network coding has been confirmed as a potential technology to improve performance of wireless mesh networks (WMNs) and a few network coding aware routings have been proposed. However, these mechanisms detect coding opportunities through local traffic pattern checking, which hardly obtains optimal routes. This paper proposes a Genetic algorithm based Coding Aware Routing (GCAR) for wireless mesh networks, which employs genetic algorithm to optimize routes and coding opportunities. In addition, the key ingredients in GCAR, e.g., chromosome representation, genetic operation of crossover and mutation, fitness function considering coding opportunity and interference, are carefully designed. Through simulations on a randomly generated wireless mesh network, GCAR is shown to find optimal routes within a short time, and achieve more improvements than the previously proposed methods on route setup time, throughput and load balancing.

In wireless sensornetworks (WSNs) where the nodes operate on batteries, for which replacement and recharging is almost impossible. So it is critical to prolon g the network lifetime by minimizing the total energy consumption, while satisfying given throughput requirements. With this objective in mind, an automatic retransmission request (ARQ) protocol for exploiting cooperative communication is introduced and a generalized model is proposed for analyzing the throughput and energy efficiency of the scheme. The numerical results reveal that the throughput and energy efficiency of the scheme is much better than that of the traditional ARQ scheme.
Because sensor nodes are typically resource-constrained, the key challenge in Wireless sensornetworks (WSNs) design is the energy-efficiency and how to deal with the trade-off between it and the QoS parameters. Data ...
