Hop Reservation Multiple Access (HRMA) for Multichannel Packet Radio Networks
A new multichannel MAC protocol called Hop Reservation Multiple Access (HRMA) for packet-radio networks is introduced, specified and analyzed. HRMA is based on very-slow frequencyhopping spread spectrum (FHSS) and takes advantage of the time slotting necessary for frequency hopping. HRMA allows a pair of communicating nodes to reserve a frequency hop (channel) using a hop reservation and handsh...
متن کاملHop Reservation Multiple Access (HRMA) for Ad-Hoc Networks
A new multichannel MAC protocol called Hop-Reservation Multiple Access (HRMA) for wireless ad-hoc networks (multi-hop packet radio networks) is introduced, specified and analyzed. HRMA is based on simple half-duplex, very-slow frequency-hopping spread spectrum (FHSS) radios and takes advantage of the time synchronization necessary for frequency hopping. HRMA allows a pair of communicating nodes...
متن کاملA Variable Partition Duplex Scheme with Enlarged Reservation Duration on Packet Reservation Multiple Access Protocol ∗
SUMMARY A variable partition duplex scheme on packet reservation multiple access protocol (VPD-PRMA) is analyzed in this paper. We assume a four-state speech model for a conversational pair and successfully obtain performance measures by approximate Markovian analysis. Analytical results show that they quite fit simulation results; and VPD-PRMA can get higher statistical multiplexing gain than ...
متن کاملDRMA with Multiple Slots Reservation and Retransmission Algorithm Using Exponential Backo Scheme
Dynamic reservation multiple access (DRMA) has been proposed to improve the spectrum e ciency of the integrated voice and data services. In that protocol, although the xed reservation overhead is avoidable, a data terminal that transmits a data message with multiple packets has to reserve a slot for each packet transmission. In this paper, to improve the data message delay without degrading the...
متن کاملDistributed Reservation-Based Code Division Multiple Access
The use of spread spectrum signaling, motivated primarily by its antijamming capabilities in military applications, leads naturally to the use of Code Division Multiple Access (CDMA) techniques that permit the successful simultaneous transmission by a number of users over a wideband channel. In this paper we address some of the major issues that are associated with the design of multiple access...
