Target Transmission Radius over LMST for Energy-Efficient Broadcast Protocol in Ad Hoc Networks.

Abstract : We investigate minimum energy broadcasting problem where mobile nodes have the capability to adjust their transmission range. Two formulas are generally used when considering this problem. The first, E = r^alpha, depends only on the transmitting range r of a node, while the second, E = r^alpha + c, considers some constant costs independent of the range, like signal processing. The latter seems to be more realistic and is widely used in literature. In this paper, we show that with this second energy consumption model, it is not always optimal to minimize the transmission range. Furthermore, we demonstrate that there exists an optimal radius, computed with an hexagonal tiling of the network area, that minimizes the power consumption. We propose also a localized broadcast algorithm which takes this optimal radius into account. This protocol is shown to be efficient in our comparison with other protocols like LBOP or BIP.
