tailieunhanh - A review of dynamic packet reservation multiple access protocol on speech transmission wireless adhoc networks

This paper shows that PRMA is a suitable protocol for the transmission of speech, as it increases the channel capacity by allowing more than one terminal to share a channel. This is done by multiplexing speech terminals in a TDMA fashion while keeping the implementation easier. | ISSN:2249-5789 Nutakki Praveena et al , International Journal of Computer Science & Communication Networks,Vol 3(4),207-213 A REVIEW OF DYNAMIC PACKET RESERVATION MULTIPLE ACCESS PROTOCOL ON SPEECH TRANSMISSION WIRELESS ADHOC NETWORKS NUTAKKI PRAVEENA1, DR.

Abstract This Cellular mobile radio telephony is a new and attractive area of current interest. This paper provides a general idea of the cellular system with particular emphasis on the PRMA protocol for digital speech transmission. This paper shows that PRMA is a suitable protocol for the transmission of speech, as it increases the channel capacity by allowing more than one terminal to share a channel. This is done by multiplexing speech terminals in a TDMA fashion while keeping the implementation easier. This protocol is also suitable for integrated services and further study is in progress for the integration of voice and data with some priority of access mechanism for voice traffic. Keywords: Medium Access Control, PRMA, DPRMA, CPRMA, Slotted Aloha, TDMA. 1. Introduction Wireless communications is, by any measure, the fastest growing segment of the communications industry. As such, it has captured the attention of the media and the imagination of public. Cellular systems have experienced exponential growth over the last decade and there is currently around two billion user worldwide. The current cellular systems, however, are incapable of efficiently and effectively supporting the introduction of multiple traffic types. The cellular systems .
