Opportunistic networks (Oppnets) use the Store, Carry, and Forward technique for routing of messages. This technique can increase the prospects of message delivery but it is resource intensive as messages are kept in node's buffer until an appropriate next hop node is find out. This may lead to increased overhead and buffer overflow that causes congestion. In view of this, a scheme based on centrality...
In this paper, we propose an efficient deflection routing method to improve the burst loss performance in Optical Burst Switching (OBS) networks. We show that the proposed scheme gives significant reduction in burst loss rate as compared to conventional technique for optical networks. To improve the burst loss performance, the proposed variable size burst routing algorithm (VSBR), dynamically determines...
