TLDR
The route change latency (RCL) after link failures, a critical performance metric in a non-static ad-hoc scenario, and its dependence on routing protocol parameter settings and implementation issues using OLSR are studied.Abstract:
A key element for MANET performance is the routing protocol. Surprisingly, little effort has been devoted up to now to analyzing the impact of routing protocol parameter settings on MANET performance. We define and study in detail the route change latency (RCL) after link failures, a critical performance metric in a non-static ad-hoc scenario, and its dependence on routing protocol parameter settings and implementation issues using OLSR. We experiment with a set of OLSR settings in a real network environment and derive its potential effect in a generic situation, showing that end-to-end connectivity can be enhanced using different parameter settings from the default ones.read more

Intelligent OLSR Routing Protocol Optimization for VANETs
TL;DR: This paper deals with the optimal parameter setting of the optimized link state routing (OLSR), which is a well-known mobile ad hoc network routing protocol, by defining an optimization problem and finding automatically optimal configurations of this routing protocol.

Tuning OLSR
TL;DR: It is found that the impact of the interval timer grows with increased network mobility and node density, and the intervals for some message types (HELLO messages) have a bigger impact on OLSR performance than for other message types.

TL;DR: A novel design is designed and simulated for a mobile ad hoc network with a low offered load that uses dramatically less power than industry standard protocols and yet achieves higher delivery reliability, handles substantially greater node densities, supports mobility, and has the ability to perform well even under high offered loads.

An Efficient Framework Model for Optimizing Routing Performance in VANETs.
TL;DR: This paper introduces a statistical framework model to address the problem of optimizing routing configuration parameters in Vehicle-to-Vehicle (V2V) communication and shows significant performance improvement in terms of the Packet Delivery Ratio (PDR), Normalized Routing Load (NRL), Packet loss (PL), and End- to-End Delay (E2ED).

Multihop Wireless Networks
TL;DR: In cellular and wireless local area networks, wireless communication only occurs on the last link between a base station and the wireless end system, but in multihop wireless networks, there are one or more intermediate nodes along the path that receive and forward packets via wireless links.

Integrating fast mobility in the OLSR routing protocol
TL;DR: This paper presents an extension of the optimized link state routing protocol (OLSR), denoted Fast-OLSR, which is designed to meet the need for fast mobility in mobile ad-hoc networks (MANETs), and shows that the loss rate can be minimized while maintaining a reasonable overhead traffic.
