Forwarding impact aware routing protocol for Delay Tolerant Network
The Delay Tolerant Network (DTN) multi-copy protocols transmits multiple copies of each message on all or several neighbors. Hence, message can reach to its destination via multiple nodes at higher consumption of buffer space, energy and bandwidth. This paper has proposed a Forwarding Impact Aware P...

| Summary: | The Delay Tolerant Network (DTN) multi-copy protocols transmits multiple copies of each message on all or several neighbors. Hence, message can reach to its destination via multiple nodes at higher consumption of buffer space, energy and bandwidth. This paper has proposed a Forwarding Impact Aware Probabilistic Routing Protocol (FIAR) to control the redundant message transmission. The FIAR has used two metrics called as Forwarding Impact (FI) and Drop Impact. The Forwarding Impact (FI) is used to decide which message to forward when connection opportunity arises while Drop Impact (DI) is used to decide which message to drop when a node receives a message with no buffer space. Simulation results shown that proposed FIAR outperforms existing Epidemic protocol, Prophet protocol and Spray and Wait routing protocol in terms of reducing the number of transmissions, message drop and raising delivery ratio. |
