Multi-Objective Cross-Layer Optimization with Pareto Method for Relay Selection in Multihop Wireless Ad hoc Networks

چکیده
The focus of this paper is cross layer optimization of relay selection on multihop wireless ad hoc networks. Cross-layer metrics that will be optimized are power consumption, throughput, and load balancing in wireless ad hoc networks for the outdoor and indoor configurations. Those three resources (performance indicators) are optimized using the multi objective optimization with Pareto method. The results obtained apply a dynamic ad hoc network model and optimization can be done simultaneously to all three resources which are optimized based on the route or path. Several alternatives in the relay selection are shown in the following simulation. The selection of the optimal relay can be based on one or a combination of the three performance indicators. The performance of the optimal relay selection in the field of POF (Pareto Optimal Front) is shown by the shortest Euclidean distance. The result of optimization for indoor and outdoor multihop ad hoc networks with three performance indicators is shown. Key-Words: Multi Objective Optimization, Cross Layer, Pareto Method, Relay Selection, Euclidean Distance, Multihop Wireless Ad hoc Networks, Performance Indicator, Outdoor and Indoor Configuration

متن کاملDistributed Cross-layer Dynamic Route Selection in Wireless Multiuser Multihop Networks
In wireless ad-hoc networks, forwarding data through intermediate relays extends the coverage area and enhances the network throughput. We consider a general wireless multiuser multihop transmission, where each data flow is subject to a constraint on the end-to-end buffering delay and the associated packet drop rate as a quality of service (QoS) requirement. The objective is to maximize the wei...
