Abstract :
Multicast is an important communication mode in wireless ad hoc networks. Furthermore, an adaptive antenna array with multiple-input-multiple-output (MIMO) channel model is more suitable for wireless multipath environments. In this paper, we study energy efficient one hop multicast in such an environment. The problem is formulated as a non-linear programming problem and two heuristic algorithms are proposed to solve the problem.
