Purpose and goal

The following main objectives have been fulfilled- (i) Identification of in-vehicle switch applications that can be hosted on a wireless link (ii) Design and prototype of five promising wireless switch applications powered both by batteries and energy harvesting (iii) Design and development of an in-vehicle wireless sensor network platform to host the wireless devices

Expected results and effects

The following main results have been concluded (i) There are a number of commercially exploitable number of non-timing and safety critical switch applications with a transmission pattern that of a low enough frequency that they can be hosted on a wireless link (ii) For lifetimes of max.15 years specified for commercial vehicle components, batteries are more cost competitive than energy harvesters (iii) Using one 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

Planned approach and implementation

Technology developed in the project falls under two main categories (i) Node development i.e. HW/SW/mechanical development for wireless switch 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 switch applications that are commercially feasible has been developed

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
