“…MS-MAC has the same packet format as S-MAC, while DE-ASS [1] adds multiple schedule information in the SYNC packet at the border node. The packet structures of other MAC protocols designed to support mobility [5], [6] are more complicated than those of S-MAC. The design of our mechanism is based on the S-MAC format.…”

“…In the proposed MS-MAC protocol [5], a change in the radio signal level of received SYNC messages is used as an indication of a mobile's presence. Although this method does not provide a high level of accuracy, it is effective in our mechanism, which is described in more detail in [5].…”

Although mobile applications are an essential characteristic of wireless sensor networks, most existing media access control (MAC) protocols focus primarily on static networks. In these protocols, fixed periodic neighbor discovery and schedule updating are used to connect and synchronize neighbors to provide successful data transmission; however, they cannot adapt to mobile speed variation and degrade the network performance dramatically. In this paper, we propose a mobile-supporting mechanism for MAC protocols, in which the decision to update the neighbors of a mobile node is made adaptively according to the mobile speed. Analysis and simulation results demonstrate that the mechanism efficiently avoids the disconnection of a mobile node from its neighbors and achieves a better performance as compared with fixed periodic neighbor discovery.
