Emergency Crowdsourced Automated Adaptive Networking System

EmergencySafety and security are major requirements for any community. These criteria in the past have been granted through the work of emergency first respondents whose work relies on accuracy and efficiency. A misevaluated incident could escalate into a larger situation leading to critical events with greater consequence. Therefore to combat this problem accurate information needs to be passed to the right personnel to ensure appropriate measures are taken. This is in fact the weakness of the first response system. Citizens who are often caught in crisis situations are required to relay information to emergency officials to allow for aid. The issue being that under increased stress and danger citizens often struggle to give an accurate account of the situation.

Our Emergency Automated Adaptive Networking System allows for simple live streaming from a citizen's smart device directly to a first response system. This serves to alleviate the pressure from the individual allowing for a more accurate solution for information transfer. Once information is received along with relevant GPS information, respondents can then act accordingly.

Community Trsut Distribution in Vehicle Ad-hoc Networks

VANETVehicular Ad-hoc Networks (VANETs) have attracted much research and community attention recently due to the benefits that can be provided though this technology. For instance, communication between vehicles can help make the roadway a safer place, where vehicles can work together to share information about road conditions.

As vehicles are equipped with the ability to communicate, the need to develop trust between vehicles is crucial. Trust is referred to as the ability of an agent to accept, with confidence, information from another vehicle (agent). If messages are not trustworthy, then communication between any given agents is futile.

Cluster-Based Dynamic Backup in Cognitive Radio Networks

VANETRecent years have shown an increase demand for wireless communication which creates new challenges in the field where intelligent spectrum utilization is necessary to maintain high network performance. The emergence of Cognitive Radios which provide opportunistic access to the spectrum, introduce an improvement in the spectrum utilization and the communication quality. Through dynamic spectrum access (DSA), secondary (un- licensed) cognitive users can opportunistically access the primary users’ spectrum when it is free, but have to release the undesig- nated spectrum when the primary users emerge to provide reliable and efficient communications through the network. To maintain the highest level of quality of service among all the network users (primary and secondary) and to avoid any interruptions occurred by the primary users needed to use their licensed spectrum, we, in this work, aim to introduce a hybrid scheme in which the secondary users find options for a backup path, but they only solidify that path if they must vacate their original path. Our numerical results showed that through our proposed scheme, we were able to enhance the goodput and provide a higher satisfied ratio through dynamically backing up secondary users requests.
