Abstract This report suggests a replacement of the existing Ad-hoc On Demand Distance Vector routing protocol on the SunSPOT (v. 4 Blue release) with an improved protocol, suitable for a dynamic wireless sensor network. One of the characteristic features in the improved protocol is the possibility for multipathing. This enables a message to be sent over more than one route to a sink. Furthermore, this feature will eliminate the necessity for acknowledgements in a network, which will reduce the traffic in the network tremendously. Also noticable, is the fact that a single node in the network has no longer knowledge of the rest of the network, but only of its own neighbours. This protocol is especially well suited for the purpose described in this project, namely sending data from multiple sources to a single sink. Besides the protocol, an intelligent application has been developed for each SunSPOT, making it capable of compressing data when necessary. Additionally, the data can be sent as serialized objects, which makes the handling of data much easier. An initial consideration upon a service oriented architecture approach has been made, and some services have been developed. A GUI has been developed to make the user able to monitor and control the network and the received data. It is also possible to analyse the received data. The usability of the protocol and the application has been thoroughly tested on the SunSPOTs, both with and without the use of GUI. A future use of this application could be for monitoring animals and their behaviour, since this would be a dynamic network where a sink might not always be accessible and data may have to be compressed or routed in an intelligent way.
