Stable Energy-Efficient Position-Based Multicast Routing (SE2PBM) in Mobile Ad hoc Networks

In this paper, the problem of energy efficient multicasting in mobile ad hoc networks is tackled with incorporation of minimum required stability along each path. A novel model is presented to compute the stability of links as a function of transmission power of forwarding nodes and mobility history of links. We present a mixed integer programming model which can be used for an optimal solution of the minimum energy multicast routing with stable paths in mobile ad hoc networks. Further, we propose a source-initiated distributed heuristic position-based multicast routing algorithm (SE²PBM) to construct minimum energy consumption multicast trees in mobile ad hoc networks. SE²PBM selects transmission power level of forwarding nodes in order to guarantee certain stability requirement, while minimizing total energy cost. Simulation results are presented which supports our approach.
