Executive Summary

The issue of supporting mobility in Wireless Sensor Networks is recently attracting increasing attention within the research community as new-born application scenarios require the deployment of hybrid network architectures composed of fixed and mobile sensor nodes. In this paper, the authors address the problem of mobility management in WSNs by proposing a tree-based routing protocol able to support mobile sensor nodes. Distinctive features of the proposed routing solution are the provision of bi-directional uplink/dowlink connectivity to mobile sensor nodes, the use of proactive procedures to speed up the association/re-association phase, a reduced impact of the signalling overhead to manage node mobility by resorting to "Local" handover management procedures.
