Abstract

The modern paradigm of Mobile Computing is playing a vital role in everyday life, both in terms of comfort and security. Unfortunately, mobility causes undesired phenomena for wireless communications, so several actions need to be take into account, in order to overcome the possible degradations introduced by mobility effects. OSI layer 3 approaches have been widely investigated in literature regarding the optimization of the whole network performance, while in this article we focus our attention on the analysis of the entropy trend for a mobile environment. The effects of mobility on entropy are investigated, as well as a new approach for predicting entropy evolution over time. In a mobile scenario, so in the considered context, the mobility entropy is able to optimise some key aspects of wireless communications, such as nodes stability, channel failures, and routing costs. In order to state the effectiveness of our proposal, many simulation campaigns have been carried out, taking into account the movement of the real nodes, confirming our assumptions.
