AReIT: Adaptive Reliable Information Transport Protocol for Wireless Sensor Networks

The reliable delivery of services in service oriented architectures often entails the underlying basis of having well structured system and communication network models. With the rapid proliferation of ad-hoc mode of communication, such as Wireless Sensor Networks (WSNs), the reliable delivery of services increasingly encounters new communication and also network perturbation challenges. Empirically the core of service delivery in WSN is information transport from the sensor nodes to the service via a sink node. In this work we classify the different services provided by the WSNs, and provide a reliable information transport protocol (AReIT) for enhanced service delivery. AReIT exploits the spatial and temporal redundancies inside the WSN to provide efficient adaptation for changing service requirement and evolving network conditions. Simulation results show that AReIT provides tunable reliability allowing to save expensive retransmissions while maintaining the reliability level desired by the service.
