To achieve efficient broadcasting with low interference and low energy consumption, each node optimizes its transmission power. In a tree-based topology, the message of node u can be overheard by nodes which are in the region of transmission radius of node u but not in a logical neighborhood of u. Therefore, some protocols have been proposed to reduce energy consumption by using overhearing. Since...
The topology of a wireless network can have a significant impact on the connectivity, fault tolerance and longevity of a network. Power optimised topology control algorithms including a relative neighbourhood graph (RNG) and a minimum spanning tree (MST) reduce the links in a network topology, while keeping a topology connected. Link redundancy may be critical to cope with faults such as node failures...
