Enhancement of Binary Spray and Wait Routing Protocol for Improving Delivery Probability and Latency in a Delay Tolerant Network

Abstract

In this paper, we enhanced the Binary Spray and Wait (B-S&W) routing protocol and create two versions of Spray and Wait (S&W-V1 and S&W-V2) and evaluate and compare their performance in a Delay Tolerant Network (DTN). The network is created from pedestrians, cars and buses of public transport, equipped with smart devices that move and exchange information in an urban area in Tirana city, Albania. Different simulations are conducted to evaluate the performance of the enhanced protocols. Simulations are done using the Opportunistic Network Environment (ONE) simulator. We use the delivery probability and average latency as evaluation metrics. Based on simulation results, we found that our proposed versions S&W-V1 and S&W-V2 improve the delivery probability and average latency.
