In addition to the special field topology, a parking garage wireless sensor network restricts power consumption and data transmission time in terms of hardware equipment and service management. Without the consideration of node load or packet collision in the route of data transmission from a sensor to the sink node, the node will not only exhaust the energy but also may not transmit the data to the...
This paper presents the design of a duty-cycling MAC, called PRI-MAC (Pipelined-forwarding, Routing-integrated, and effectively-Identifying MAC), for large-scale wireless sensor networks. PRI-MAC divides the whole network into grades around the sink node. The higher grade a node is in, logically the further away it is from the sink which is in the lowest grade. Staggered sleep-wakeup schedules are...
As chip multiprocessors keep increasing the number of cores on the chip, the network-on-chip (NoC) technology is becoming essential for interconnecting the cores. While NoCs result in noticeable performance boost over conventional bus systems, they consume a non-negligible fraction of the system power. One promising solution is to dynamically adjust the working frequencies/voltages of the switches...
Multi-hop relaying helps to improve the connectivity in wireless networks at the price of additional signaling overhead. In this paper, an ultra-low power wake-up radio is proposed to minimize signaling overhead and to build up energy-aware relaying route for low power applications. Protocol details are explained and energy consumption model is analyzed. The proposed scheme is compared with main radio...
In this paper, we proposed bandwidth based power-aware routing protocol with signal strength detection instead of using GPS. In our proposed routing protocol, we used the variation of received signal strength to predict transmission bandwidth and lifetime of a link. Accordingly, the possible data transmission amount and remaining power after data transmission can be predicted. With the prediction...
In this paper, we propose a power-aware routing protocol with low route requests that finds a path with high path bandwidth. To have low routing requests, mobile nodes help to broadcast the routing request only when they first receive the routing requests. In addition, based on the receipt of the routing requests from the neighboring nodes, a mobile node records the location information of its one-hop...
An intermittent transmission control in the MAC layer protocol is very important for managing the energy consumption of wireless sensor networks. This research focuses on an intermittent receiver-driven data transmission (IRDT) protocol in which communication starts when multiple receiver nodes transmit their own IDs intermittently and a sender node receives them. This method aims at prolonging network...
3D contactless technology based on capacitive coupling represents a promising solution for high-speed and low power signaling in vertically integrated chips. AC coupled interconnects do not suffer from mechanical stress, and the parasitic load is much reduced when compared to standard DC solutions, such as wire bonding and micro bumps. Communication system based on wireless interconnection scheme...
