3 Vectors Game and Balance Multicast architecture Algorithms for Sensor Grid

We propose a scheme to reach shorter multicast delay, better energy utilizing efficiency and higher efficiency of data transferring for Sensor Grid. Our scheme calculates the space, energy and data weight vectors in one cluster. Then it searches a new vector composed by the linear combination of the three individual ones. We build game balance equation, use the equal correlation coefficient between the new and old vectors to find the point of game balance, seek linear parameters, and generate a least weight path tree. Extended simulation results indicate that our scheme attains less average multicast delay, the number of links used and better system robusticity.
