The natural or man-made disaster demands an efficient communication and coordination among first responders for successful emergency management operations. During emergency situations such as an earthquake or a flood, the traditional telecommunication infrastructure may be damaged and may not provide adequate communication services to emergency management teams. Mobile ad hoc networks are used ...

in the recent decade, special attention is paid to reverse logistic due to economic benefits of recovery and recycling of used products as well as environmental legislation and social concerns. on the other hand، many researches claim that separately and sequential planning of forward and reverse logistic causes sub-optimality. effective transport activities are also one of the most important c...

Nowadays Network-on-Chips is used instead of System-on-Chips for better performance. This paper presents a new algorithm to find a shorter path, and shows that genetic algorithm is a potential technique for solving routing problem for mesh topology in on-chip-network.

the hierarchical hub location problem is encountered three-level network that is applied in production-distribution system, education system, emergency medical services, telecommunication network, etc. this paper addresses the hierarchical hub covering problem with single assignment accounting for mandatory dispersion of central hubs restriction as a special case. this formulation with incorpor...

in this paper, we present a novel algorithm for vanet using cloud computing. we accomplish processing, routing and traffic control in a centralized and parallel way by adding one or more server to the network. each car or node is considered a client, in such a manner that routing, traffic control, getting information from client and data processing and storing are performed by one or more serve...
