An Adaptive Link Layer for Range Diversity in Multi-Radio Mobile Sensor Networks
Source: University of Massachusetts
An important challenge in mobile sensor networks is to enable energy-efficient communication over a diversity of distances while being robust to wireless effects caused by node mobility. This paper argues that the pairing of two complementary radios with heterogeneous range characteristics enables greater range diversity at lower energy cost than a single radio. The paper makes three contributions towards the design of such multi-radio mobile sensor systems.
