Covert Channels in Ad-hoc Wireless Networks
A review of: Song Li; Ephremides, A., A Network Layer Covert Channel in Ad-hoc Wireless Networks, IEEE SECON 2004, October 2004. The paper by Li and Ephremides analyzes ad-hoc wireless network routing protocols for susceptibility to insertion of hidden communication channels. The paper focuses on a routing protocol called Ad-hoc On-demand Distance Vector (AODV). AODV [...]

Denial of service in sensor networks
A review of: Wood, A. D., and Stankovic, J. A. Denial of service in sensor networks. IEEE Comput. (2002), 54–62. http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=1039518 Wood and Stankovic analyze potential denial of service (DoS) attacks against wireless sensor networks and some strategies that have been used to mitigate this risk. Attacks are possible at each layer of the network [...]
