It has been known for over one hundred years that radio can be used to keep in touch with people on the move. However, wireless communications using radio were not popular until Bell Laboratories developed the cellular concept to reuse the radio frequency in the 1960s and 1970s [31]. In the past decade, cellular communications have experienced an explosive growth due to recent technological adv...

Cellular networks provide voice and data services to the users with mobility. To deliver services to the mobile users, the cellular network is capable of tracking the locations of the users, and allowing user movement during the conversations. These capabilities are achieved by the location management. Location management in mobile communication systems is concerned with those network functions...

In the Mobile IPv6 protocol, the mobile node sends binding updates to its correspondents to inform them about its current location. It is well-known that the origin of this location information must be authenticated. This paper discusses several threats created by location management that go beyond unauthentic location data. In particular, the attacker can redirect data to bomb third parties an...

Pervasive systems require context awareness in order to be able to provide “anywhere, anytime” computing to mobile users. One type of context information is location information: pervasive systems require knowledge of the location of users, devices and services. This paper reviews location management for pervasive systems. The review is based on our experience in the development of a location m...

Personal Communication Systems (PCS) maintain a Location Management mechanism for tracking the location of their mobile users. The increasing population of mobile users leads to congestion problems in these systems, and motivates the development of more efficient management schemes. This work presents a new mobility management scheme that integrates the location area approach with the location ...

This comprehensive work explores the research performed inoptimization of the collection bin and in recycle bin location-allocation issues in solidwaste management. Although the collection phase of solid waste management accountsfor a significant proportion of the municipal budget, it has attracted only limitedattention of the researchers. Optimization of the collection bin and recycle bin loca...

요 약 Mobile computing is very important in location management 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 hierarchica...

The growth of cellular users using to communicate at any place and any time increases the signaling activities among the cellular networks. To reduce the network costs and better usage of radio resources, an efficient location management scheme: location updating and paging strategies are essential to improve the network performance. This paper presents a mixed location management strategy that...
