A multicast QoS routing algorithm based on immune genetic algorithm to balance the load in the network was proposed. This paper proposes the network model which supports QoS multicast. With the optimization of existing QoS multicast routing algorithms, this paper proposes an improved multi-constrained for load balancing QoS multicast routing algorithm based on immune genetic algorithm. The simulation...
For the multi-constrained routing problem, there are several constrained parameters such as the bandwidth, delay, packet loss rate, delay jitter, the QoS parameters influence each other. It has been proved as a NP-Complete problem, traditional linear method often have some difficulties in solving this problem. The application of ant colony algorithm or genetic algorithm often has a slow convergence...
This paper proposes the network model which supports QoS multicast. With the optimization of existing QoS multicast routing algorithms, this paper proposes the QoS multicast routing algorithm based on immune genetic method in NGN. The simulation results indicate that the algorithm has high convergence speed and reliability, and can meets the demand of QoS multicast in NGN well.
Wireless multimedia sensor networks are often used to transfer large amount of data such as audio, video and image, and to process complicated tasks. In recent years, the interest in WMSNs are growing dramatically. An algorithm of multicast routing based on genetic algorithm(GA) is presented in this paper. This algorithm provides multiple QoS guarantee, such as bandwidth, delay and delay jitter. The...
QoS multicast routing problem is a nonlinear combination optimization problem, which has been proved to be a NP complete problem. a hybrid algorithm with ant colony optimization algorithm(ACO) and particle a warm optimization algorithm(PSO) is presented. The ACO-GA algorithm absorbs the merits of ACO and GA respectively. In hybrid algorithm, the position update of PSO is used to regulate the solution...
The increasing demand of real-time multimedia applications in wireless environment requires stringent quality of service (QoS) provisioning to the mobile hosts (MH). The scenario becomes more complex during group communication from single source to multiple destinations. Fulfilling users demand with respect to delay, jitter, available bandwidth, packet loss rate and cost associated with the communication...
The problem of multicast routing with multiple QoS constraints is NP complete problem. Most of the multimedia applications require strict QoS guarantee during the communication between a single source and multiple destinations. This gives rise to the need for an efficient QoS multicast routing strategy. Determination of such QoS-based optimal multicast routes basically leads to a multi-objective optimization...
Based on QoS constraints such as delay, delay jitter, bandwidth and packet loss metrics this paper describes a network model suitable for investigating the routing problem and presents a multicast routing algorithm with multiple QoS constraints based on GA and TS hybrid strategy. This algorithm takes advantage of GA and TS and overcomes the shortcomings of GA used in solving the multicast routing...
In this paper, a QoS multicast routing algorithm in IP/DWDM optical Internet is proposed. Given a user request, a bandwidth, delay jitter and error rate bounded and cost optimized QoS multicast routing tree is constructed based on the evolutionary-simplex-algorithm, taking network load balancing into account. Simulation results have shown that it is not only feasible and effective but also advantageous...
