This paper presents a time division multiple access MAC protocol that is specifically designed for applications requiring periodic sensing of the sensor field. Numerical analysis is conducted to investigate the optimum transmission scheduling based on the signal to interference-noise-ratio (SINR) for ground level propagation model applied on wireless chain topology. The optimised transmission schedule...
This paper investigates the use of a wireless sensor network (WSN) for communicating between road-based nodes. These nodes are situated at ground level and two-way wireless communication is required between the nodes and from the nodes to a roadside control unit. Measurements have been carried out to examine the propagation close to the ground to determine the maximum distance between road-based nodes...
