Delay Tolerant Networks for Intermittently Connected Mobile Networks

Self Adaptive Utility based Routing protocol SAURP is characterized by the ability of identifying probable opportunities of forwarding messages to their destination through a novel utility task based mechanism in which a suite of environment parameters, such as wireless channel situation, nodal buffer possession, and encounter information, are jointly considered. SAURP can resend messages among nodes on condition that high buffer occupancy, wireless interference and congestion by providing small number of transmissions. The developed utility function in SAURP is proved to be able to achieve finest performance, which is further analyzed via a stochastic approach. Extensive simulation are conducted to verify the developed logical model and compare the proposed SAURP with a number of recently reported stumble upon-base routing approaches in terms of delivery proportion deliverance disruption, and the number of transmissions required for each message delivery. The simulation results show that SAURP Performance all the counterpart multi-copy stumble upon-based routing protocols considered in the study. In this we introduce a novel multi-copy routing protocol, called Self Adaptive Utility-based Routing Protocol (SAURP), for Delay Tolerant Networks (DTNs) that are possibly composed of a huge number of devices in miniature such as smart phones of various capacities in terms of energy resources and buffer spaces.
