When searching for resources on networks, the system oftendepends on the broadcast or multicast mechanism to acquire theinformation, which usually results in large overhead. It will be aserious problem in ad-hoc wireless networks, where the bandwidth islimited and each node moves arbitrarily and acts not only as a hostbut also as a router. Therefore, it will greatly rely on broadcastor multicast mechanism to search the resources. This work presentsan efficient anycasting scheme in ad-hoc wireless networks. Thescheme can be used to reduce the request messages, decrease theoverhead of response received from duplicate packets, and balancethe load of ad-hoc wireless networks. Furthermore, our scheme alsosupports any K services; it can attain the backup or faulttolerance purpose. Because our scheme is based on the virtualbackbone, it is also a scalable protocol for ad-hoc wirelessnetworks.
