A utopian political theory (UPT) can emerge from the analysis of borders. The significant increase in human mobility between State-borders constitutes the empirical referent distinguishing our “Utopian Age” from others in the past, as historical examples of UPT have not dealt with either the issue of human mobility or the topic of “Migration without Borders”. We start with a brief introduction ...

In ad hoc mobile networks nodes typically communicate over wireless channels and are capable of movement. These are networks that support multihop communication and can be formed on a temporary basis. This paper evaluates a solution that allows mobile nodes to access the wired Internet and roam from base station to base station. The solution is based on the extension of Mobile IP capabilities t...

In this paper, a new hierarchical multihop routing algorithm and its performance evaluation is presented for fully dynamic wireless networks. The routing algorithm operates on a virtual topology obtained by partitioning the routing information for mobile terminals and mobile base stations into a hierarchical, distributed database. Based on the virtual topology, each mobile base station stores a...

Hunter–gatherers mobility regimes are often treated as discrete adaptive strategies. Here we present a model of forager mobility which treats collectors and foragers as two ends of a continuous spectrum. We s...

this paper presents optimal control method to path planning of mobile robots with flexible joints. dynamic equations are derived and additional kinematic constraints are used to solve the extra dofs arose from base mobility. then with modeling the elasticity at each joint as a linear torsinal spring, the set of equations are formed. the hamiltonian function is formed and the necessary condition...

Integration of vehicular ad hoc network and fixed IP network is important to provide Internet connection and mobile data service for vehicles. However, the unique characteristics of vehicular networks, such as linear topology and constrained movements of vehicles, are not considered in the conventional mobility management schemes. Using conventional schemes, unnecessary management messages are ...

In this paper we consider the problem of monitoring detecting separation of agents from a base station in robotic and sensor networks. Such separation can be caused by mobility and/or failure of the agents. While separation/cut detection may be performed by passing messages between a node and the base in static networks, such a solution is impractical for networks with high mobility, since rout...

In a typical wireless local loop (WLL) system, a user can only access the wireless services at "xed locations. This paper proposes a private branch exchange (PBX) based mobility manager for WLL, which allows users to receive wireless service at any locations within the WLL service area. We show how the mobility manager can be implemented in a PBX environment where the base stations are connecte...

Mobility of a phone within a cellular network or of a computer within the Internet has to be managed by the respective network infrastructure: Routes to and from a mobile device have to be changed. In order to base mobility management of future cellular networks on IP, the Internet Protocol, various proposals like Mobile IP are currently being discussed. In this paper, we develop a simple model...

In this paper, the mobility of software processes, a novel concept, is proposed. It is defined as the structural change in a software process resulting from interactions among linked process elements. The concept addresses the essential change in a software process which brings a high variability and unpredictability to process performance. Three categories of mobility that lead to the structur...
