Abstract
In this paper, we present the Context-Aware Opportunistic Resource-Based Routing Protocol (CORB) for intermittently-connected stationary wireless sensor networks. This protocol targets domains such as ambiance control in smart buildings. Unlike existing context-aware routing approaches which consider node mobility as the main source of disconnection, CORB only considers the nodes' limited resources and context as the reasons for intermittent connection. Performance evaluation results show that the proposed CORB protocol does not only outperform existing context-aware routing protocols but also significantly outperforms the IP Ripple Routing Protocol (RPL) designed specifically for low power and lossy networks. In grid topologies (sink-centered topologies), the delivery ratio of CORB under heavy loads is up to 404% and 296% (143% and 46.6%) of the original context-aware routing protocol and IPv6 RPL, respectively.
