Many existing PC power saving features are under utilized since they may interfere with users’ normal operations of computers. By taking into consideration the locations of computer users, locationaware PC power management techniques can overcome such limitations and offer both energy savings and non-intrusiveness. However, existing locationaware power management schemes either rely on complex ...

EEective management of battleeeld networks requires a hierarchical network management architecture wherein managers can dynamically delegate management tasks to intermediate managers. In this paper we describe a novel framework called SHAMAN-Spreadsheet-based Hierarchical Architecture for MANagement-which extends the traditional at SNMP management model to a hierarchical architecture. We descri...

The Mobile IP Standard has been developed to support mobility over the Internet. This standard contains several drawbacks as in the cases where packets are routed via sub-optimal paths and significant amount of signaling messages is generated due to the home registration procedure which keeps the network aware of the current location of the mobile nodes. Recently, a dynamic hierarchical mobilit...

This paper presents a “flat” mobile location management scheme for Personal Communication Networks (PCNs) with the goal of reducing both mobile tracking and location costs. Mobile tracking costs are reduced by the use of one-level tracking for mobiles in their “home area”, and a two-level tracking approach for mobiles visiting other areas. Mobile location costs are reduced by using an improved ...

Reducing the cost of dynamic mobility management in wireless communication networks has been an interesting and important issue. It is well known that by using a selective paging method, both costs for location update and terminal paging can be reduced significantly. However, an efficient selective paging method needs the information of the location distribution of a mobile terminal. Based on o...

The combination of peer-to-peer systems and ad-hoc networks allows for the creation of highly dynamic, self-organizing, mobile P2P systems. By taking advantage of location information, a routing protocol in these systems can aid the mobile hosts to efficiently communicate with each other. There is a need therefore for highly scalable location management systems that can provide location informa...

요 약 Location management is very important in location based services to provide services to the mobile users like banking, city guides and many more. Ubiquitous and mobile devices are the source of data in location management and its significant operations are update and search method. Some studies to improve these were presented by using optimal sequential paging, location area scheme and hier...

An important issue in the design of mobile computing systems is the efficient management of location information. In this paper, we propose the Legion structure that can be used to construct schemes for distributed applications, such as location management, information dissemination, mutual exclusion, etc. We also present a new and simple distributed quorum-based location management scheme, Leg...

To conceive the full potential of ubiquitous mobile computing, mobile nodes must be able to roam seamlessly across different networks. However, the location i.e. IP address, of a called mobile nodes must be determined within a certain amount of time, before the services are blocked. With the upcoming 3G, 4G and wireless LAN technologies, it is necessary to have an efficient location management ...

The ITU’s choice of ATM as a reference implementation of B-ISDN networks strengthened by the combination of legacy protocols over ATM as the foundation of the new very-high-performance Backbone Network Service (vBNS) show the significance of this particular network technology in the future. Besides, the international telecommunication industry tends more and more to integrate wireless and wirel...
