Hardware Level Enhancements
IDEA: Main work areas • Work will concentrate on 3 main work areas: 1. Hardware level enhancements for mobile wireless sensor nodes 2. Network level enhancements and protocol design for self organizing wireless networks 3. Setup of a demonstrator as proof of concept
• Single Board Computer, minimum processing capability, minimum price/node • System runs Windows Embedded, Windows XP or Linux (Voyage: slimmed down Debian)

Adding embedded energy scavenging to the motes
• Circuits for Multimodal (orthogonal) energy scavenging •X-layer optimisations on computing layer (QOS/responsiveness) •X-layer optimisations on protocol level (measure/adapt) •X-layer optimisations on network level (learning/negotiating)
45
Optimizing the MAC layer • Communication unit uses up most of the energy • Should be put to sleep if no communication is needed by MAC • MAC protocol allows node to be able to talk to neighbor when this one is awake • Use one or more channels 47

Why multiple channels? • If there’s a lot of traffic on the 802.11 wireless links, a lot of channels on the 802.15.4 spectrum will be unavailable
Why Multiple Channels? • Multiple channels more bandwidth • Parallel communications without interference
