Locating Mobile Users Using Base Stations of Cellular Networks

Locating Mobile Users Using Base Stations of Cellular Networks

The location of mobile users served by cellular networks is considered. The chosen approach assumes that location is estimated through angular triangulation with three base stations (BSs). New estimates are proposed, which are described by closed-form expressions, and are alternatives to the maximum likelihood estimate. It is shown that the accuracy of the estimate coinciding with incircle cent...

Locating Base Stations for Mobile Servers

In this paper we review location models, specifically covering location models, which are applicable to modeling the location of base stations for cellular phone users. The definition of cover is revisited, suggesting three new definitions of cover: two gradual cover models, and one sum cover model. A new objective for covering models, the variable radius model, is proposed. The probability tha...

Locating Base-Stations for Video Sensor Networks

For a wireless video sensor network (WiViSeN) where video nodes have been placed at some strategic locations to capture designated scenes, an immediate challenge is to locate the base-station optimally such that the network lifetime of batterypowered video nodes can be maximized. This paper presents two schemes, one centralized and the other distributed, to obtain the optimal base-station locat...

Base Stations in Mobile Ad-Hoc Networks

Multi-hop ad-hoc networks consist of nodes which cooperate by forwarding packets for each other to allow communication beyond the power range of each node. In pure ad-hoc networks, no additional infrastructure is required to allow the nodes to communicate. Multi-hop hybrid networks are a combination of ad-hoc and cellular networks. As in ad-hoc networks, the nodes forward packets on behalf of o...
