Abstract [en]

Wireless sensor networks and personal area networks are two relatively new and emerging technologies, capable of addressing a large number of applications such as home automation, medical monitoring, and sports monitoring. This article presents a new sensor network architecture suitable for emerging applications that require a highly mobile group of persons, such as fire fighters or assault teams, to be monitored in real-time. The architecture combines features from WSN, such as mesh routing and efficient communication, with the benefits of using a PAN architecture communicating with standardized Bluetooth profiles and the TCP/IP protocol suite. The use of Bluetooth enables the proposed architecture to use a user's mobile phone in order to achieve Internet connectivity, and IEEE 802.15.4 to create an internal mesh network. This dual-radio approach is necessary since today's mobile phones lack support for radio technologies traditionally utilized by WSNs. Performed tests indicate that the approach can support dependable delivery of sensor data to the Internet from a group of highly mobile users.

Abstract [en]

Recent developments in sensor technology have resulted in the feasibility of deployingsensors on a human user in order to sense physiological properties such as body temperature,pulse and posture. This enables monitoring of a user’s health condition and stresslevels.Some professions, such as first responders, are often operating in dangerous situations,which causes increased stress levels. Since stress can lead to poor performance with injuryor even death as a result, it would be very beneficial to remotely monitor the personnelto find those with critical body status and evacuate them from the dangerous area. Thiswould increase work safety and also allow for more efficient training. Another categoryof potential users for remote monitoring of health conditions are patients and elderly,who could enjoy a higher quality of life with the increased safety of remote monitoring.As a result, it is highly motivated to find a technology which is applicable for monitoringboth a number of collaborative users, i.e., a team, and as well as a single user. Oneinteresting solution is to use a wireless sensor network (WSN). Another technology forremote monitoring is a personal area network (PAN). A PAN usually consists of consumerdevices, which enables it to communicate with existing infrastructure networks throughthe use of standardized protocols and technologies.This thesis investigates the feasibility of using a heterogeneous sensor network architecturefor the remote monitoring of a group of highly mobile users. The architecture is acombination of a WSN and PANs, which benefits from the mesh networking capabilitiesin WSN and the support for standardized protocols in PAN. The usage of the WSNincreases the network reliability and provides mobility and additional service (e.g. localization)to each user. The wearable PANs provide infrastructure network access pointsto sensor nodes, and hence support the mobility of the entire sensor network (by reusinguser’s mobile phone). Experimental results show that the proposed network architectureis a competitive solution for the targeted application, and I believe that this researchwork has the potential to drastically improve the life quality of a very large number ofusers, such as elderly and patients.

Abstract [en]

This paper presents experimental results of a heterogeneous sensor network architecture, which is a combi-nation of a wireless sensor network and a personal area network. The proposed architecture uses the IEEE 802.15.4 standard to transmit sensor data to a sensor node which in turn forwards the data using TCP/IP to a database on the Internet via a Bluetooth-equipped mobile phone and the mobile telephone access network. The performance of the entire communication chain is evaluated. First, a 3G network's performance is evalu-ated by measuring its round trip time for packet transmission. Second, the real-world end-to-end delay be-tween a sensor node and a database server on the Internet is measured using two different experimental set-ups: single-hop transmission and two hops transmission. Finally, the proposed architecture's scalability is estimated in a Matlab simulation using the results of the experiments as a base. The results show that the proposed architecture is applicable for small-scale sensor networks used by highly mobile users.

Abstract [en]

In this paper, we investigate the performance of cluster-based localization using received signal strength indicator (RSSI). The proposed solution is designed to meet the requirements of monitoring of firefighters or similar applications. The empirical relationship between signal strength and distance is determined using experiment data. One of the most popular localization algorithms found today, Min-Max, is used for our testbeds. Our solution is implemented in TinyOS and experimentally evaluated on a Mulle v5.2 IEEE 802.15.4 platform. The aim of our research is to develop a heterogeneous wireless sensor network consisting of inter connected body area networks, or clusters. Using localization, the network's robustness and reliability, as well as the safety of its users, can be improved.
