Abstract
A mobile ad hoc network (MANET) is a collection of nodes that communicate over wireless channels and are capable of movement. A single-hop ad hoc network allows nodes that are within the same transmission radius (50-200meters), to communicate with each other. This limitation in transmission distance can be surmounted by multi-hop ad hoc networking. Such networking requires that ad hoc nodes serve an additional role as routers and must forward packets on behalf of each other. The increasing presence of wireless access points means that nodes in a MANET could have access to the wired network. This paper examines the potential benefits of allowing a node to choose a service from either its one-hop ad hoc neighbors or the wired network. The wired network is reached via an access point which could be multiple hops away. The service examined is that of authentication. The benefit of choosing the service provider is examined with respect to the frequency with which a service is accessed. The main contribution of this work is a set of experiments comparing the results of being able to choose where to obtain a service to that of getting the service from only ad hoc peers or an access point. The comparison evaluates service latency and network impact.
