Communication-based design represents a formal method approach to of system-on-a-chip design that considers communication between components as important as the computations they perform. “Our network-on-chip&rdqo ; approach partitions the communication into layers to maximize reuse and provide a programmer with an abstraction of the underlying(More)
One of the most compelling challenges of the next decade is the " last-meter " problem, extending the expanding data network into end-user data-collection and monitoring devices. PicoRadio supports the assembly of an ad hoc wireless network of self-contained mesoscale, low-cost, low-energy sensor and monitor nodes. While technology advances have made it(More)
A low power wireless intercom system is designed and implemented. Two fully-operational ASICs, integrating custom and commercial IP, implement the entire digital portion of the protocol stack. Combined, the chips consume 13 mW on average when three nodes are connected to the network. A high-level design methodology was used to define the protocol stack and(More)
Localization (a.k.a. locationing) is a central concern for ubiquitous self-configuring sensor networks. In this paper the implementation of a distributed, least-squares-based localization algorithm is presented. Low power and energy dissipation are key requirements for sensor networks. As part of the sensor network, the localization system must also conform(More)
