Energy consumption is considered as a critical issue in wireless sensor networks (WSNs). Batteries of sensor nodes have limited power supply which in turn limits services and applications that can be supported by them. An efcient solution to improve energy consumption and even trafc in WSNs is Data Aggregation (DA) that can reduce the number of transmissions. Two main challenges for DA are: (i)...

Modern system identification (SID) procedures rely on fixed sensor networks for data collection. Ideally, sensors are fixed at locations and contain profitable structural responses, however, such sensing areas are often limited by the accessibility of the structure and environmental hazards. Not only are fixed sensor placements limited, the data contains restricted spatial information. Mobile s...

We present an experimental mobile platform which can drop self contained sensor nodes to deploy a Wireless Sensor Network (WSN). At the same time, this network can be used to increase the operation range of the mobile platform.

sybil attacks pose a serious threat for wireless sensor networks (wsn) security. they can create problems in routing, voting schemes, decision making, distributed storage and sensor re-programming. in a sybil attack,the attacker masquerades as multiple sensor identities, that are actually controlled by one or a few existing attacker nodes. sybil identities are fabricated out of stolen keys, obt...

In wireless sensor networks (WSNs), the sensor nodes transmit critical information over the network. Therefore security services such as authentication and pair wise key establishment between sensor nodes and mobile sinks are important. However, the problem of authentication and pair wise key establishment in sensor networks with mobile sinks is still a critical problem in the face of mobile si...

Wireless sensor network can be used in military application for monitoring militant activities like tracking enemies, force protection and monitoring the vital signs of the soldiers who are in a battlefield. Wireless sensor network has set of distributed sensor nodes which are connected to each other. These sensor nodes are low powered, low cost, small in size with limited amount of battery sup...

The wireless sensor network is used to solve problems in real world such as industrial and environmental Sensing. There are two types of Wireless Sensor Network, Mobile and Static. They are the Wireless Sensor Network are prone to attacks. The most prominent attack in Wireless Sensor Network is node replication attack were the nodes are replicated virtually. The replicated node captures the key...

Due to resource constraint nature of sensor nodes, the network suffers by computation and security problems. These nodes create a wireless sensor network that used sink stable or mobile as per required applications. Therefore, various traditional security techniques of the traditional networks are not possible to be applied on this network. To overcome the security problem in this ad-hoc or wir...

In wireless sensor networks (WSN), there are many nodes and they are unattended so an adversary can easily capture and compromise the sensor nodes and take secret key from the nodes then make many replicas (duplicate) of them. After getting the secret key from the sensor node the sensitive data which is present in the nodes get leaked so an adversary can quickly degrades the network communicati...

The introduction of mobile devices into wireless sensor network systems has attracted significant attention in recent years. Mobile devices can provide a bridging mechanism to connect geographically separated sensor networks, forming a global coverage sensing network. However, effective techniques for organizing multiple mobile devices and supporting coordinated sensor-data sharing have not yet...
