Factor effects for routing in a delay-tolerant wireless sensor network for lake environment monitoring

Abstract

Delay-tolerant wireless sensor networks (DTWSN) is a promising tool to facilitate communication in disruptive and challenged sensor network environments not usually catered by traditional systems. In this paper, DTWSN application to a real-life lake scenario is considered with the description of the routing problem and proposed solution. Opportunistic Network Environment (ONE) simulator was utilized to determine the performance of First Contact, Epidemic and Spray and Wait routing protocols on the map-based mobility model of the lake. Factors considered are the number of nodes, bit rate and ferry speed. Analyses of delivery probability, latency and overhead ratio as well as buffer time and hop count as metrics of performance evaluation against the protocols are done using JMP software. Results revealed that Spray and wait outperforms the other protocols for the given scenario.
