today, transportation of hazardous materials (i.e., hazmat) is a very important issue for researchersdue to the risk of this transit, which should be considered for development of industries and transportation.therefore, a model that is useful should consider the risk and damage to humanitarianand environmental issues due to transit of hazmat materials. by considering the related cost, thereali...

In the median cycle problem the aim is to determine a simple cycle through a subset of vertices of a graph involving two types of costs: a routing cost associated with the cycle itself, and the cost of assigning vertices not on the cycle to visited vertices. The objective is to minimize the routing cost, subject to an upper bound on the total assignment cost. This problem arises in the location...

The mobile nodes in MANETs dynamically change their topology and hence require an efficient mechanism to communicate with each other. There are number of routing protocols anticipated for MANET environment categorized as Location based routing protocols and Non-Location based routing protocols. In MANETs, Location based routing protocols are preferred as they are more efficient in routing compa...

Troop movement involves transporting military personnel from one location to another using available means. To minimize damage enemies, the simultaneously uses reconnaissance and transportation units during troop movements. This paper proposes a vehicle routing problem considering (VRPCRT) for wartime The VRPCRT is formulated as mixed-integer programming model minimizing completion time of move...

Vehicular ad hoc networks (VANETs) are the technical basis of an envisioned Intelligent transportation system. They offer a wide range of applications improving road safety and driving comfort. Since VANET applications affect safety-of-life, data security in a vehicular system is mandatory. The unique characteristics of VANETs compared to conventional mobile ad hoc networks and sensor networks ...
