Title: Device to Device Communication in Mobile Delay Tolerant Networks
Published: Proceedings of the International Symposium on Distributed Simulation and Real-Time Applications, , pp. 1-8, Rome, Italy, October 2017
Abstract: Available smartphones and smart objects can use short range connections like Wi-Fi and Bluetooth as a communication technique to exchange information with nearby devices.Those techniques are used in cases of absent end-to-end connection such as in Delay Tolerant or Opportunistic Networks.The study of message transmission processes and contact information in such networks has gained more attention nowadays, where contact information and message transfer have a great impact on Store-Carry-Forward routing decisions.The performance of routing mechanisms is measured based on bandwidth utilization and energy consumption regarding the delivery ratio.Therefore, in this paper we present a study framework to formulate the message propagation process in addition to contact information with a view on energy consumption.The study gives a detailed expression of contact information such as contact probability based on node density and transmission range in a bounded area.Furthermore, the message exchange process as element of channel utilization and energy consumption will be studied.Based on our simulation experiment results we evaluate the influence of various parameters on each other and finally on the system performance.
