Research ArticleOpen accessIn the author namesOptimal Power Multicast Problem in Wireless Mesh Networks by Using a Hybrid Particle Swarm OptimizationAllam Maalla, Chen Wei, Haitham J. TahaProblem statement: Most mobile nodes in a wireless ad hoc network are powered by energy limited batteries; the limited battery lifetime imposes a constraint on the network performance. Therefore, power consumption of network operations is critical and subject to optimization. Approach: A novel hybrid PSO was proposed for solving the minimum power multicast problem in wireless ad-hoc networks. The MPM … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 6,809 accessesView PDF Cite
