Exploiting Opportunistic Overhearing to Improve Performance of Mutual Exclusion in Wireless Ad Hoc Networks

Free registration required

Executive Summary

The authors design two mutual exclusion algorithms for wireless networks. Their mutual exclusion algorithms are distributed token based algorithms which exploit the opportunistic message overhearing in wireless networks. One of the algorithms is based on overhearing of token transmission. In the other algorithm, overhearing of both token and request messages is exploited. The design goal is to decrease the number of transmitted messages and delay per critical section entry using the information obtained from overheard messages.
