In this book, the adaptive slotted ALOHA based p-persistent CSMA MAC protocol for the data link layer and the enhanced energy conservation based on residual energy and distance (EECRED) routing protocol for the network layer were proposed to minimize the probability of collisions by selecting the correct nodes to operate as routers, in addition to using multi-hop techniques. The two proposals were combined by designing a cross-layer protocol to address the energy consumption of more than one layer at the same time. Furthermore, the influence of static distribution and random distribution has...

Wireless sensor network (WSNs) is one of the most important and fast-growing wireless networks. However, it faces real challenges with energy conservation. There are different reasons to consume energy such as idle listening, overhearing, control packet overhead, and collisions. The hidden node problem is the main cause for network collisions and heavily degrade the network performance overall. In addition, throughput degradation and delay time to successfully send data were increased. MAC layer is mainly responsible for accessing transmission channels so that with a good channel access...

Drahtlose Sensornetzwerke (WSNs) sind eines der wichtigsten und am schnellsten wachsenden drahtlosen Netzwerke. Die Energieeinsparung stellt sie jedoch vor große Herausforderungen. Es gibt verschiedene Gründe für den Energieverbrauch, wie z. B. untätiges Zuhören, Überhören, Overhead für Kontrollpakete und Kollisionen. Das Problem der versteckten Knoten ist die Hauptursache für Netzwerkkollisionen und beeinträchtigt die Netzwerkleistung insgesamt erheblich. Darüber hinaus wurden der Durchsatz verringert und die Verzögerungszeit für das erfolgreiche Senden von Daten erhöht. Die...
