— Wireless sensor networks (WSN) are used in a number of different applications including military, environment monitoring, smart spaces etc. Security is an important aspect in WSN, however given scare resources; implementing traditional cryptographic algorithms is not very well suited for WSN nodes. Hence watermarking is being investigated as an(More)
Wireless multimedia sensor networks (WMSNs) are an emerging type of sensor network which contain sensor nodes equipped with microphones, cameras, and other sensors that produce multimedia content. These networks have the potential to enable a large class of applications ranging from military to modern healthcare. Multimedia nodes are susceptible to various(More)
The function of Wireless Sensor Networks (WSNs) is to collect and store data sent to other nodes or servers. Current technologies allow validation during transit, but stop after the data reaches its destination. One of the challenges with these technologies is to ensure that the source of the data is preserved, once it leaves the WSN. This is important as(More)
In Wireless sensor networks (WSNs), All communications between different nodes are sent out in a broadcast fashion. These networks are used in a variety of applications including military, environmental, and smart spaces. Sensors are susceptible to various types of attack, such as data modification, data insertion and deletion, or even physical capture and(More)
