摘要:

结合几种基本的MAC接入协议,对Ad Hoc网络中存在的封闭问题进行了分析,同时指出了不同协议中封闭问题的差异。提出了一种改进型的PCMA协议——DBT-PCMA协议,并重点剖析了PCMA协议和DBT-PCMA协议是如何解决封闭问题的。经分析表明,该改进型的新协议能更好的降低封闭问题的发生机率,并提高系统的吞吐量。

关键词: Ad Hoc, 封闭, 吞吐量

Abstract:

The blocking problem in Media Access Control (MAC) protocols of Ad Hoc networks is analyzed.an improved PCMA protocol,DBT-PCMA,is proposed after an analysis of the diversity of blocking problems in different protocols.The solutions to the blocking problem in PCMA protocol and DBT-PCMA protocol are discussed.The analysis shows that the proposed protocol can reduce the odds of the blocking problem efficiently,and improve the system throughput.

Key words: Ad Hoc;blocking;throughput
