Modern software-defined radios are large, expensive, and power-hungry devices and this, we argue, hampers their more widespread deployment and use, particularly in low-power, size-constrained application settings like mobile phones and sensor networks. To rectify this problem, we propose to put the software-defined radio on a diet by redesigning it around just two core chips -an integrated RF transceiver and a Flash-based, mixed-signal FPGA. Modern transceivers integrate almost all RF front-end functions while emerging FPGAs integrate nearly all of required signal conditioning and processing functions. And, unlike conventional FPGAs, Flash-based FPGAs offer sleep mode power draws measured in the microamps and startup times measured in the microseconds, both of which are critical for low-power operation. If our platform architecture vision is realized, it will be possible to hold a software-defined radio in the palm of one's hand, build it for $100, and power it for days using the energy in a typical mobile phone battery. This will make software radios deployable in high densities and broadly accessible for research and education.

“…Once, we apply such techniques, the (common) back-off mechanism of DecTDMA will prevent starvation. The literature considers receiver-side collision detection [12,13], which requires hardware support for signal processing as well as receivers to notify senders about the success or failure of transmissions. In this paper, we assume hardware that does not support collision detection (on the sending side or on the receiving side).…”

In wireless sensor networks (WSNs), different motes may transmit packets concurrently, i.e., having overlapping transmission periods. As a result of this contention, there are no packet reception guarantees and significant bandwidth can be lost. This contention can have a strong impact on the performance together with other kinds of interference sources, e.g., ambient noise. As a result, WSN's connectivity tends to have a very dynamic nature. In this paper, we devise DecTDMA (Decentralized-TDMA), a fully decentralized medium access controller (MAC) that significantly reduces contention. It is based on a self-stabilizing algorithm for time division multiple access (TDMA). This self-stabilizing TDMA algorithm uses no external assistance or external references, such as wireless access points (WAPs) and globally-synchronized clocks. We present the design and implementation of DecTDMA and report encouraging results: our Cooja simulations and Indriya testbed experiments show stable connectivity and high medium utilization in both single and multi-hop networks. Since DecTDMA has favorable characteristics with respect to connection stability, we show that common link quality estimation (LQE) techniques further improve the operation of DecTDMA in the dynamic environment of low-power wireless networks.

Low-power wireless networks must leverage radio duty cycling to reduce energy consumption, but duty cycling drastically increases the risk of radio collisions, resulting in power-expensive retransmissions or data loss. We present Strawman, a contention resolution mechanism designed for low-power duty-cycled networks that experience traffic bursts. Strawman efficiently resolves network contention, mitigates the hidden terminal problem, and has zero overhead unless activated to resolve data collisions. Our testbed experiments show that Strawman instantaneously provides increased network capacity when needed, allocates the available bandwidth evenly among contenders, and increases energy efficiency in multihop collection networks compared to the traditionally used random backoff.
