ABSTRACT
In this paper, we investigate the problem of joint power allocation and routing optimization for the minimization of end-to-end outage probability in Decode-and-Forward (DF) multi-hop wireless networks. To solve the problem, we developed a new joint power allocation and routing strategy. First, a closed-form expression for power allocation is derived, and from this solution, routing metric is obtained, which solves the routing problem. We also present distributed implementation of joint power allocation and routing strategy. Simulation results show that the proposed scheme significantly controls end-to-end outage probability.
