped the messages at processing unit. In this paper we proposed the network message delivered based automatic removal of unnecessary messages from buffer overflow in DTNs. So buffer space is only maintained for current transaction process in each node. Finally, the DTN node transaction is not delay approach and every time buffer space is free.
