Meshscan: A Fast And Efficient Handoff Scheme For Ieee 802.11 Wireless Mesh Networks, Yin Chen Apr 2010

Meshscan: A Fast And Efficient Handoff Scheme For Ieee 802.11 Wireless Mesh Networks, Yin Chen

Masters

As a next generation network solution, Wireless Mesh Networks (WMN) provides fast Internet access to a large area, which is from university campus to city scale. In order to provide an uninterrupted Internet experience to a mobile client, a process called handoff is required to maintain the network connection from one Mesh Node (MN) to another MN. Ideally, handoff should be completely transparent to mobile users. A critical application like VoIP will require a handoff capability that transfers a call from one mesh node (MN) to another in less than 50 msec. However the current IEEE 802.11 standards do not …


Feasibility Of Using Passive Monitoring Techniques In Mesh Networks For The Support Of Routing, Chenzhe Zhang Jan 2010

Feasibility Of Using Passive Monitoring Techniques In Mesh Networks For The Support Of Routing, Chenzhe Zhang

Masters

In recent years, Wireless Mesh Networks (WMNs) have emerged as a promising solution to provide low cost access networks that extend Internet access and other networking services. Mesh routers form the backbone connectivity through cooperative routing in an often unstable wireless medium. Therefore, the techniques used to monitor and manage the performance of the wireless network are expected to play a significant role in providing the necessary performance metrics to help optimize the link performance in WMNs. This thesis initially presents an assessment of the correlation between passive monitoring and active probing techniques used for link performance measurement in single …
