Abstract
Mobile ad-hoc networks (MANETs) present a complex management scenario due to the wireless medium, lack of defined infrastructure, and movement of nodes. Making a configuration change to all nodes in a wireless MANET is difficult when reliability must be guaranteed. If performed incorrectly there is the potential to permanently cripple the network.; Based on experimental results the protocol is found to successfully execute a mass configuration change using modes with confirmation for 10-node MANETs with link loss rates approaching 20% and mobile topologies.; Protocol performance is tested and validated using emulation for static and dynamic topologies, several message sizes, and a range of link loss rates. Execution rate, total duration, and the number of sent messages are used as analysis metrics measuring success, speed, and efficiency.; MCONF, the protocol developed and detailed here, provides a means to successfully perform a mass configuration change with various modes of operation to account for different operating situations. The root node may unconditionally initiate a change or decide conditionally based on feedback from other nodes. Nodes may also wait for confirmation from one-hop neighbor nodes before passing messages or executing.; Existing configuration protocols focus on setting up initial node addressing or are intended for full configuration updates. Many are designed for wired networks and fail to operate correctly in a wireless environment. Consensus protocols are more suited to this task, solving the difficult problem of having all nodes arrive at a joint decision. However, they involve more overhead than needed for a configuration change dictated by a single node.;
