An Empirical Evaluation of the Student-Net Delay Tolerant Network

Jing Su, Ashvin Goel, Eyal de Lara
2006 2006 3rd Annual International Conference on Mobile and Ubiquitous Systems - Workshops  
The network has good connectivity, so that routes exist between almost all study participants via some multi-hop path. Moreover, it is possible to effectively route packets with modest replication.  ...  Since mobile devices in a delay-tolerant network forward packets to nearby users, the devices can use short-range radio, which potentially reduces device power consumption and radio contention.  ...  Their generous contribution, under grant number 69470, has helped make this research possible.  ...

E DROP An Effective Drop Buffer Management Policy for DTN Routing Protocols

Sulma Rashid, Qaisar Ayub, M. Soperi Mohd Zahid, A.Hanan Abdullah
2011 International Journal of Computer Applications  
In Delay Tolerant Networks (DTN) disruptions may happen frequently as end to end path is not available all the time.  ...  In this paper, we propose effective buffer management drop policy E-DROP for delay tolerant networks.  ...  In first contact [1], [2] routing, the router transmits the message randomly as other nodes come under its communication range. Under congested networks the messages can not route.  ...

Offloading Multiple Mobile Data Contents Through Opportunistic Device-to-Device Communications

Ray-Guang Cheng, Nien-Sheng Chen, Yu-Feng Chou, Zdenek Becvar
2015 Wireless personal communications  
In opportunistic D2D communication, the network has to appoint relaying users to distribute content(s) to normal subscribers under a given delay-tolerance threshold.  ...  An analytical model is then presented to estimate the amount of reduced mobile data traffic under singlehop and multi-hop opportunistic forwarding scenarios.  ...  It is found that the proposed algorithm is preferable for short delay-tolerance threshold and few relaying users in both single as well as multi-hop forwarding schemes.  ...
