We show how effectively the diffusive capture processes (DCP) on complex networks can be applied to information search in the networks. Numerical simulations show that our method generates only 2% of traffic compared with the most popular flooding-based query-packet-forwarding (FB) algorithm. We find that the average searching time, 〈T 〉, of the our model is more scalable than another well know...

We introduced the use of two-hop forwarding to increase the throughput of an 802.11 network in our earlier work (Narayanan et al., Proceedings of IEEE WCNC’05, March 2005). Other researchers have also considered the benefits of forwarding in the 802.11 infrastructure mode to increase the total network throughput. But the high-data rate node that forwards data for other nodes will have to spend ...

This paper studies the efficient integration of gateway forwarding strategies in wireless ad hoc networks. The problem to solve is the forwarding to one or more gateways in an environment where there is no hierarchical addressing. We provide an overview of the challenges in this area and then compare the properties of two proposed forwarding strategies; traditional default routes and tunnels. W...

Routing packets along a specified curve is a new approach to forwarding packets in large-scale dense sensor networks. Forwarding packets along trajectories can be very effective in implementing many networking functions when standard bootstrapping or configuration services are not available, as will be the case in sensor networks where nodes are thrown or dropped to form a one-time use network....

Word spotting is to make searchable unindexed image documents by locating word/words in a doc-ument image, given a query word. This problem is challenging, mainly due to the large numberof word classes with very small inter-class and substantial intra-class distances. In this paper, asegmentation-based word spotting method is presented for multi-writer Persian handwritten doc-...
