In this paper, we purpose a new routing protocol based on applications of hierarchical routing protocols, named as ldquoMulti-Level Cluster-based Hierarchical Protocolrdquo (MLCP) for large-scale mobile ad hoc networks. Our approach organizes nodes into different levels of clusters. MLCP maintains a hierarchical topology, where elected cluster-heads at(More)
Optimal Communication Spanning Tree (OCST) is a well-known NP-hard problem on the graph that seeks for the spanning tree with the lowest cost. The tree cost depends on the demand and distance between each pair of nodes. This paper presents a Hybrid Genetic Algorithm (HGA) combining the basic GA with the ideas of the Particle Swarm Optimization (PSO)(More)
