a group of terminals that are unable to synchronize their transmissions or utilize receiver-
feedback to adjust their transmission phases. The authors show that collaborative …

Avoiding collisions is one of the key roles of mediaaccess (MAC) protocols. Since MACAW
and 802.11, carrier sense and exchange of request-to-send (RTS) and clearto-send (CTS) …

This chapter examines various important low duty cycle MAC protocols and the two most
important MAC protocols designed specifically for cooperative Multiple-Input Multiple-Output …

MAC protocols for multi-hop WSNs have to address the challenge of coordinating duty-
cycling transmitters with duty-cycling receivers. All the suggested protocols can be classified …

This paper deals with a novel MAC layer protocol, namely, directive synchronous
transmission asynchronous reception (D-STAR) able to space-time synchronize a wireless …

Wireless Sensor Networks (WSNs) are composed of spatially distributed autonomous
sensor devices, named motes. These motes have their own power supply, processing unit …

This paper deals with a novel MAC layer protocol, namely Directive synchronous
transmission asynchronous reception (D-STAR), which is able to logically synchronize a …

Low-power wireless communication is a central building block of cyber-physical systems
and the Internet of Things. Conventional low-power wireless protocols make avoiding packet …

A node equipped with a multi-beam antenna can achieve a throughput of up to m times as
compared to a single-beam antenna, by simultaneously communicating on its m non …

En los últimos años las redes de sensores sin hilos se han convertido en una interesante
área de investigación debido principalmente a los retos que presenta su diseño pero …
