Same story as wired world multi protocols just no wires!
Need for both a gateway and integration platform

8. Wireless Value Proposition
Installation cost
Resource savings
Implementation time
Ideal for moving and movable assets
Operational Savings
Travel, Labor

9. Wireless Issues & Concerns
Batteries
Replacement labor
Environmental Issues
New battery and power technologies
Loss of Service
We deal with it every day
Must be considered
Self healing networks and smart routing

10. What is ?
IEEE standard for low cost, low speed, low power wireless communication
Targeted at device to device communication
Supports multiple frequencies, including the worldwide unlicensed 2.4 GHz band
Sixteen channels
Shares spectrum with (WiFi) and Bluetooth
250 kbit/s data 2.4 GHz
127 bytes max packet length
Each device has a unique 8 byte identifier (MAC address)

11. Networks
specification defines methods by which devices can form networks
Networks are known as Personal Area Networks (PANs)
Each network has a unique PAN ID
Three type of nodes – coordinator, routers, end device
Network is managed by the “coordinator”
When end devices start up, they broadcast a request to associate with a network
Coordinator will respond to association request and assigns address to device, updates routing tables throughout the network
Multiple network topologies supported, but not specified by standard.
types include star, tree, linear and mesh
Each topology requires a different routing algorithm

12. Star Network Simplest network All traffic routed through coordinator
Limited coverage and quantity since all nodes must be within RF range of the coordinator
Requires smallest code and memory footprint
End devices can sleep to conserve power

13. Tree Network Larger coverage area than star network
Messages between nodes must get routed to first common ancestor
End devices (G & H) can sleep
Moderate code and memory requirements
A self-healing tree can re-route automatically if link to parent is broken
Example: If G loses communication with E, it could become a child of B

14. Linear Network
Specialized version of the tree network with similar code and memory requirements
Large coverage area
Single path between all devices

15. Mesh Network
Each node dynamically determines best path to other nodes, changing its routing as paths fail or degrade
Most complicated routing algorithm, requires largest code and memory footprint
All devices that perform mesh routing must be powered

16. Hotel Case Study Hotel PTAC Unit Control Cost Sensitive Product
Cost Sensitive Industry
Low Tech Install and Maintenance
Potential for Savings
Energy and Operational

Highly Integrated “Single Chip Solution”
Feature rich microcontroller + IEEE compliant transceiver
Networking Stacks
Designed for flexibility, low power operation, co-existence, stability and robustness
For sensor and control networking

23. IPv6 Next generation of Internet Protocol (IP) addressing scheme
Expands address space from 4 bytes to 16 bytes
2128 bits worth of address space
~3.4 x 1038 addresses
Lots of address space = well suited for addressing devices and M2M applications
Every switch, lamp, appliance, etc. in your home can now have its own IP address
Uses different notation for specifying addresses
IPv
IPv :0db8:0000:0000:a526:2962:3960:c0e1

24. What is 6LoWPAN?
6LoWPAN = IPv6 over Low power Wireless Personal Area Networks
Internet standard defined by IETF
RFC4944 – Transmission of IPv6 packets over IEEE
Large open community concerned with evolution of the Internet architecture – network designers, operators, vendors, researchers
Enables wireless devices to interoperate with other IP-enabled devices using standard protocols
An extension of wired IP into the wireless domain…..
Benefits: global addressing / routing – it’s a Standard..
Devices have globally unique addresses

25. 6LoWPAN - Purpose
To extend IP services down to low power, embedded wireless devices – sensors, controls, actuators
Enabling IP and wireless to work together
Small packet sizes, low power consumption, a protocol stack suitable for embedded devices – small footprint, efficient
6LoWPAN defines IPv6 packets over IEEE
Packet fragmentation, header compression, multi-hopping
Compact and efficient implementation for low power wireless
Clusters of wireless nodes connected to the wired infrastructure
Nodes within a cluster talk wirelessly
Nodes on different clusters talk through the wired domain
Benefits from reuse of existing IP infrastructure
Simple integration and deployment

26. Why use 6LoWPAN? Leverages existing standards
IP is the field-proven protocol winner
Generic solution regardless of device or application type
Permits integrating devices without requiring gateway cognizant of the application
A programming tool can communicate directly to a device without special application software and mapping, communications are simply routed through the network!
Works with wired and wireless devices, just like the computer world, just like the telecom world.
A smart 6LoWPAN router can present an IPv4 address. In this case the router will have a configuration table to handle mapping the extended address to IPv4 addresses.

27. Basic 6LoWPAN Network Internet,
Note that the 6lowpan does not need to be cognizant of the device types on the mesh network – it simply converts the packet headers between IPv6 and 6lowpan format.

31. Wired / Wireless Solution
Wireless works well in some environments but isn’t suited for all situations
Use a wired backbone
Extends range of wireless network
Eliminates RF interference in problem areas
Wired backbone acts as a high-quality wireless link
Wired/wireless devices form single network with IP addressing throughout
Similar to deploying both WiFi and wired Ethernet connections
Best of both worlds!
FIXX – need to build stronger case for wired solution – what are we tr
