A clustering Group Mutual Exclusion algorithm for mobile ad hoc networks

A mobile ad hoc network can be defined as a network that is spontaneously deployed and is independent of any static network. The network consists of mobile nodes with wireless interfaces and has an arbitrary dynamic topology. The networks suffers from frequent link formation and disruption due to the mobility of the nodes. A clustering method is used for obtaining a hierarchical organization for the ad hoc networks. In this paper we present a clustering token based algorithm for Group Mutual Exclusion in ad hoc mobile networks. The proposed algorithm is adapted from the RL algorithm in and utilizes the concept of weight throwing in. The proposed algorithm is sensitive to link forming and link breaking. The algorithm ensures the mutual exclusion, the bounded delay, and the concurrent entering properties.
