This survey provides a technology overview and review of existing literature of visible light communication and sensing and outlines important challenges that need to be addressed in order to design high-speed mobile networks using visible light Communication-VLC. Expand
Medium access control in wireless sensor networks
This work presents a discussion of medium access control concepts in relation to sensor networks and examines previous wirelessMedium access control protocols are examined to illustrate how they do not match the requirements and characteristics of sensor networks. Expand
Power conservation and quality of surveillance in target tracking sensor networks
This study quantifies the trade-off between power conservation and quality of surveillance while presenting guidelines for efficient deployment of sensor nodes for target tracking application. Expand
FIREMAN: a toolkit for firewall modeling and analysis
Fireman, a static analysis toolkit for firewall modeling and analysis, is introduced and used to uncover several real misconfigurations in enterprise networks, some of which have been subsequently confirmed and corrected by the administrators of these networks. Expand
WiWho: WiFi-Based Person Identification in Smart Spaces
WiWho is presented, a framework that can identify a person from a small group of people in a device-free manner using WiFi and it is shown that in most cases walking as few as 2-3 meters is sufficient to recognize a person's gait and identify the person. Expand
Trust Computations and Trust Dynamics in Mobile Adhoc Networks: A Survey
A detailed survey on various trust computing approaches that are geared towards MANETs is presented, including trust propagation, prediction and aggregation algorithms, the influence of network dynamics on trust dynamics and the impact of trust on security services are analyzed. Expand

The proposed QRON algorithm adopts a hierarchical methodology that enhances its scalability and simulated the protocols based on the transit-stub topologies produced by GT-ITM, showing that the proposed algorithms perform well in providing a QoS-aware overlay routing service. Expand
An analytical model for the energy hole problem in many-to-one sensor networks
In a many-to-one sensor network, all sensor nodes generate CBR data and send them to a single sink via multihop transmissions. Sensor nodes sitting around the sink need to relay more traffic andExpand
Efficient overlay multicast for mobile ad hoc networks
A novel source-based Steiner tree algorithm is proposed for constructing the multicast tree that gradually adapts to the changes in underlying network topology in a fully distributed manner. Expand
