Mobile Ad-hoc NETworks (MANETS) are vulnerable to malicious node attacks because they spoil the integrity of network by consuming network resources, dropping packets and false routing. Routing misbehavior can be avoided by following trusted path for data transmission. Existing Trust based mechanisms for secure routing increase overhead and complexity w.r.t processing and architecture. The authors compare multiple trust based secure routing techniques. The primary focus of this paper is to present an ad-on technique named 'Explicit No' with reduced complexity, for evaluating trust worthiness of a neighboring node.
