Cost evaluation on secure routing over powerlines for WMNs

In Wireless Mesh Networks (WMNs), wireless nodes exchange routing messages among themselves to build routing tables. Since routing messages are sensitive and critical information, they should be kept confidential and protected. However, the existing WMNs convey the routing messages in an open medium (air) where the messages can be accessed publicly. By abusing the messages, attackers could launch various kinds of attack such as black hole, wormhole, reply, denial of services, and routing table poisoning. In this paper, we present a secure routing architecture for WMNs in which the routing messages are protected by making use of powerline as the routing medium. We also propose three routing protocols for the proposed architecture. The implementation costs of these protocols are evaluated under different scenarios.
