title: Creating Zigbee Ad-hoc Network in a dynamic environment
body: <p>We are working on a project to create a V2V ad-hoc network between vehicles. Basically we are deploying Raspberry Pis in vehicles and we are using Xbee modules and Zigbee protocol in order to exchange data between vehicles if they are near from each other. </p>
  
  <p>Our ad-hoc network is completely dynamic and decentralized (We cannot have any static nodes in the network). Our problem is that the topology of the mesh network created by the Zigbee protocol requires a coordinator to be always in the network and the network will fail in case this coordinator failed down. </p>
  
  <p>It seems that using Zigbee protocol requires knowing the topology of the network beforehand.</p>
  
  <p>We do not know whether it is feasible to create our dynamic network using the Zigbee protocol without knowing the topology of the network beforehand and without the requirement of the coordinator. Can we have more than 1 coordinator in the network to overcome this problem? Thanks in advance.</p>
