A new computing and communication paradigm for next generation wireless services: low power, secure wireless sensor networks

Wireless sensor networks have emerged as an invaluable tool to bridge the gap between computing infrastructure and the physical world. While sensor networks promise to enable new next-generation wireless services, several daunting challenges remain to be overcome before their potential is realized. Using a ubiquitous healthcare application as an example, this paper discusses several such key challenges and describes research approaches to address them.
