Wireless Mesh Network (WMN) is a network of network and heterogeneous in nature. Due to its heterogeneous nature and openness, it is more severe to attacks. There are multiple points over which an attacker can easily attacked. Many security techniques have been proposed up to now for WMN. Virtual Private Network (VPN) provides security by creating ownership of client over network by creating virtual tunnels over the network between clients. But traditional VPN is unable to provide all security features. Now-a-days', MPLS provides traffic engineering features with the VPN and provides more security features and faster traffic rerouting. But many attacks have their impact over these security techniques.
