Almost all the research papers published have different algorithms for trust calculation. Therefore, the framework has allowed any trust calculation algorithm to work by simply defining how the calculation should work.

	~~By default, there~~ is ~~a generic~~ trust calculation ~~defined in~~ <code>~~abstract-~~trust-~~calculation.h~~</code>. ~~Users can extend that~~ class ~~and define their own algorithm~~.		<code>simple-aodv-trust-handler</code> is proper example usage of trust calculation of the trust framework. <code>trust-handler</code> is the abstract class which has <code>CalcuateTrust()</code> method. This method must be implemented in a concrete class.

	Trust value will be calculated based on different routing parameters''(rreq, rply, err, etc)'' or routing metrics''(bandwidth, cost, etc)''. Therefore, trust will become a routing metric which can be used to determine the optimal route for forwarding packets. Eventually trust value can be considered as a security factor for making the routing decision.

	'''Default trust calculation''' in the framework has only considered ''interaction count.'' If someone wants to consider more parameters''(rreq, rply, err, etc)'' for trust calculation, trust table can be modified accordingly.
