Energy-efficient operation is one of the prominent challenges for successful deployment of Wireless Sensor Networks (WSNs) along with maintaining certain quality of service (QoS) requirements. In this paper, we tackle the energy-efficient operation of WSN nodes implementation based on the Contiki real-time operating system (RTOS). We review the effect of applying spatial configuration for the radio...
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...
The Routing Protocol for Low power and Lossy Networks (RPL) has recently been considered as the standard routing protocol for wireless sensor networks (WSN). RPL builds routes between nodes based on specific metrics that reflect arbitrary optimization objectives through the RPL Objective Functions (OFs). In this paper, we propose a Context-Aware Objective Function (CAOF) that takes into account the...
Wireless sensor networks (WSN) face several challenges in field deployments due to strict limitations in nodes hardware capabilities and battery capacities. In addition, several environmental factors should be considered while designing or testing a WSN. Energy-efficient operation is one of the prominent challenges for successful deployment of WSN's. In this paper, we consider energy-efficient operation...
