Abstract
In the current work the effects of hop-by-hop packet loss and retransmissions via ARQ protocols are investigated within a Mobile Ad-hoc NET-work (MANET). Errors occur due to outages and a success probability function is related to each link, which can be controlled by power and rate allocation. We first derive the expression for the network's capacity region. A network utility maximization problem (NUM) with stability constraints is further formulated which decomposes into (a) the input rate control problem and (b) the scheduling problem. The NUM problem can be solved in a fully decentralized manner if (b) is solved distributedly. Use of supermodular game theory suggests a price based algorithm that requires minimum information exchange between interfering nodes and converges to a power allocation which satisfies the necessary optimality conditions of (b). Simulations illustrate that the suggested algorithm brings near optimal results.
