Abstract

—The paper proposes a new approach to minimize the
number of relays while maximizing the lifetime of underwater
acoustic sensor networks (UASNs). This involves formulating
the relay node placement (RNP) problem as a multi-objective
optimization problem and employing the multi-objective lexicographic method (MOLM) to solve it. To achieve the optimal
solution, the MOLM consists of two steps. First, the problem
of lifetime maximization is tackled to find RNP solutions. This
transforms the RNP into a non-convex optimization problem
which is then converted into a convex programming equivalent.
The proposed method has the same computational complexity
as previous relay-node adjustment (RA) and difference convex
algorithm (DCA) methods. The second step introduces a novel
relay node selection to reach the optimal number of relays.
Simulation results demonstrate that it has superior network
lifetime and efficiency compared to RA and DCA.
