Flexible Mobile Wireless Sensor Networks based on Quality of Observation and Communication
Hiroaki Higaki · Parallel and distributed computing and systems · 2011
In wireless sensor networks where sensor data achieved by sensor nodes are transmitted to a sink node by using wireless multihop transmissions, there are two different types of approaches: high-density approach in which sensor nodes are usually stationary and whole observation area is covered by their sensing ranges and low-density approach in which sensor nodes moves according to the mobility of objectsand sensor data is transmitted along a stable or sporadic wireless multihop transmission route.
