A Cross-Layer Strategy for Energy-Efficient Reliable Delivery in Wireless Sensor Networks
Overview This paper investigates the problem of the lifetime maximization in wireless sensor networks under the constraint of end-to-end transmission success probability, by adopting a cross-layer strategy that considers physical layer (i.e., power control), MAC layer (i.e., retransmission control) and network layer (i.e., routing protocol) jointly. The paper decouples the problem into separate sub-problems of each layer and proposes the optimal algorithm as well as an alternative heuristic algorithm with lower complexity for each sub-problem. This paper demonstrates through computer simulations that a trade-off relation exists between the network lifetime maximization and the reliability constraint, and the strategy that is designed by combining the proposed algorithm at each layer can significantly increase the network lifetime.
