Adaptive Forwarding to Match Mobility Characteristics in Delay Tolerant Networks

In this paper, we propose an adaptive and opportunistic forwarding mechanism that is able to match mobility characteristics in Delay Tolerant Networks (DTNs). Our protocol, Seeker, empowers nodes with the ability to estimate future contact opportunities based on a history of pair-wise contacts. Furthermore, Seeker is able to adjust and rewind forwarding and buffering decisions on the fly. This ...

- 1 - The Main Questions to be Asked in order to Characterize an ATM Switch Performance Model

Performance of ATM networks will depend on switch performance and architecture. In this paper a set of eleven questions is presented in order to be able to study the performance. It is necessary to clearly identify the main characteristics of the switch architecture and the traffic that are considered. They concern the level of study, the placement of the memory, the monopath or multipath archi...

An analysis of the Multi-Point Relays selection in OLSR

OLSR is a recent routing protocol for multi-hop wireless ad-hoc networks standardized by the IETF. It uses the concept of Multi-Point Relays (MPR) to minimize the overhead of routing messages and limit the harmful effects of broadcast in such networks. In this report, we are interested in the performance evaluation of Multi-Point Relays selection. We analyze the mean number of selected MPR in t...
