1.多址接入协议(multiple access protocol)划分为哪三种类型?其中,哪一种(或几种)是无冲突的协议?哪一种(或几种)是有冲突的协议? 答: 多址接入协议划分为信道划分、随机接入、轮流协议三种类型。 信道划分和轮流协议是无冲突的,随机接入是有冲突的。 2.为什么ARP请求封装在一个广播帧中发送,而ARP响应封装在...
Ultra-wide bandwidth (UWB) is a prospective radio technology for wireless networks. As being approval by FCC, UWB radio has received much attention. In this paper, we propose a new multiple access protocol for time-hopping UWB ad-hoc network. As UWB system is a carrier-less impulse radio ...
For the shared channel in wireless Ad Hoc networks, the MAC access protocol with delayed backoff window scheme is commonly adopted. This paper presents a new multiple protocol based on the Active State of Neighboring Nodes (BASNN) for Mobile Ad Hoc Networks. If a source node has a packet ...
FDMA: frequency division multiple access 信道频谱划分为若干频带(frequency bands) 每个站点分配一个固定的频带,不会冲突但信道利用率可能不高;无传输频带空闲 如图:6站点LAN, 134频带传输数据,256频带空闲。 CDMA: code division multiple access 每个用户分配一个唯一的m bit码片序列(chipping sequence),其中“0”...
Wireless ad-hoc networks have seen much attention in recent years, for the numerous benefits they offer. There are still a number of open research questions regarding these networks, and this paper addresses the question of which duplexing, multiplexing, and multiple access (D/M/MA) techniques ...
Multiple Access Protocols Is a Data link layer(MAC) protocol. Data link layer has two sublayer: LLC(logic link control), MAC(media access control) If there is a dedicated(专用的) link between the sender and the receiver then data link control layer is sufficient,such as Point-to-Point to...
HYMAC: Hybrid TDMA/FDMA Medium Access Control Protocol for Wireless Sensor Networks We describe HyMAC, a new hybrid MAC layer protocol for wireless sensor networks that is, to the best of our knowledge, the first effort to combine the stre... M Salajegheh,H Soroush,A Kalis - IEEE Intern...
At the same time, similar to a reservation based protocol, the token strategy avoids collisions and is able to guarantee efficiently the integrity of the transmitted data. 展开 关键词: access protocols broadband networks code division multiple access delays land mobile radio packet radio networks ...
