Moreover due to the QoS requirements, the RWA is not only required to utilize network resources efficiently during the setup of lightpaths for newly arriving demands, but it is also required not to interrupt lightpaths that are in progress. These constraints dictate the optimization of the RWA for each individual connection request separately as it arrives with the objective of allocating minimum bandwidth based on the network status at the time of the arrival. This paper proposes a new algorithm for shared protection RWA under dynamic traffic for wavelength-routed mesh network with no wavelength conversion. The algorithm is based on the iterative two step approach proposed for networks, with full wavelength conversion. Two wavelength assignment schemes were evaluated and the results are presented.","PeriodicalId":255955,"journal":{"name":"2005 Systems Communications (ICW'05, ICHSN'05, ICMCS'05, SENET'05)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125191721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although, the presented approach can be implemented in any large backbone network that employs multicast communication mode, we concentrate our discussion on MPLS networks. In the proposed approach, a multicast tree is divided into several domains where each domain represents a sub-tree of the original one. Backup paths are built between the root of the domain and each leaf router which is called a border router. Simulation results conducted on two network topologies show the performance of the proposed approach in terms of the total capacity required for reserving the backup paths and in terms of the maximum delay needed to notify about link/node failure. The results have shown that tree division approach compared with global recovery approach reduces the time needed to notify the router that is responsible for switching the traffic to the backup path.","PeriodicalId":255955,"journal":{"name":"2005 Systems Communications (ICW'05, ICHSN'05, ICMCS'05, SENET'05)","volume":"43 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120922977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It allows to edit spatial environments with polygonal obstacles to he used within simulations. It also allows to visualize an animation of the generated mobility traces.

Contrary to MANET in VANET nodes which are vehicles can move with high speed and generally must communicate quickly and reliably. When an accident occurs in a road or highway, alarm messages must be disseminated, instead of ad-hoc routed, to inform all other vehicles. To position a broken vehicle (or vehicle in danger) and locate the vehicles in its vicinity is very important for the safety of the road users. However, vehicles are not necessarily equipped with GPS and even they cannot obtain availability of line of sight access to satellites, particularly when they enter tunnels. In this paper, we propose an improvement to ODAM (optimized dissemination of alarm messages) protocol in order to support localization of GPS-unequipped vehicles. So, the number of vehicles discovering their localisation will be increased. This prevents pile-up of cars when fog, accidents or any other obstacle contributes to the driver safety. Analyses show that the optimal performances of ODAM can be reached even when the rate of GPS-unequipped vehicles is 40%","PeriodicalId":255955,"journal":{"name":"2005 Systems Communications (ICW'05, ICHSN'05, ICMCS'05, SENET'05)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117009844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, in this paper, we present FATOMAS, a java based fault-tolerant mobile agent system based on an algorithm presented in an earlier paper. In contrary to the standard \"place-dependent\" architectural approach, FATOMAS uses the novel agent-dependent approach introduced in the paper. In this approach, the protocol that provides fault tolerance travels with the agent. This has the important advantage to allow fault-tolerant mobile agent execution with out the need to modify the underlying mobile agent platform. We derive the FATOMAS (Fault-Tolerant Mobile Agent System) design which offers a user transparent fault tolerance that can be activated on request, according to the needs of the task, also discuss how transactional agent with types of commitment constraints can commit. Furthermore this paper proposes a solution for effective agent deployment using dynamic agent domains.","PeriodicalId":255955,"journal":{"name":"2005 Systems Communications (ICW'05, ICHSN'05, ICMCS'05, SENET'05)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128666082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The service was designed taking advantage of features provided by the MPLS technology and also using the DiffServ architecture. So, it uses L2 MPLS VPNs to provide point to point connection and also marks the traffic in order to pass from certain priority queues (to provide guaranteed bandwidth). It also enables traffic engineering characteristics in order to provide load balancing on the network as well as fast rerouting in case of link failure. In addition we implemented a management tool for the service. The scope of this tool is to allow the users to manage their MBS requests (make a new one, edit, delete or view a request). Also the tool performs admission control and produces the necessary configuration that must be applied on the network in order to implement every service's request.

Different MCR approaches that include a static approach and dynamic approaches can be used for the MCR DiffServ system. We extend the OSPF protocol in order to build up more than one routing table in each MCR DiffServ system.

Most of recent research works have only focused on the individual layer issues and ignore the importance of interworking between different layers in a sensor network. In this paper, we use a cross-layer approach to propose an energy-efficient sensor network - CoLaNet, which takes (a) the characteristics and requirements of the applications, (b) routing in the network layer, and (c) the data scheduling in MAC layer into consideration. Specifically, we use the characteristics of the applications to construct the routing tree and then formulate the routing and MAC issues into a vertex-coloring problem. By solving that problem, CoLaNet is able to determine the proper data transmission schedule for each sensor node. We evaluate CoLaNet through extensive simulations and the results show that such cross-layer approach is energy-efficient and able to achieve significant performance improvement as well.","PeriodicalId":255955,"journal":{"name":"2005 Systems Communications (ICW'05, ICHSN'05, ICMCS'05, SENET'05)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132722081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
