Abstract

In comparison to randomly deployed WSNs (Wireless Sensor Networks), pre-configured WSNs are superior in network performance for many aspects, including end-to-end delay time, data delivery ratio, and energy consumption. Several topologies concerning with pre-configured WSNs, such as grid, hexagonal, or de Bruijn, were proposed in past studies. The common flaws among them are that, the number of neighbors a node could have is so scarce as to significantly affect their fault-tolerance capabilities, and a longer network diameter often introduces a considerable transmission delay. In this paper, we thus propose an efficient and reliable network architecture, named as PyraNet, for pre-configured WSNs. In PyraNet, sensor nodes are first deployed as a pyramidal shape, and then a hypercube address allocation scheme is employed for its routing. Simulation results show that, for large-scale faulty networks, the proposed integrated architecture can achieve about 6%~14% improvement on data delivery ratio, compared to existing architectures. In addition, the energy consumption can also be reduced by 27%~61%, and thus effectively prolongs the network lifetime.
