A Survey on Security Techniques in Group Communication for Wireless Sensor Networks
A wireless network is a type of network where various physical devices (e.g. computer, laptops, PDAs etc.) are interconnected with each other using network infrastructure. Owing to wireless medium of data communication, the security risk is potentially high for unauthorized access and intrusion of various malicious programs. The security protocols of wireless network are governed by family of IEEE 802.11 standards. Wireless network is studied in research with respect to wireless LAN (Local Area Network), wireless mesh network, wireless sensor network, mobile ad hoc network, etc.
