Enabling Cooperative Ad Hoc Networks under Noise

Non-cooperative Forwarding in Ad-Hoc Networks

A wireless Ad-hoc network is expected to be made up of energy aware entities (nodes) interested in their own perceived performance. An important problem in such a scenario is to provide incentives for collaboration among the participating entities. Forwarding packets of other nodes is an example of such a collaboration. However, it may not be in interest of a node to always forward the requesti...

Cooperative Caching in Ad Hoc Networks

Terminal’s latency, connectivity, energy and memory are the main characteristics of today’s mobile environments whose performance may be improved by caching. In this paper, we present an adaptive scheme for mobile Web data caching, which accounts for congestion of the wireless network and energy limitation of mobile terminals. Our main design objective is to minimize the energy cost of peer-to-...

Cooperative data collection in ad hoc networks

This paper studies the problem of data gathering in multi-hop wireless ad hoc networks. In this scenario, a set of wireless devices constantly sample their surroundings and initiate report messages addressed to the base station. The messages are forwarded in a multi-hop fashion, where the wireless devices act both as senders and relays. We consider data gathering without aggregation, i.e. the n...
