Cross-Layer Design for Energy-Efficient Secure Multicast Communications in Ad Hoc Networks

Abstract

The authors consider the problem of secure multicast in an energy-constrained wireless environment. They present an analytical formulation of the energy expenditure associated with the communication overhead of key management, and highlight its dependence on network topology and key distribution method. They show that the optimal solution of this formulation does not scale with multicast group size and propose a sub-optimal, cross-layer, low-complexity algorithm for energy-efficient key distribution. Simulation studies are presented to show the energy savings achieved by their scheme, and its performance is compared when different routing algorithms are employed (i.e., Broadcast Incremental Power (BIP), the Embedded Wireless Multicast Advantage (EWMA), the Minimum Spanning Tree (MST), and Shortest Path Routing (SPR)).
