In this paper, a new approach is proposed to estimate the location of a sensor in a wireless
sensor network. For the estimation, only a few anchor nodes with known locations and …

In this paper, we introduce a cross-layer, application-oriented communication protocol for
Wireless Sensor Networks (WSN). TSTP-Trustful Space-Time Protocol-integrates most …

Currently, there are various works presented in the literature regarding the activity
recognition based on WiFi. We observe that existing public data sets do not have enough …

It is a mistake to assume that each embedded object in the Internet of Things will implement
a TCP/IP stack similar to those present in contemporary operating systems. Typical …

In many applications of wireless sensor networks, location is very important information. It
can be used to identify the location at which sensor readings originate, in routing and data …

Architectural restrictions of scan greatly limit the effectiveness of traditional scan based delay
tests. It has been recently shown that additional testing for delays on short paths using fast …

Localization technology is one of the key supporting technologies in wireless sensor
networks. In this paper, a two-hop collaborative multilateral localization algorithm is …

In many applications of wireless sensor networks, location is very important data. Location
data can come from manual setting or GPS device. However, manual setting requires huge …

Accurate, distributed localization algorithms are needed for large scale dense wireless
sensor network applications. The Nelder-Mead Simplex Optimization Method (SOM) is …

The objective of this dissertation is to estimate the location of a sensor through analysis of
signal strengths of messages received from a collection of mobile anchors. In particular, a …
