Various embodiments of the invention provide a contributory value (rand) (alternatively the contributory value is referred to as a random field or a rand), according to which a seed can be commonly created so that the seed is configured to be similar for all apparatuses. In the apparatus discovery phase this reduces the need for making several calculations to define whether an apparatus is known or not. A bloom filter can embody as an example of a data structure filter. If the values, e.g. the fields, are put together with a filter, it can be estimated by certain probability whether there are any known apparatuses or not. This estimation can be performed even by a single calculation or processing step. In various embodiments it should be noted that apparatuses may alternatively be referred to as devices as well. |
