MESSAGE PROJECT AIR POLLUTION SENSOR IEEE 802.11/16 ACCESS POINT SENSOR Wired Internet London Bus Ad-Hoc Networks for Pollution Monitoring Vehicular Ad Hoc Networks (VANETs) Self configuring networks Wireless links Rapid node mobility Subjectivity to frequent fragmentation DATA PROCESSING SITE

Area of Interest (I) TRANSPORT LAYER NETWORK LAYER DATA LINK LAYER PHYSICAL LAYER DATA LINK LAYER NETWORK LAYER TRANSPORT LAYER

Area of Interest ( II ) Some initial ideas Current work integration of knowledge of bus routes to the protocols introduction of special nodes with increased resources and responsibility Current work Delay tolerant networks Possible future directions Crosslayer design Architecture issues

Issues for Investigation Reliable protocols for data transfer Routing for disconnected bus ad-hoc network Optimal locations of road-side access points Cross-layer protocol and system optimisation
