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...

Risk assessment of central water supply systems a case study. This paper presents methods for identification and risk assessment of central water supply systems, exemplified by a case study of the central water supply system in Luna locality, Cluj county during 2009-2010. System assessment was performed by means of previous data on water quality monitoring and water samples analysis for the par...

nowadays, with population growth in urban areas, providing safe water and health is considered basic needs of human, alongside the various pollutants due to urban activities, agriculture and industrial areas on adjacent ranges into urban water resources around the environment is such that study necessary to prevent the pollution of water resources and identification of pollution sources shows. ...

a Wireless Sensor Network is collection of sensor nodes organized in co- operative way. In node each has sensing, communication and computational capabilities. can be deployed throughout physical space, providing dense sensing quite close to phenomena. this paper there review on WSN challenges realistic situations where face the problems deployment, energy consumption, & routing protocols n...

Due to the abilities of real-time sensing and information sharing, Wireless Sensor Network (WSN) has been applied in more and more fields. Basing on the emergence of Internet of Things (IoT), the issue about heterogeneous network integration is becoming more important. We first analyze the new businesses that arise recently for cell phone users as well as the potential effect on carrying networ...

Recently, Wireless Sensor Network has captured the attention of academic and industrial research communities. One of the reasons is that Wireless Sensor Network has diverse applications and domains such as environment protection, battlefield monitoring, traffic control, etc. The central problem of a Wireless Sensor Network is the Coverage Problem that poses the question of how the set of sensor...
