Abstract
An efficient broadcast algorithm can significantly improve the resource utilization in an ad hoc network by decreasing the number of packet collisions and overall power consumption. However, the nature of ad hoc networks poses a challenging problem for creating an efficient broadcast algorithm. Recently a Gateway Multipoint Relays (GMPR) broadcast algorithm has been proposed, which integrates the Multipoint Relay (MPR) and the maximal independent set (MIS) concepts to construct a small size connected dominating set (CDS) in a network. In this paper, we present our enhance approach to the GMPR algorithm to further reduce the CDS size. The effectiveness of our approach is confirmed through simulations.
