Essential to adaptive devices is the ability to reconfigure Medium Access Control (MAC) protocols to environment conditions and application requirements. We propose MadMAC, a platform for building reconfigurable MAC protocols on commodity 802.11x hardware. Programming on top of MadWiFi, MadMAC transmits packets at configurable time and frame format. In this paper, we build a TDMA-based MAC prot...

The Universal Mobile Telecommunications System (UMTS) will provide multimedia services to users in whatever environment via uniform service access procedures. Efficient Medium Access Control (MAC) protocols are needed to guarantee high capacity. This paper deals with Packet Reservation Multiple Access (PRMA), an efficient MAC protocol that has been widely studied in terrestrial microcellular sy...

In this paper the design of a multiservice MAC (Medium Access Control) protocol, as a candidate for the uplink communication channel for LEO constellations is proposed. The proposed scheme is just the combination of conventional PRMA protocol and CDMA techniques, which seems to be a very promising access method for the case of mixed voice/data traffic. A transmit permission technique based on D...

Ultimate aim of authors is to implement a high energy efficient data transmission protocol for Mobile Adhoc Networks (MANET) which prolongs the life time of network in a significant way. MANET devices mainly depend on a limited battery power supply to maintain the network with low power consumption techniques by utilizing the available protocol algorithms with enhanced transmission coverage ran...

Wireless sensor networks rely on the cooperative effort of the densely deployed sensor nodes to report the detected events. As a result, sensor observations are highly correlated in the space domain. Typically, multiple sensor nodes may report the same event. Consequently, redundant information may be transmitted by the different sensor nodes, leading thus to unnecessary energy wastage. In this...

Many medium access control protocols have been proposed for optical wavelength division multiplexing local area networks with a star topology. These protocols range from those based on the concept of fixed-assignment of communication subchannels, such as TDMA (Time Division Multiple Access); random-access to communication subchannels, such as DTWDMA (Dynamic Time-Wavelength Division Multiple Ac...
