Analysis and Research on Hidden Terminal and Exposed Terminal Problems in Ad Hoc Networks

Lan Li

Abstract

Hidden terminal problems and exposed terminal problems are the inherent problems in MAC layer in Ad Hoc networks, and becomes the vital factor of limiting the performance of the network. Describes the problems of hidden terminal and exposed terminal, analyzes the ways of solving this problems, contrast several protocols, which based on IEEE 802.11 protocol, taking into account of the nodes' states and packets' sizes, making the hidden terminal and exposed terminal join in the concurrent communication, proposes some improved measures.
