CloudConsumerism: A Consumer-Centric Ranking Model for Efficient Service Mapping in Cloud

Algorithm 1

Service mapping algorithm.

Input: Directory of CSPs and Consumers.

Output: Service mapping of CSPs and Consumers.

Begin

 For all the available CSPs set flagCSP ←1.

  IF CSPs ==1 && consumers ==1 THEN

   bind consumer to CSP

   flagCSP ←0.

  END IF

  IF CSPs >1 && consumers ==1 THEN

   get the ranking score of the CSPs using TOPSIS;

   sort the ranking score of CSPs and find top rank CSP;

   map the consumer to CSP;

   flagCSP ← 0;

  END IF

  IF CSPs ==1 && consumers > 1 THEN

   get the ranking score of consumers using TOPSIS;

   sort the ranking score of consumers and find top rank consumers;

   map the consumer to CSP;

   flagCSP ← 0;

  END IF

  IF CSPs >1 && consumers > 1 THEN

   FOR each consumer DO

    get the ranking score of CSPs using TOPSIS Method;

    sort the ranking score of CSPs and find top rank CSP;

   END FOR

   FOR each CSP DO

    get the list of competitive consumers;

   END FOR

   FOR each CSP DO

    IF competitive consumers list is empty THEN

     continue;

    ELSE IF competitive consumers ==1 and flagCSP ==1 THEN

     map the consumer to CSP;

     flagCSP ← 0;

   END IF

   ELSE flagCSP ==1 THEN

    get the score of competitive consumers using TOPSIS;

    rank the consumers and get the top rank consumer;

    map the consumer to CSP;

    flagCSP ← 0;

   END FOR

  END IF

  After completion of the service the flagCSP is set to 1;
