Abstract: Previous mutual exclusion (MUTEX for short) protocols for mobile ad hoc networks are based on the token circulation technique. They assume that the network is reliable to avoid starvation. Considering that the MUTEX issue is to share a communication channel, we have designed an average-case-analysis protocol for single-hop networks which is based on the fully distributed construction of a random binary tree. Contrarily to other papers, the stations are not identified and their number (n) is unknown. Assuming that time is slotted, our algorithm runs in approximately n/log 2 slots. The derived k-MUTEX protocol runs in n/log k slots.

Keywords: mutual exclusion; k-mutual exclusion; ad hoc networks; mobile networks; wireless networks; fault tolerant algorithms.
