Providing safe transportation for Hazardous Materials (Hazmat) is a concern that attracts a wide range of resaerchers. Different types of problems have been defined in the literature in order to cope as much as possible with real situations. Most of existing studies consider the transportation between two points, while few of them considered resolving the Vehicle Routing Problem (VRP) in the co...

This paper presents a routing optimization model for wide range of waste collection problems which allows multiple depots with homogeneous, capacitated vehicles, intermediate stops at processing facilities, and pick-ups per location. By minimizing vehicle investment costs, the estimates total transportation costs given network design volumes to be collected different demand points. The number f...

We propose probabilistic location to enhance the performance of existing peer-to-peer location mechanisms in the case where a replica for the queried data item exists close to the query source. We introduce the attenuated Bloom filter, a lossy distributed index. We describe how to use these data structures for document location and how to maintain them despite document motion. We include a deta...

Sensor networks are wireless adhoc networks where all the nodes cooperate for routing messages in the absence of a fixed infrastructure. Non-flooding, guaranteed delivery routing protocols are preferred because sensor networks have limited battery life. Location aware routing protocols are good candidates for sensor network applications, nevertheless they need either an external location servic...

a significant portion of gross domestic production (gdp) in any country belongs to the transportation system. transportation equipment, in the other hand, is supposed to be great consumer of oil products. many attempts have been assigned to the vehicles to cut down greenhouse gas (ghg). in this paper a novel heuristic algorithm based on clark and wright algorithm called green clark and wright (...

for last years, the evolution of new issues has incited a great development of the transportation system. in this paper, we discuss ingredients of its (intelligent transportation system) that are inter-vehicle communication (ivc) or what can call vehicular ad hoc networks (vanet), which are special type of manet. we will survey the main issues relevant to vanet in detail with providing a concep...

A mobile ad hoc network (MANET) is a characterized by multi-hop wireless links, absence of any cellular infrastructure, and frequent host mobility. Existing MANET routing protocols are divided into location-aware and non-locationaware routing protocols. In a location-aware routing protocol, location information can be exploited to facilitate routing. Our protocol, namely multi-eye spiral-hoppin...

Excessive greenhouse gas emissions from the transportation sector have led companies to move towards a sustainable supply chain network design. In this study we present new bi-objective non-linear formulation where multiple inventory components are integrated into location and routing decisions throughout network. To efficiently solve proposed model, implement an exact method four evolutionary ...

Several applications of mobile ad hoc networks select geographical routing especially the Greedy Perimeter Stateless Routing (GPSR) protocol due to its scalability, efficiency, and ability to support location based applications. However, there are many security issues in protecting location information, which can easily be abused by attackers. Location based adversarial activities affect the op...

    Hub covering location problem, Network design,   Single machine scheduling, Genetic algorithm,   Shuffled frog leaping algorithm   Hub location problems (HLP) are synthetic optimization problems that appears in telecommunication and transportation networks where nodes send and receive commodities (i.e., data transmissions, passengers transportation, express packages, postal deliveries, etc....
