Connectivity as a Fundamental Characteristic of Mobile Ad Hoc Networks

In this chapter, the idea of formulating the node connectivity into a form suitable for the purpose of monitoring the dynamic of any given node pair was proposed. It had been able to show that the node connectivity time constitutes the length of time where node-pairs are connected and communication sessions can be established. By analytical calculation and simulation, the node connectivity time depends on the relative velocity of the node-pair. It shows that there is an upper limit and a lower limit for the connection time. Between these limits, communication sessions can be carried out. In order to monitor the quality of connection between a node-pair and for the whole route which is made up of a collection of node-pairs, npem, npcm, and nci are introduced. The nci is shown to be a viable way to estimate the quality of node-pair connection in terms of its timeliness. The index, nci, could be used as one of the metrics to identify and select the best path to the destination.
