What are “Ubiquitous Wireless Sensor Nets?”
A Network of hundreds, thousands, or millions of micro-scale or nano-scale devices used to instrument some physical space…– Machinery Instrumentation– Habitat Monitoring– Inventory and Asset Tracking– Battlefield– Perimeter Surveillance
Features of Sensor Nets– Power Plant (Generation, Scavenging and Storage) – Detectors (CBRN, Acoustic, SIGINT, EO/IR, etc.)– Computational Layer– At least one communications medium– Camouflage– Efficient software functions primarily concerned with
communications and resource management

What’s the problem with the market?
No Standard for judging/measuring the suitability of a particular solution– Mission Life– Sense Modalities– Intranet and Internet Communications– Efficiencies– Latencies between detection and comms– Security/Encryption– Method of deployment– Form factor– Disposability

Sound Familiar?
In the 1980s, this was the case with Database Software Offerings…– Which was best?– What kinds of tasks were “typical?”– Were Updates, Deletes, Inserts or Queries the activity that
drove acquisition decisions?Transaction Processing Council Benchmarks– Designed to provide standard, typical transactions designed
to assist in evaluating software and system performance– TPC-A (OLTP Update Intensive DB Transactions)– TPC-B (non-OLTP, DB Performance Stress Testing)– TPC-C (OLTP, complex, concurrent DB transactions)– Others

Proposal
Create an “Industry Standard”
portfolio of military and commercial“Missions”
that isolate the problem spaces solvableby UWSNs!

Summary and RecommendationConclusions– 3 Different Missions require 3 different approaches to UWSNs.– Missions for surface, subsurface, space, mountainous terrain, caves
and other possible battlefields are required– Scientists and Engineers always produce better product when they
understand the problem they’re trying to solve!Recommendations to Academia, Industry & Government– Mission profiles should NOT specify the solution
Just the mission objectiveThe Nuances of the battlefieldThe requirements for Situational Awareness/Understanding by warfighters & commanders
– Mission profiles should be modeled (simulated), published, and continuously improved or refined in order to present…
The most realistic set of requirementsThe probability spaces of mission variablesMissions that change dramatically before completionPost mortem mission activities (cleanup)
