On the Capacity of Hybrid Wireless Networks
We study the throughput capacity of hybrid wireless networks. A hybrid network is formed by placing a sparse network of base stations in an ad hoc network. These base stations are assumed to be connected by a high-bandwidth wired network and act as relays for wireless nodes. They are not data sources nor data receivers. Hybrid networks present a tradeoff between traditional cellular networks an...
متن کاملContent-centric Wireless Networking
Mobile devices, such as smartphones, provide a readily available basis for mobile offloading [2] and mobile applications [3]. Given the density of devices in urban scenarios, the key challenge is to discover and connect to devices participating in the same application, i.e., that provide or request content of interest. However, the network-centric design of 802.11 requires instantiation of and ...
متن کاملOn the Throughput Capacity of Wireless Information-Centric Networks
Wireless information-centric networks consider storage one of the network primitives, and propose to cache data within the network in order to improve latency to access content and reduce bandwidth consumption. We study the throughput capacity of an information-centric network when the data cached in each node has a limited lifetime. The results show that with some fixed request and cache expir...
متن کاملContent Dissemination Protocols in Hybrid Wireless Networks
Wireless hybrid networks have become quite popular with the evolution of several devices with multiple networking interfaces. Each of these interfaces (and the associated networks) have significantly different characteristics, hence it is important to understand how best to utilize and operate in the presence of multiple networks. Smartphones are a popular example of devices with multiple netwo...
متن کاملThroughput-Delay Tradeoffs in Content-Centric Wireless Networks
We study the throughput and delay characteristics of wireless networks based on an information-centric network architecture, where users are mainly interested in retrieving content stored in the network, rather than in maintaining source-destination communication. Nodes are assumed to be uniformly distributed in the network area. Each node has a limited-capacity content store, which it uses to ...
