An improved trust calculation method for mobile Ad Hoc Network

Securing a Wireless Ad Hoc Network is one of the major concerns for the researchers. Due to wide-ranging characteristics of the ad-hoc networks, it is always at a risk to internal as well as external attacks. Many solutions have been proposed and currently being improved in this area. Most of these solutions involve encryption, secure routing, quality of service etc. Each of them is designed to operate in a particular situation, which may fail to work successfully in other scenarios. This paper offers an alternate approach to improve the trustworthiness of the neighbourhood nodes and secure the routing procedure. It helps in computing the trust in neighbours and selecting the most secured route from the available ones for communication. It also helps in detecting the compromised node and virtually removing from the network.
