In this thesis we address the problem of safe substitutability in mobile component-oriented formalisms. We try to give a solution for different definitions of "safe" through a new notion of subtyping based on flexibility and observation. The aim is to have ...
Recently, there has been considerable discussion about new wireless technologies and standards able to achieve high data rates. Due to the recent advances of digital signal processing and Very Large Scale Integration (VLSI) technologies, the initial obstac ...
In multi-hop cellular networks, data packets have to be relayed hop by hop from a given mobile station to a base station and vice-versa. This means that the mobile stations must accept to forward information for the benefit of other stations. In this paper ...
With the convergence of internet and wireless communications, a plethora of new services will originate. A natural application for cellular radio networks is that of radiolocation, in which the mobile unit can be positioned based on the signals received at ...
Using location information to help routing is often proposed as a means to achieve scalability in large mobile ad-hoc networks. However, location based routing is difficult when there are holes in the network topology and nodes are mobile or frequently dis ...
This paper provides an asymptotic performance evaluation of network-based or multilateral positioning systems, where the times and/or angles of arrival of the signals traveling from a mobile station (MS) to a set of fixed stations (FSs) are used to estimat ...

NOVELTY - Secret data is generated in one terminal or user equipment. Secret or hash value of secret is displayed on display terminal (11) or user equipment and is entered on input element of other terminal or user equipment. Shared secret data is used to ...
For a cellular communication network, the loss in up-link bandwidth-efficiency resulting from power equalization is considered. Here power equalization refers to the operation of adjusting the transmit power of mobile units in such a way that the received ...
