today, one of the new technologies in the modern era is vehicular ad-hoc network which has takenenormous attention in the recent years. because of rapid topology changing and frequent disconnectionmakes it difficult to design an efficient routing protocol for routing data between vehicles, called v2v orvehicle to vehicle communication and vehicle to roadside infrastructure, called v2i. designin...

INTRODUCTION OPTICAL BURST SWITCHING ALTERNATIVE ROUTING IN OBS NETWORKS SIMULATION AND RESULTS CONCLUSION

This paper introduces efficient routing discovery process based on 6LoWPAN for wireless sensor networks. This approach is performed in the link layer in order to route the data frame through intermediate sensor nodes without processing the headers in the upper layers. As a result, the routing cost is reduced and the routing efficiency is improved. Further, in the approach, a source node creates...

Abstarct: An adaptive management for heterogeneous wireless network is proposed to deal the handoff process and route selection. It consists of a type selection process, a routing discovery process, and a handoff and maintenance process. Furthermore, the routing discovery process includes route discovery phase and route selection phase. Via hybrid wireless networks, one can serve 50% more users...

Cellular manufacturing (CM) is one of the most important subfields in the design of manufacturing systems and as a recently emerged field of study and practice, virtual cellular manufacturing (VCM) inherits the importance from CM. One type of VCM problems is VCM with alternative processing routes from which the route for processing each part should be selected. In this research, a bi-objective ...

This paper proposes a variable neighborhood descent for solving a capacitated arc routing problem with time-dependent service costs. The problem is motivated by winter gritting applications where the timing of each intervention is crucial. The variable neighborhood descent is based on neighborhood structures that manipulate arcs or sequences of arcs. Computational results are reported on proble...

In this paper, we present the results of a study of routing algorithms for traac restoration after a failure in a virtual circuit packet switched wide area network. Standard routing algorithms based on minimizing the steady state network delay may not be appropriate for rerouting the calls after a failure, in view of the transient congestion. Here we propose alternative routing schemes to reduc...

Recent work has focused on increasing availability in the face of Internet path failures. To date, proposed solutions have relied on complex routing and pathmonitoring schemes, trading scalability for availability among a relatively small set of hosts. This paper proposes a simple, scalable approach to recover from Internet path failures. Our contributions are threefold. First, we conduct a bro...

Communication is crucial to the coordination and efficient operation of public transport systems. However, deployment of infrastructure based communication systems is expensive, esp. due to long-term operational costs. Delay tolerant vehicular networks are a promising alternative since only very few infrastructure elements are required. This paper presents a DTN routing algorithm for urban publ...
