A consideration on mobility and connectivity in multi-hop wireless networks

摘要

This report considers effects of mobility on performance of multi-hop wireless networks. The purpose of this report is to characterize relation between mobility and property of multi-hop wireless networks. This report pays attention to cellular networks with multi-hop networking, which is a countermeasure to the dead spot problem. This report considers the probability that a mobile node moving along a street loses connection to the base station within some time period after entering a dead spot. This probability is evaluated for some different mobility patterns, and the effects of difference between the mobility patterns on the call dropping probability are characterized. This report also considers how to numerically analyze the probability and how to estimate the probability considering some mobility patterns.
