Handoff Management Issues in Heterogeneous Wireless Network: A Review
نویسنده
چکیده
In this Paper, the study focuses on the various handoff management issues in Heterogeneous wireless network. A handoff scheme is essential to provide continuous connections whenever a mobile node moves from one coverage area of network to another. The handoff management issues consist of finding the appropriate time to perform the handoff depending upon RSS (received signal strength), traffic, bandwidth, velocity, channel conditions and cost etc. A handoff management scheme is also studied considering the current research into multicast mobility handoff between 3G mobile and WLAN. Finally, a scheme supporting group mobility is studied having a protocol for mobile groups that allows a single node to perform handoffs on behalf of all group members.
