Experiments with wireless sensor networks have shown that unidirectional communication links are quite common. What is even more, they have also shown that the range of a unidirect...
Abstract. Recent experimental studies have shown that radio links between low-power devices are extremely unreliable. In particular, the instability and unpredictability of low-pow...
Motivated by the needs of precise forest inventory and realtime surveillance for ecosystem management, in this paper we present GreenOrbs [1], a wireless sensor network system and...
