Location aware end-end data security using mac for secured wireless sensor networks

Data security in wireless sensor networks include data authenticity, data confidentiality and data availability. Providing desirable data security in wireless sensor networks is a challenging one since wireless sensor networks consists of large number of sensor nodes that are generally placed in hostile or unattended environments which may be exposed to several attacks. Attacks due to node compromise include Denial of service attacks such as selective forwarding attacks and report disruption attacks.
