A distributed algorithm based on probability for refining energy-efficiency of multicast trees in ad hoc networks

A distributed algorithm called P-REMiT is proposed for building an energy-efficient multicast tree in ad hoc networks. The P-REMiT uses the probability method to balance the total energy consumption (TEC) and system lifetime (SL) of multicast tree. It gets the better performance than S-REMiT on metrics about system life and also obtains the better performance than L-REMiT on metrics about TEC. It improves SL of multicast tree efficiently with little sacrifice on TEC and has good convergence.
