Wireless network topologies have developed in a considerably different manner than the original vision of the ad-hoc network. Rather than a number of nodes with similar capabilities moving about in randomly in an open field, today's wireless topologies are both hierarchical and heterogeneous. They consist of nodes with very different capabilities and contain both infrastructured and non infrastructured components. With detailed knowledge of network topology, mobility, traffic patterns, and routing characteristics it is possible for a node to make better routing decisions that will enhance performance, and provide improved characteristics.
