However, the number of IP addresses in IPv4 is estimated to be not enough in the near future. IPv4 has been thus switched with IPv6. Meanwhile, Network Address Translator (for short, NAT) has been used for solving the lack of the IP addresses. On the other hand, since a communication from the Internet to the private or home networks in NAT is difficult, many NAT traversal techniques have been developed as the solution. One of the NAT traversal techniques is that of \"relaying\". However, the relaying techniques have a drawback such that the relay server can be overloaded according to an increase in the number of communications. In this paper, as NAT traversal in a home gateway which is connected the home to the Internet, a scheme to balance the load by several relay servers and by a surveillance one is presented and two relay server selection methods are proposed. The proposed methods are a random selection and a priority-based one. Simulation results show that the load makes it possible to balance well in inverse proportion to the relay servers by the proposed methods.","PeriodicalId":143803,"journal":{"name":"2008 Australasian Telecommunication Networks and Applications Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125988074","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}

Since mobile devices have limited energy capacity, efficient use of the energy is indispensable for mobile P2P systems. In this paper, we propose an energy-efficient P2P system that is a type of the double-layered P2P systems in which files are searched mainly through the peers in the upper level, called super peers. The proposed system selects greedily the peers with more energy as super peers. The peers in the proposed system can identify themselves as super peers or sub-peers autonomously in a decentralized manner. We also propose three energy-efficient routing schemes, each of which is incorporated with the proposed system individually. The first routing scheme tries to utilize the energy of the peers on the routes more evenly, the second scheme chooses a route with the `strongest' peer among the peers each of which is the `weakest' peer on a route, and the last scheme selects a route with the second scheme among the routes with the smallest number of hops. Note that a routing scheme is applied each time when a route between a pair of super peers is chosen during the message transmission. Functionality and performances were evaluated through various experiments, and the results showed that the proposed P2P system with the third routing scheme improved the average network lifetimes by 368% and 22% over the double-layered and the proposed systems without applying any proposed scheme, respectively.","PeriodicalId":143803,"journal":{"name":"2008 Australasian Telecommunication Networks and Applications Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134581203","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}

There are still a lot of interesting problems investigating the capacity and the optimal design of these networks. This paper looks at one of these outstanding problems. Specifically the problem addressed is to determine how the capacity of a MANET can be increased by the optimal placement of an additional dynamic node in a power efficient manner. This node is envisaged to be a platform whose primary purpose is to increase the capacity and power efficiency of the MANET. Given a specific network configuration the optimal location of an additional node is investigated. This node insertion is teamed with power adjustments of all the nodes carried out in a manner consistent with topology control. This approach is then compared to topology control methods not using an additional node. The simulations performed show that the technique described can significantly decrease the jamming experienced within a MANET, thereby increasing the network's capacity. Additional benefit is also observed in the power usage of the MANET falling, thereby increasing the operational lifetime of the network. From the results obtained it will be inferred that a simple distributed algorithm to find the optimal point is not a trivial exercise.","PeriodicalId":143803,"journal":{"name":"2008 Australasian Telecommunication Networks and Applications Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134615313","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}
