Executive Summary
• Network Security System using Camera, Radar, and Ground Sensors
• Department of Homeland Security (DHS) Customer
• Stakeholders include:– DHS Contractors– DHS Border Agents
– Cyberdine Systems Development Team– Location Law Enforcement– Local Government Officials
• Base stations (BS) for Computer Networks • Sensor Towers• Sensor Networks joining Area BS and Towers

SBINet Sensor Network Overview
• Ad hoc network (self-organized)• Environment-to-person colaboration communication• Nodes:
– Large Number (100-1000s)– Sensing Capabilities include Radar, Camera, Ground– Communication, Processing, Memory Capabilities– Comprehensive Situational Awareness
• Base station - BS– Common Operating Picture (COP) Stations
– Command Controller (C2)– Mobile and Stationary COPs

SBINet Sensor Network Applications
Possible tasks:• Data Gathering:
– seismic– acoustic– intelligence
• Monitoring:– Climate– Equipment– Movement– Security Areas
Possible users:- Authorities
-Disaster prevention- Security monitoring- Contraband Smuggling- Law enforcement
- Scientific community • Create or validate models
- Private (home automation)- Vacation Monitoring - Remote Controlling

SBINet Network Design Issues
• Power efficiency– Node life-time– Network life-time
• Localization– Range based (Time Of Flight, RSSI etc.)– Range free (based on anchors with known positions and hop
count)– GPS, JTRS, and P25 Radios integrated with C2 Controllers– Tower Based Radar and Camera sensorss
• Security– Secure Positioning, User Authentication, PKI Key Encroption– Data Validation with Role Based Priviledges
• Packaging– Strong environmental constraints depending on the
application
• Data Processing

Risk Mitigations
• Financial, Operational, and Schedule
• Prototype System using Sensor Simulations– Reduces Protype Sensor Hardware Costs– Validates System Interfaces for Next
Spiral– Reduces Development Schedule Time– Re-use prior system service orientated
software (SOA) services• Use Engineering Change Proposal (ECP) process to
track requirement changes
8
Contract Risk Reduction
– Cost Plus Award Fee (CPAF) contract • a base amount fixed at inception of the contract• an award amount that maybe earned in whole or in part during
performance.
– The DHS decided on a CPAF contract to provide motivation for excellence in the areas including quality, timeliness, technical ingenuity, and cost effective management
– Use virtual teams at different contractor location• System Engineering at Huntsville, AL• Software development at Mesa, AZ• System Testing at Huntington Beach CA

A platform for area monitoring sensors
• Made by Crossbow
Technology Inc
• Designed for sensor
networks
• Atmel ATMega128 processor
• Chipcon CC1000 radio
• Runs TinyOS from its Flash
Memory
• 51-pin connector to interface itself
• Add-on sensor boards provide
sensing for Temperature, Humidity,
etc.5

The Operating System: Linux
• Open source real-time OS with outstanding securiity features
• Libraries includes network protocols & distributed services
• Support for Service Orientated Architecture (SOA)
• Powerful and flexible OS with large community support
