In the context of Delay Tolerant Networks (DTNs), where nodes operate as mobile devices with intermittent and limited connectivity, the energy efficiency of routing protocols is a critical consideration. Unlike traditional Mobile Ad Hoc Networks (MANETs), DTNs lack constant interconnections between network devices, posing challenges for optimal energy utilization. This study investigates various DTN routing protocols, including Epidemic, Spray and Focus, Spray and Wait, MaxProp, and PRoPHET, with a focus on their energy consumption patterns. The evaluation is conducted through a comprehensive performance analysis, considering average hop count, average latency, delivery probability, and transmission cost. Using the ONE simulator, simulations are performed under varying node density and buffer size conditions, while keeping the Time-To-Live (TTL) fixed. Results indicate that Spray and Focus emerges as the top performer in terms of average hop count, average latency, delivery probability among conventional DTN routing protocols. Conversely, Spray and Wait exhibits superior energy efficiency, establishing itself as the most energy efficient DTN routing protocol. This research underscores the importance of selecting routing protocols that not only enhance network performance but also address the crucial factor of energy consumption in DTN scenarios.

摘要

In the context of Delay Tolerant Networks (DTNs), where nodes operate as mobile devices with intermittent and limited connectivity, the energy efficiency of routing protocols is a critical consideration. Unlike traditional Mobile Ad Hoc Networks (MANETs), DTNs lack constant interconnections between network devices, posing challenges for optimal energy utilization. This study investigates various DTN routing protocols, including Epidemic, Spray and Focus, Spray and Wait, MaxProp, and PRoPHET, with a focus on their energy consumption patterns. The evaluation is conducted through a comprehensive performance analysis, considering average hop count, average latency, delivery probability, and transmission cost. Using the ONE simulator, simulations are performed under varying node density and buffer size conditions, while keeping the Time-To-Live (TTL) fixed. Results indicate that Spray and Focus emerges as the top performer in terms of average hop count, average latency, delivery probability among conventional DTN routing protocols. Conversely, Spray and Wait exhibits superior energy efficiency, establishing itself as the most energy efficient DTN routing protocol. This research underscores the importance of selecting routing protocols that not only enhance network performance but also address the crucial factor of energy consumption in DTN scenarios.
