  The mobile ad-hoc network consists of energy constraint devices called nodes
communicating through radio signals forming a temporary network i.e. nodes are
continuously switching from one network to another. To minimize the power
consumption, we form the clusters with an elected cluster head (Service
Provider) based on any cluster head selection strategy.To establish a trusted
link amongst newly entered node and CH we have adopted an indirect trust
computation technique based on recommendations, which form an important
component in trust-based access control models for pervasive environment.In
this paper, we shall present some existing indirect trust based techniques and
subsequently discuss our proposal along with its merits and future scope.
