Advances in the Internet of Things (IoT) infrastructures are enabling the gathering, processing and inference of a wide array of data, enabling more agile decision management frameworks in several contexts, including vehicle routing and navigation. Coupled with crowd-sensing, these decision management frameworks gain further advantage in terms of data availability. This work concerns itself with safety...
Multi-standard mobile terminals (MTs) allow mobile users to experience ubiquitous connectivity and better quality of service. However, these advances come at a price of higher power consumption for MTs due to holding multiple active interfaces. In this paper, we apply multihop relaying through pervasive short range interfaces (e.g., Bluetooth, WiMedia. etc.) in the presence of an infrastructure network...
The next-generation mobile networks will be equipped with sophisticated communication security, ensuring the safety and authenticity of the transmitted information. However, many of today’s prominent security measures are cryptography-based and present several operational challenges in mobile computing systems. Thus, enforcing security measures can greatly affect communication performance, particularly,...
Knowing the position of sensor nodes in an environmental monitoring is useful to identify the location of events. However deploying GPS receivers or other anchor sensors is expensive, since the role of anchor nodes ends after localizing sensor nodes' positions and they are transferred into ordinary sensor nodes. In this paper, we introduce a new localization scheme for a wireless sensor network that...
Localization will play an important role in the Internet of Things (IoT), and will employ several complementary mechanisms, each applicable to Things with different characteristics. This paper investigates the impact of scale and mobility on wireless multi-hop localization mechanisms, which specifically target Things with limited capabilities inhibiting them for self-localization, i.e., cannot locally...
