Abstract
Handoff management plays an important role in next generation wireless network for providing the Quality of Service to the mobile users. Wireless Mesh Network (WMN) is the most promising and cost-efficient next generation wireless network for providing large-scale internet based wireless access. The Intergateway handoff is a major concern to guarantee continuous communications in Internet-based Wireless Mesh Networks (WMN). The previous system focus on intragateway handoff designed for single-hop wireless access network that supports only low handoff delay but there is no consideration for reducing the long handoff delay in WMNs due to the existence of multi-hop wireless links. In this paper, we are reducing the long handoff delay factor by proposing a channel splitting technique in multihop wireless link. By using channel splitting technique, the handoff delay in WMNs is guaranteed and channel utilization is improved. The data traffic is reduced and hence high throughput is achieved. The NS2 simulated results shows that handoff performance can be improved by our proposed handoff technique.
