The advances in wireless networking have enabled new paradigms in computing. An
abundance of information and services provided by remote servers is expected to become …

Position-based ad hoc routing algorithms have proved to have decent performance in
delivery ratio and end-to-end delay. Position service is essential for such algorithms. In this …

Location services are used in mobile ad hoc and hybrid networks either to locate the
geographic position of a given node in the network or for locating a data item (content). One …

In ad-hoc networks, geographical routing protocols take advantage of location information
so that stateless and efficient routing is feasible. However such routing protocols are heavily …

With the fast growing uses of GPS-equipment, mobile users can more easily determine
where they are located. These physical location information may play an important role in a …

The advent of light-weight terminals (eg, PDA) with integrated communication capabilities
facilitates service access and hosting anytime, anywhere. However, effective service access …

Localization is an important process in deploying ad-hoc wireless sensor networks. Several
localization algorithms have been developed. However, they do not achieve satisfactory …

We propose a method to estimate the location of a mobile user. We assume that mobile
users carry portable devices such as laptops or personal digital assistants equipped with off …

A mobile ad hoc network (MANET) consists of a set of mobile hosts that do not need a base
station. Due to the high mobility of nodes, the network topology of MANETs always changes …

Position-based routing has proven to be a scalable and efficient way for packet routing in
mobile ad-hoc networks. To enable position-based routing, a node must be able to discover …
