Abstract:

MANET routing is critical and routing decision should be made sooner before the node leaves the network. Fast decisions always compensate network performance. In addition, most MANET routing protocols assume a friendly and cooperative environment, and hence are vulnerable to various attacks. Trust and Reputation would serve as a major solution to these problems. Learning the network characteristics and choosing right routing decisions at right times would be a significant solution. In this work, we have done an extensive survey of fault tolerant protocols and ant colony algorithms applied to routing in MANETs. We propose a QoS constrained fault tolerant ant lookahead routing algorithm which attempts to identify valid route and look-ahead route pairs which might help in choosing the alternate path in case of valid route failure. The results prove that the proposed algorithm takes better routing decisions with 20-30 percent improvement compared with existing ant colony algorithms.
