This document discusses performance evaluation of quality of service (QoS) in mobile ad hoc networks (MANETs) using an enhanced ant colony optimization (ACO) approach combined with hybrid routing protocols. It first provides background on MANETs and challenges related to their dynamic topology and limited resources. It then discusses using ACO, which is based on how ants deposit and follow pheromone trails, to continuously update path pheromone values based on parameters like residual signal strength, energy, and hop count to select optimal routes. The objective is to improve QoS satisfaction for tactical communications requiring multimedia data transfer with good quality. The document reviews several existing approaches that aim to improve QoS in MANETs and
