E DROP An Effective Drop Buffer Management Policy for DTN Routing Protocols

Abstract

In this paper, we propose effective buffer management drop policy E-DROP for delay tolerant networks. We illustrate that conventional buffer management policy like MOFO be unsuccessful to consider all relevant information in this framework. E-DROP policy can be adjust to minimize the metrics of relayed, dropped , average latency ,overhead ratio ,hop count and to maximize the average delivery probability and buffer time. Using simulations support on an imitation mobility models shortest path map based and Map route movements, we show that our buffer management E-DROP with random message sizes drop policy performs better as the existing MOFO.
