Abstract

This paper introduces a delay-centric link quality aware routing protocol, LQOLSR (Link Quality aware Optimized Link State Routing). The LQOLSR chooses find fast and high quality routes in mobile ad hoc networks (MANET). LQOLSR predicts a packet transmission delay according to multiple transmission rates in IEEE 802.11 and selects the fastest route from source to destination by estimating relative transmission delay between nodes. We implement a LQOLSR protocol by modifying the basic OLSR (Optimized Link State Routing) protocol. We evaluate and analyze the performance in a real testbed established in an office building.
