Characterization of Inaccessibility in Wireless Networks: A Case Study on IEEE 802.15.4 Standard

Free registration required

Executive Summary

Wireless technology has been seen as the communication technology of the future. One of many challenges is the support for predictability and time-bounded communications over this technology. In this way, the control of temporary partitions, called inaccessibility, is of fundamental importance. For this reason, this paper makes a characterization of inaccessibility in wireless networks and describes an exhaustive study about it on IEEE 802.15.4 wireless standard. The knowledge of inaccessibility incidents and their duration is a first step to define means to control network partitioning and therefore to form a basis for supporting real-time communications over wireless technology.
