Important results from the project
The following main objectives have been fulfilled- (i) Identification of in-vehicle sensor applications that can be hosted on a wireless link (ii) Design and prototype of four promising wireless sensor applications (iii) Design and development of an in-vehicle wireless sensor network platform to host the wireless devices
Expected long term effects
The following main results have been concluded (i) There are an exploitable number of non-timing and safety critical sensor applications with a transmission pattern that of a low enough frequency that they can be hosted on a wireless link (ii) Observed statistical properties of the RF link are such that packet reception rates of more than 90% is possible all over the chassis of a heavy duty vehicle (iii) Using a dedicated gateway for the tractor and one for the trailer, provides a broad enough platform to cover in-vehicle applications under reasonable levels of ambient interference.
Approach and implementation
Technology developed in the project falls under three main categories (i) Node development i.e. HW/SW/mechanical development for wireless sensor nodes and gateway nodes (ii) Network design and development which comprised of planning of deployment locations, evaluating link quality and synthesis of the in-vehicle network (iii) Protocols for network management and operation In addition, guidelines to help choosing wireless sensor applications that are commercially feasible has been developed
