Data Farming, network applications and approaches to integrate network analysis and processes to the data farming paradigm are presented as approaches to address complex system questions. Data Farming is a quantified approach that examines questions in large possibility spaces using modeling and simulation. It evaluates whole landscapes of outcomes to draw insights from outcome distributions an...

Organic farming which experienced a constant rise over the last two decades is a system based on sustainability and on a concept tending towards functional integrity. Legislation as well as the wish to produce separately from conventional farming raise the question whether organic farming should be conducted completely apart from conventional farming or not. This paper discusses the aspects tha...

We study the Online Steiner Tree Leasing (OSTL) problem, defined in a weighted undirected graph with a distinguished root node r. There is a known set L of available lease types, where each type ` ∈ L is characterized by its duration D` and cost factor C`. As an input, an online algorithm is given a sequence of terminals and has to connect them to the root r using leased edges. An edge of lengt...

In mobile ad hoc networks (MANETs) many partial failures are the result of temporary network partitions due to the intermittent connectivity of mobile devices. Some of these failures will be permanent and require application-level failure handling. However, it is impossible to distinguish a permanent from a transient failure. Leasing provides a solution to this problem based on the temporal res...

This paper investigates the optimal length of lease period and maintenance policy for leased equipment. In order to have steady revenue, the lessor (owner) of equipment may provide a discount to encourage the lessee (user) to sign a contract with a longer lease period. However, as the lease period increases, the maintenance cost also increases due to the deterioration or usage of the equipment....

The paper proposes a new scheme for on-demand allocation of global IP addresses to hosts of an autonomous network. Such a scheme is needed in order to overcome the problem of IP address exhaustion. According to the new scheme, each host of the autonomous network is assigned a xed local address which appears in the source eld of all the IP datagrams the host sends and in the destination eld of a...
