Executive Summary

Wireless network is very susceptible to different types of attack. The main attack is Sybil attack, which allows forming other attacks on the network. Security is very important to the wireless network. In wireless sensor network, to verify node identities by cryptographic authentication but this is not easy because sensor node which contains limited resources. Therefore the current research is going on how to handling the situation of different traffic levels and transmission power for security.
