The dissemination of information in wireless networks is a fundamental aspect in several network processes, such as routing, monitoring and management. Nowadays, most of the techniques for dissemination of management information adopt controlled flooding approaches, which usually impairs the network performance. In this sense, the optimization of the dissemination of management information for dense wireless scenarios remains a relevant research challenge. In this paper, it is presented and analyzed the performance of the Neighbors Eyesight Direction (NED) dissemination against to OSPF, uncontrolled flooding and Gossip approaches in wired and large network scenarios. NED is able to work on wired and dense wireless scenarios, showing to be more efficient than the baseline approaches. With lower dissemination cost and lesser recursive cycles, NED proved to be scalable to disseminate management information for scenarios with a large number of devices.

This paper proposes mobility-enabled and loop-free extensions to the Spanning Tree Protocol (STP) for wireless ad hoc environments, taking into account requirements such as loop avoidance, root selection, ability to deal with interference, path loss or multipath fading, all without requiring to modify the existing protocol stack. Our approach is compliant with IEEE 802.11 networks and considers that mobile nodes constantly join and leave the range of each other due to their unpredicted movements, often changing the network topology. This implies that coherent information must be forwarded between nodes in order to keep their distributed knowledge synchronized, to allow the spanning tree topology maintenance and avoid or remove undesirable loops in multi-hop paths. The results obtained through simulation show that WSTP ensures a lower distance between the nodes and the root when compared to an approach that performs associations based on the first contact, and therefore, it provides a lower resource consumption and lower delay in the communications.
