  • Energy-efficient routing for delay-constrained data traffic in linear wireless sensor networks

    Creator:
    Alesaimi, Hani
    Abstract:
    Linear wireless sensor networks (LWSN) are special class of wireless sensor networks where sensor nodes are deployed in a straight line. Monitoring industrial pipelines, railroads, tunnels, power lines, and borders are applications of LWSNs. Wireless sensors are tiny devices with limited energy resources; therefore, efficient energy routing in LWSNs is...

  • Ultra-low power receivers for wireless sensor networks

    Creator:
    Ayers, James S.
    Abstract:
    In wireless sensor network applications, low-power operation of the wireless receiver is critical. To address this need an ultra-low power Binary Frequency Shift Keying (BFSK) receiver using the super-regenerative architecture is developed. A prototype receiver is built and tested for operation in the 900 MHz ISM band. Lab measurements show...

  • Cross-layer aware routing approach for lifetime maximization in wireless sensor networks with multiple sinks

    Creator:
    Hamid, Arwa Zakaria
    Abstract:
    In wireless sensor networks (WSNs) nodes are battery powered. Therefore, the available energy resources of sensor nodes should be managed efficiently in order to increase the network lifetime. As a result, researchers have proposed routing schemes in order to maximize network lifetime. Even though these schemes increase the network lifetime,...
