Abstract

Problem 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 problem has been mathematically formulated to a constrained optimization problem using hybrid PSO. Results: In results, we considered that the centralized algorithm requiring a global knowledge of the networks is impractical in large wireless networks, the distributed version of the centralized algorithm requiring multihop neighborhood information under the assumption that limited frequency band is available. Conclusion: A variety of simulations were conducted to examine the performance of the proposed approach and the results show that our algorithm consistently outperforms existing techniques.
