A Multi-objective Differential Evolution for QoS Multicast Routing

This paper presents a new multi-objective differential evolution algorithm (MODEMR) to solve the QoS multicast routing problem, which is a well-known NP-hard problem in mobile Ad Hoc networks. In the MODEMR, the network lifetime, cost, delay, jitter and bandwidth are considered as five objectives. Furthermore, three QoS constraints which are maximum allowed delay, maximum allowed jitter, and minimum requested bandwidth are included. In addition, we modify the crossover and mutation operators to build the shortest-path multicast tree to maximize network lifetime and bandwidth, minimize cost, delay and jitter. In order to evaluate the performance and the effectiveness of MODEMR, the experiments are conducted and compared with other algorithms for these problems. The simulation results show that our proposed method is capable of achieving faster convergence and more preferable for multicast routing in mobile Ad Hoc networks.
