In recent years, human activity recognition (HAR) has gained importance in several domains
such as surveillance, recognizing indoor and outdoor activities, and providing active and …

Ubiquitous Life Care (u-Life care) is receiving attention because it provides high quality and
low cost care services. To provide spontaneous and robust healthcare services, knowledge …

We present a fully self-organizing approach for creating and maintaining a reference
coordinate system for self-localization in Sensor and Actor Networks (SANETs). GPS …

A great deal of research achievements on localization in wireless sensor networks (WSNs)
has been obtained in recent years. Nevertheless, its interesting challenges in terms of cost …

Self-organization is critical to enable novel indoor Location-Based Services (LBSs) for users
and businesses in large, complex and unstructured buildings. Inspired by high densities of …

In Wireless Sensor Networks (WSNs), localization algorithms could be range-based or
range-free. The Approximate Point in Triangle (APIT) is a range-free approach. We propose …

The proliferation of smartphones nowadays has enabled many crowd assisted applications
including audio-based sensing. In such applications, detected sound sources are …

Bluetooth Low Energy (BLE) devices such as iBeacons have been popularly deployed for
Location Based Services (LBS), including indoor infrastructure monitoring, positioning, and …

We present and discuss the autonomous localisation framework (ALF), a self-organising
indoor localisation environment. Location awareness is an important property for a growing …

A computationally valid shape model has been sought so that we can share shapes among
varied applications for extensive reuse. Current shape models are targeted at presentations …
