We present a new distributed algorithm for creating and maintaining power-efficient topologies in a wireless network. The wireless nodes establish links to neighbouring nodes in a self-organizing fashion. The protocol is designed to first create a connected topology and then iteratively search for better links to reduce the overall power consumption. First results from simulated experiments wit...

Since wireless sensor networks (WSN) as ad hoc networks do not have infrastructures and their topologies change dynamically, network nodes should be able to take suitable decisions without needing to know the network topology. One of these decisions is selecting the appropriate policy for service distribution of the whole network. The method of service distribution in the network is uniform by ...

This paper considers the characteristics of WAP traffic. We start by constructing a model of WAP traffic based on a number of user scenarios. One traffic characteristic which is of particular interest in network dimensioning is the degree of self-similarity, so the paper looks at the characteristics of aggregated traffic with WAP, web and packet speech components to estimate its self-similarity...

We describe and discuss an affordable way to spread huge software without relying on internet connection, via the use of self-replicating live USB keys.

This paper introduces a framework for designing self-organising wireless sensor networks for assisted living. The topology of these networks is studied and definition of self-organisation is given. Here, we propose paradigms and explain “local” and “global” network properties. In conclusion, the self-organised network function for the wireless health-care networks is designed. Simulation result...
