Abstract:

Ahoy, a protocol to perform local service discovery in ad-hoc networks has been designed. The protocol has been implemented in a discrete-event simulator to study its performance in case of a multihop mobile ad-hoc network. Especially the effect of mobility on the network load and the probability of finding services is investigated. Experiments show that the load caused by advertisement messages is very low, even when the mobility is increasing. For low speeds the percentage of found services is close to the maximum possible, while even at high speeds the probability of finding a service is still reasonable.
