Today, providing a good quality of service (QoS) in irregular traffic networks is an important challenge. Besides, the impressive emergence and the important demand of the rising generation of real-time Multi-service (such as Data, Voice VoD, Video-Conference, etc.) over communication heterogeneous networks, require scalability while considering a continuous QoS. This emergence of rising genera...

In this paper, we present the simulation results of the comparative investigation of the performance of the wireless sensor network routing protocols based on different routing objective: energy-aware routing using PROWLER and RMASE. Our simulation results indicate that the energy-aware routing objective increases the network lifetime for the Adaptive Tree, Constrained Flooding and Real-Time ro...

The bandwidth-delay-constrained least-cost multicast routing is a challenging problem in high-speed multimedia networks. Computing such a constrained Steiner tree is an NP-complete problem. In this paper, we propose a novel QoS-based multicast routing algorithm based on the genetic algorithms (GA). In the proposed method, the predecessors encoding is used for genotype representation. Some novel...

This paper presents an artificial bee colony (ABC) algorithm adjusted for the capacitated vehicle routing problem. The vehicle routing problem is an NP-hard problem and capacitated vehicle routing problem variant (CVRP) is considered here. The artificial bee metaheuristic was successfully used mostly on continuous unconstrained and constrained problems. Here this algorithm has been implemented ...
