Experimental Comparison of Algorithms for Energy-Efficient Multicasting in Ad Hoc Networks

Energy is a scarce resource in ad hoc wireless networks and it is of paramount importance to use it efficiently when establishing communication patterns. In this work we study algorithms for computing energy-efficient multicast trees in ad hoc wireless networks. Such algorithms either start with an empty solution which is gradually augmented to a multicast tree (augmentation algorithms) or take as input an initial multicast tree and ’walk’ on different multicast trees for a finite number of steps until some acceptable decrease in energy consumption is achieved (local search algorithms).
