Location Information Advertisement Method with Consideration of Mobility Direction in Wireless Mobile Ad Hoc Networks

Abstract (in Japanese) (See Japanese page) 
(in English) In a wireless mobile ad-hoc network, it is critical to determine a wireless multihop transmission route from a source wireless node to a destination one. In flooding--free ad-hoc routing protocols such as GEDIR, GPSR and COMPASS, a wireless multihop transmission route is determined for each data message. On receipt of a forwarded data message, an intermediate wireless node determines one of its neighbor wireless nodes as its nexthop one and forwards the data message to it. Here, location information of not only neighbor wireless nodes but also the destination wireless node is required. In DREAM, all wireless nodes keep location information of all wireless nodes. When a wireless node moves, it advertises its new location information. For reduction of communication overhead, the up-to-date location information isadvertised to only nearer wireless nodes which are required to change its next-hop wireless node to transmit data messages to the moving node. Here, control messages for location information advertisement are transmitted equally to all directions. However, it is not required for wireless nodes which locate the same direction as the moving direction to receive the advertisement since their next-hop wireless nodes are not changed. This paper proposes a novel location information advertisement method where control messages with updated location information are forwarded only when di_erence of direction of moving wireless node is larger than predetermined threshold. By the proposed method, communication overhead for location information advertisement is expected to be reduced even though connectivity of the ad-hoc network is kept high.
