The recent growth of Wireless Internet enables various services including multimedia Data and IEEE802.11 Standard comes into wide use in previous wire Network. However, Handover of IEEE802.11 manages autonomously and indecently by each client without priori information of the arrived network. This scheme can minimizes management overhead but increases handover delay and degrades QoS of various applications like group communication. In this paper, We propose new scheme to reduce handover delay. This scheme is compatible with IEEE802.11 and applicable to IEEE802.11 to use the group communication and the IAPP scheme. Proposed scheme minimizes gathering time of scanning APs in arrived Network by exchanging Node Report Messages between sender and Mobile nodes. therefore, Mobile Nodes take priori information of APs in Arrived Network in advance. Simulation results show that proposed scheme reduces handover delay and channel scanning delay.
Abstract
The recent growth of Wireless Internet enables various services including multimedia Data and IEEE802.11 Standard comes into wide use in previous wire Network.

This scheme can minimizes management overhead but increases handover delay and degrades QoS of various applications like group communication. In this paper, We propose new scheme to reduce handover delay. This scheme is compatible with IEEE802.11 and applicable to IEEE802.11 to use the group communication and the IAPP scheme. Proposed scheme minimizes gathering time of scanning APs in arrived Network by exchanging Node Report Messages between sender and Mobile nodes. therefore, Mobile Nodes take priori information of APs in Arrived Network in advance. Simulation results show that proposed scheme reduces handover delay and channel scanning delay.
