Abstract:
Problems may occur in ad hoc network when packets are being multicast. Global routing structure may also produce extra processing cost because the dynamic topology will introduce frequent exchange of routing vector or routing state between nodes. To deal with these problems an improved multicast protocol based on routing grid is designed to ensure that the multicast packets could be sent to destination through dynamic topology network using multicast routing grid.
