Modern society is surrounded by an ample spectrum of smart mobile devices. This ubiquity forms a high potential for community-oriented opportunistic ad hoc networking applications. Nevertheless, today’s smart mobile devices such as smartphones, tablets, and wristbands are still onerous to automatically establish mobile ad hoc connections with our physical circle of friends and between occasional contact...
This study introduces Oppline, an ad hoc opportunistic short message service that can be collaboratively used by everyone who has a smart mobile device. The data exchange method of Oppline is built on top of the universal Wi-Fi standard, thus expedites platform-independent integration of related mobile applications for delay-tolerant communications in public space. Even in highly-dense mobile networks...
This paper presents OBN, a universal opportunistic ad hoc networking model particularly intended for smart mobile devices. It enables fast and lightweight data dissemination in wireless community networks through the utilization of universally-available wireless network identifiers. As a ubiquitous alternative to the publicly-limited ad hoc networking interfaces, it resolves many of the peer-to-peer...
This study introduces an ad-hoc opportunistic data dissemination protocol, called VADISS, that facilitates participatory traffic monitoring applications with smartphones. As a ubiquitous alternative to existing vehicular networking methods, VADISS uses the default WiFi interfaces universally adopted by today's mobile devices. The routing is enabled with intermittent service advertisements and discoveries,...
We investigate QoS provisioning in a Wireless Activity Monitoring Network(WAMN) when data traffic is a mixture of emergency short voice commands and 3D accelerometer signals for remote monitoring of a group of elderly people living in a health care building. Nodes equipped with acoustic and accelerometer sensors form a multi hop wireless sensor network. The network carries multi class traffic to the...
Current trend in store-carry-forward fashioned opportunistic networks is towards utilizing social ties in communities. However, keeping social knowledge/network information up-to-date is a non-trivial task due to ever-changing dynamics such as mobility and other human behavior. Therefore, social-based message forwarding proposals in which network information are initially provided to mobile nodes...
Audio data processing and transmission in Wireless Sensor Networks (WSNs) require systems which satisfy the equilibrium between heavy data traffic and limited resources. In the lossy nature of the network, transmission techniques matter to sustain a certain content validity to be preserved. Besides, data handling is a worth-stressing issue to sustain a decreased computation and traffic overhead. An...
