text: This paper is focused on a discussion of parameters and heuristics that are expected to assist multihop routing in becoming more sensitive to node mobility. We provide a discussion concerning existing and a few proposed parameters. Moreover, the work also discusses two new heuristics based on the notion of link duration. The heuristics are compared based on a meaningful set of scenarios that attain different mobility aspects.
  @cite_0: This paper introduces a novel mobility-aware routing protocol (MARP) for mobile, cognitive ad-hoc networks. Traditional routing protocols trigger the routing updates after the nodes detect the route failure. Even if the link condition is getting worse which means the link is likely to break in the future, the nodes will still transmit the packets along the current path. MARP uses cognitive techniques to predict when the link is likely to break so that it can inform the previous hop to trigger the routing updates before the link breaks. In this way, the nodes are aware of the physical topology changes. Based on simulation results, MARP can increase overall performance of the network significantly.
summary: A second category of work that tries to make routing more sensitive to node mobility relates to throughput variation measurement as a way to determine node mobility. For instance, Suyang and Evans have used the slope of change of throughput in a link vs. the link load to estimate topology changes @cite_0 . Based on history, through throughput monitoring, a decrease, according to Suyang and Evans, means that there is a true change in the physical topology. They have attributed the changes to increase in the node distance and increase in interference. Even with good attributes of avoiding interference and detecting mobility collectively, node mobility individually has attributes that have not been addressed. Nodes may exhibit movement that does not necessarily impact the route stability.
