routing in wireless sensor networks (wsns) is a very challenging task due to the large number of nodes, their mobility and lack of proper infrastructure. since the sensors are battery powered devices, energy efficiency is considered as one of the main factors in designing routing protocols in wsns. most of energy-aware routing protocols are mere energy savers that attempt to decrease the energy...

Network performance is a critical aspect of highperformance computers, and improving its performance is a major goal in the design of future systems; this work proposes to improve network performance through new routing algorithms, leveraging the rich multi-path topologies of multi-dimensional torus networks commonly found in supercomputers built in the past fifteen years. Virtually all torus n...

O objetivo deste estudo é desenvolver uma solução para o problema de distribuição proposto pelos jogos matemáticos 2017-2018, organizado conjuntamente pela Federação Francesa Jogos Matemáticos e Empresa Modelagem Matemática. Conhecido na literatura como um produção-estoque-distribuição-roteamento (PIDRP), este otimização combinatória NP-difícil, ainda pouco explorado literatura. Esta pesquisa b...

in mobile ad hoc networks, the absence ofinfrastructure and the consequent absence of authorizationfacilities impede the usual practice of establishing a practicalcriterion to distinguishing nodes as trusted and distrusted.since all nodes in the manets would be used as router inmulti-hop applications, secure routing protocols have vital rulein the security of the network. so evaluating the perf...

Despite the fact that there is a large body of literature on Production Routing Problem (PRP), we were struck by dearth research outsource planning and lateral transshipment. This paper presents mixed-integer linear programming model for incorporating outsourcing, transshipment, back ordering, lost sales, time windows into production routing problems. Then robust optimization will be introduced...

We consider a single item Production-Inventory-Routing problem with a single producer/supplier and multiple retailers. Inventory management constraints are considered both at the producer and at the retailers, following a vendor managed inventory approach, where the supplier monitors the inventory at retailers and decides on the replenishment policy for each retailer. We assume a constant produ...

in this study the location routing problem with fuzzy parameters is taken into account, this problem involves determining the location of the depots and routing of the vehicles in order to serve the customers. in this study a location routing problem with fuzzy travel times and due dates is considered and two objective models are proposed. the considered objectives are minimizing the total cost...

Abstract- Efficient message delivery in city environment is required to ensure driver’s safety and passenger’s comfortability. In cities of developed nations, routing of data in vehicular Ad hoc Network (VANET) faces many challenges such as radio obstacles, mobility constraints and uneven nodes distribution. These factors primarily makes communication between vehicles complex. To overcome and t...
