Fuzzy-Based Trust Prediction Model for Routing in WSNs
Algorithm 1
Algorithm for processing TREQ and TREP.
| (a) Algorithm for transmitting TREQ message | | Subject broadcasts the following TREQ message to its neighbors in its transmission range | | | where S and T be the subject and target respectively. | | Subject waits for recommendation messages until a predetermined time. | | (b) Algorithm for processing the TREQ message | | Neighbor receives the TREQ message broadcast by the subject | | if (TReqId is new and not processed earlier) | | checks its trust table for trust relationship with target | | if ( is available in the transaction table) and (number of recent | | transactions ≥) then | | unicasts the TREP message to S | | | | else | | discards the TREQ packet | | end if | | else | | discards the TREQ packet | | end if |
