Simulation Research of the QoS Multicast Routing in WSN Based on QPSO Algorithm

The energy constraint bottleneck in the wireless sensor networks (WSN) exist objectively. To reduce energy consumption and ensure the Quality of Service (QoS) in data transmission, a method of solving the QoS multicast routing in WSN by quantum particle swarm optimization algorithm (QPSO). The algorithm is based on PSO, quantum-bit, principle of superposition and quantum gates. By the premise of avoiding local convergence and reducing the energy consumption, it can solving the QoS multicast routing rapidly, which help to prolong the network lifetime efficiently. The simulation results indicate that its feasibility and effectiveness.
