A Token Forwarding K-Mutual Exclusion Algorithm for Wireless Ad Hoc Networks

A fault-tolerant token based distributed k-mutual exclusion algorithm which adjusts to node mobility is presented. The algorithm requires nodes to communicate with only their current neighbors, making it well-suited to the ad hoc environment. A \token forwarding" modi cation to the basic algorithm is shown to lower the time each node waits to enter the CS by circulating unused tokens among participating processors. Further heuristic modi cations are shown to improve the message complexity of the algorithm.
