Paper: Optimizing Route Length in Reactive Protocols for Ad Hoc Networks

Many protocols for Mobile Ad-hoc Networks propose construction of routes reactively using flooding. The advantage hereof is that no prior assumption of the network topology is required in order to provide routing between any pair of nodes in the network....

Paper: Performance analysis of Trickle as a flooding mechanism

“The Trickle Algorithm” is conceived as an adaptive mechanism for allowing efficient and reliable information sharing among nodes, communicating across a lossy and shared medium. Its basic principle is, for each node, to monitor transmissions from its neighbours, compare what...

Paper: A Study of Link Buffering for OLSR

In this paper, we propose an extension of the Optimized Link State Routing (OLSR) protocol based on link layer notification, “link buffering” and “packet restoration”. When link disconnection is detected by link layer notification, the route entries having the disconnected...

Paper: Analyzing control traffic overhead in mobile ad-hoc network protocols versus mobility and data traffic activity

This paper proposes a general, parameterized model for analyzing protocol control overheads in mobile ad-hoc networks. A probabilistic model for the network topology and the data traffic is proposed in order to estimate overhead due to control packets of routing...

Bad Science: Euh…*Optimistic* Link State Routing Protocol for Adhoc Networks????

Paper: Vulnerability Analysis of the Optimized Link State Routing Protocol version 2 (OLSRv2)

Mobile Ad hoc NETworks (MANETs) are leaving the confines of research laboratories, to find place in real-world deploy-ments. Outside specialized domains (military, vehicular, etc.), city-wide community-networks are emerging, connecting regular Internet users with each other, and with the Internet, via...
