Design of delay tolerant network for remote areas using independent deletion mechanism

Abstract

Delay tolerant network (DTN) provides solution for the implementation of the internet with a new prototype. DTN concept is started from the problems of using TCP/IP on the environmental conditions that are not conducive to end to end connectivity with high delay and disruptions between nodes. The goal of this work is to design the scalability of the DTN based network, by implementing epidemic routing algorithms and independent deletion mechanism in the real environment. The epidemic algorithm commonly has a good delivery rate, merely not well for network resource use. To reduce the excessive use of network resources, this work implements an independent deletion mechanism. This mechanism is divided from the core DTN process. The entire algorithm is implemented in Perl, running in unix system. Applications used for benchmarking this system are using email. From the real world simulation, by implementing independent deletion mechanisms achieved low storage utilization while keeps good delivery rate with the epidemic routing algorithm.
