Cooperation for Secrecy in Wireless Networks
The growth of wireless networks has been considerable over the last decades. Due to the broadcast nature of these networks, security issues have taken a critical role in today’s communications. A promising direction towards achieving secure communications is information theoretic secrecy, which is an approach exploiting the randomness of the channels to ensure secrecy. Based on this approach, t...
متن کاملCellular Systems and Infrastructure-Based Wireless Networks
Infrastructure-based wireless networks have base stations (access points). Advantages over Ad-hoc networks : efficiently utilize network resources. single-hop routes, results in : lower delay and loss higher data rates Examples : Wireless LANs, paging systems, and cellular phone systems.
متن کاملCache-Aided Combination Networks with Secrecy Guarantees
In this paper, we study a cache-aided combination network, where a layer of relay nodes connects a server to a set of end users, under three different secrecy requirements. Both the relays and the end users are equipped with caches. First, we consider secure delivery where we require that an external entity must not gain any information about the database files by observing the transmitted sign...
متن کاملCooperation in clustered cellular systems
The performance limitations of conventional cellular wireless networks in terms of throughput and coverage are by now well recognized. This is due to extensive deployment of 2G and 3G systems, and has stimulated the search for new approaches to alleviate these drawbacks. A key technology that has been identified to fulfill this goal is cooperation, to be employed at either the base station (BS)...
متن کاملModeling Cooperation between Nodes in Wireless Networks by APD Game
Cooperation is the foundation of many protocols in wireless networks. Without cooperation, the performance of a network significantly decreases. Hence, all nodes in traditional networks are required to cooperate with each other. In this paper, instead of traditional networks, a network of rational and autonomous nodes is considered, which means that each node itself can decide whe...
