Abstract
With the prosperity of the internet network, there are more and more wireless
mobile devices producing, so people are greater and greater to the demand for internet
access at any time. Some studies that integrate the Ad Hoc network into the internet in
order to achieve the aim of the internet access on the go. Among them someone
proposes that there is a part of Ad Hoc network MNs that can connect with BS, these
MNs can be selected to act as Internet Gateway(IG), other MNs which can not
connect with BS will convey the date to the internet through the IG. But IG itself is a
MN, so IG switching is the most important factor to influence the performance of
network, because at this switching time, Ad Hoc network does not connect with
internet, all MNs must suspend transmission. If this swtiching time is too long, that
will cause the efficiency of the network to glide seriously. Therefore, we propose
some improvement methods and combine L2 trigger to reduce the delay time, and we
utilize AR and BG selection to determine new DG produced to reduce DG switching
times.
