In general Mobile Ad-hoc NETworks (MANETs) employ conventional routing algorithms like Ad-hoc On-demand Distance Vector (AODV) routing to forward data. But these algorithms cannot be used effectively in a network environment where the number of malicious nodes is high. This scenario causes high delay and loss of data. To detect and eliminate such nodes this paper proposes a unique trust based routing algorithm where the next hop forward node is selected based on the ability of a node to deliver data. This ability is numerically quantified as trust rating and is used to compare various nodes based on this parameter before forwarding data to it.
