This paper presents the design and implementation of a wireless sensor and actuator network (WSAN) system for calling home robots in indoor environments. The proposed system consists of a network of wireless pyroelectric infrared (PIR) sensor nodes and a mobile actuator node. The PIR sensor nodes are deployed on the ceiling of a room to form a grid topology. The location of a person within the detection...
Robotic routers (mobile robots with wireless communication capabilities) can create an adaptive wireless network and provide communication services for mobile users on-demand. Robotic routers are especially appealing for applications in which there is a single mobile user whose connectivity to a base station must be maintained in an environment that is large compared to the wireless range. In this...
Optimizing energy consumption for extending the lifetime in wireless sensor networks is of dominant importance. Groups of autonomous robots and unmanned aerial vehicles (UAVs) acting as mobile data collectors are utilized to minimize the energy expenditure of the sensor nodes by approaching the sensors and collecting their buffers via single hop communication, rather than using multihop routing to...
