Many sensor network design problems are characterized by the need to optimize multiple objectives. However, existing techniques in sensor network design generally optimize only one objective while treating the others as constraints or convert the multi-objective optimization problem into a single objective optimization problem using weights associated with different objectives. The weighted sum approach...
This paper discusses the use of continuous-time sigma-delta modulators for ADCs in wireless biomedical sensing applications. The advantages of the proposed continuous-time sigma-delta modulators include the fact that it eliminates the need for an anti-aliasing filter in front of the ADC because of its intrinsic anti-alias filtering property. Additionally, the use of weak inversion and a low flicker...
We consider the use of a novel load balancing-aware routing algorithm for multipath wireless sensor networks. Focusing on solutions that minimize end-to-end delay, we optimize resource usage in mobile nodes. An analytical model is provided for flow-level multipath routing design; we then proceed to simplify the model for more practicality while retaining much of the original functionality. The practical...
We present the feasibility and optimization of wireless powering of sensors embedded in concrete that relies on a plane wave propagation model. Transmission loss and propagation loss of RF wave penetrating into concrete at different humidity conditions are calculated for various frequencies, thus an optimum frequency range is identified for the wireless power transmission. The optimized rectenna is...
