—The Internet of Things (IoT) offers the promise of integrating the digital world of the Internet with the physical world in which we live. But realizing this promise necessitates a systematic approach to integrating the sensors, actuators, and information on which they operate into the Internet we know today. This paper reports the design and development(More)
Many heap-oriented languages such as Lisp and Id depend on run-time garbage collection to reclaim storage. Garbage collection can be a signiicant run-time expense, especially for functional languages that tend to allocate structures often. Compiler-directed storage reclamation reduces the run-time overhead of garbage collection by h a ving the compiler(More)
—Commercial cellular networks emerged from the wired public switched telephone networks (PSTN) in an evolutionary manner. Market pressures fueled upgrades in bandwidth and functionality. Four decades later, these networks maintain historical artifacts from PSTN networks, and the artifacts work against the fundamental needs of today's wireless systems.(More)
Mobile devices have evolved to become computing platforms more similar to desktops and workstations than the cell phones and handsets of yesteryear. Unfortunately, today's mobile infrastructures are mirrors of the wired past. Devices, apps, and networks impact one another, but a systematic approach for allowing them to cooperate is currently missing. We(More)
We apply an evolutionary strategies (ES) algorithm to the problem of designing modulation schemes used in wireless communication systems. The ES is used to optimize the digital symbol to analog signal mapping, called a constellation. Typical human-designed constellations are compared to the constellations produced by our algorithms in a simulated radio(More)
—Connected embedded systems in the realm of smart infrastructures comprise ubiquitous end-point devices supported by a communication infrastructure. Device, energy supply and network failures are a reality and provisioned communications could fail. Self-organization is a process where network devices cooperate with each other to restore network connectivity(More)
—The Internet of Things (IoT) aims to integrate the digital world of the Internet with our encompassing physical world. However, existing IoT systems do not provide considerate services, meaning that sensors dynamically " collaborate " to provide context-aware federated sensor data, tuned to human needs. This paper reports our ongoing work developing a(More)
—The impact that widespread disasters have on communications systems has evolved over time – fueled by advancements in technology and cemented by societal adoption. As the use of IP-based communications systems, both wired and wireless, has become ubiquitous, we as a society have become dangerously dependent. We vest our banking and healthcare records in(More)
