چکیده
This paper describes an extensible simulation environment for the modeling of wireless sensor networks (WSNs). In particular, our simulator facilitates the study of secure connectivity between sensor nodes. The simulator has five main components: network topology model, key establishment protocol, adversary model for node capture, network analysis tools, and a graphical user interface (GUI) to facilitate rapid simulation, visualization, and analysis of WSNs. We present the design and implementation of our simulation tool, including the methodologies and algorithms underlying each component, and the data flow dependencies between them. Additionally, we describe the data collection and analysis functions integrated within the simulator, and how these can be used for in-depth simulation studies. We have used the simulator to verify asymptotic analytical results for secure WSNs, as well as to investigate their structural characteristics. We present selected results to demonstrate the use and value of our simulation tool.

Unauthenticated event detection in wireless sensor networks using sensors co-coverage
Wireless Sensor Networks (WSNs) offer inherent packet redundancy since each point within the network area is covered by more than one sensor node. This phenomenon, which is known as sensors co-coverage, is used in this paper to detect unauthenticated events. Unauthenticated event broadcasting in a WSN imposes network congestion, worsens the packet loss rate, and increases the network energy con...

A sensor node is composed of different parts including processing units, sensor, transmitter, receiver, and security unit. There are many nodes in a sensor unit. These networks can be used for military, industrial, medicine, environmental, house, and many other applications. These nodes may be established in the lands of enemies to monitor the relations. Hence, it is important to consider conse...
متن کاملA Fuzzy Based Approach for Rate Control in Wireless Multimedia Sensor Networks
Wireless Multimedia Sensor Networks (WMSNs) undergo congestion when a link (or a node) becomes overpopulated in terms of incoming packets. In WMSNs this happens especially in upstream nodes where all incoming packets meet and directed to the sink node. Congestion in networks, if not handled properly, might lead to congestion collapse which deteriorates the quality of service (QoS). Therefore, i...
متن کاملAn efficient symmetric polynomial-based key establishment protocol for wireless sensor networks
An essential requirement for providing secure services in wireless sensor networks is the ability to establish pairwise keys among sensors. Due to resource constraints on the sensors, the key establishment scheme should not create significant overhead. To date, several key establishment schemes have been proposed. Some of these have appropriate connectivity and resistance against key exposure, ...
