A Power Efficient Solution to Counter Blackhole and Wormhole Attacks in MANET Multicast Routing

Abstract

Routing is of prime importance in mobile ad-hoc networks as it is complex and the environment is extremely dynamic. On the other hand, multicast routing supports one to many communication and it is efficient with channel usage, bandwidth. Routing algorithms define how data travels in a multicast network. In this paper we take a close look at attacks in multicast networks and ponder up on techniques involved in making the operation secure. Power usage should be kept an eye on, as multicasting involves nodes operating at remote locations. The power consumption was made aimed to make as minimal as possible. Mobile ad-hot networks are complex environments that are extremely dynamic. Routing is the first step in setting up a MANET and it is of paramount importance to do it securely and efficiently. Many algorithms have been proposed to secure the routing. However, the operation is still a grey block with multiple major security challenges. In this paper we take a deeper look at techniques in making more robust and secure.
