Throughput-Delay Trade-off for Hierarchical Cooperation in Ad Hoc Wireless Networks

, 2008
Hierarchical cooperation has recently been shown to achieve better throughput scaling than classical multihop schemes under certain assumptions on the channel model in static wireless networks. However, the end-to-end delay of this scheme turns out to be

Trajectory Optimisation for UAV Data Collection in IoT‐Based WSN: A Lévy Flight‐Based Approach

IET Smart Cities, Volume 8, Issue 1, January/December 2026.
In large‐scale IoT and WSN deployments, data transmission to base stations is often limited by restricted network coverage, and drones can help extend connectivity by collecting data from cluster head nodes. This work proposes an energy‐efficient drone‐assisted data collection approach that jointly optimises system costs and energy consumption, taking ...

A Systematic Review of VANET Routing Protocols for Intelligent Transport Systems (ITSs)

Journal of Advanced Transportation, Volume 2026, Issue 1, 2026.
The swift improvement of wireless communication technology has aided the creation of vehicular ad hoc networks (VANETs) as a revolutionary option for the realization of intelligent transportation systems (ITSs). VANETs facilitate seamless communication between vehicles and infrastructure (V2I) and among the vehicles themselves (V2V). These networks can

Request-TDMA

, 1995
This paper describes a cellular multiple-access scheme based on TDMA for multimedia communication networks. The scheme proposes an admission control of two different multimedia application stream types: real-time and non-real-time. We do not consider interference between cells.

A Systematic Literature Review on Auction Mechanisms: Insights From the Last Decade and Future Directions

Journal of Economic Surveys, Volume 39, Issue 5, Page 1971-1998, December 2025.
ABSTRACT This study reports the results of a systematic literature review on auctions mechanism. Auctions are a very popular practice employed in many fields but does not exist a research that investigates the use of auctions under a cross‐disciplinary approach. This work is focused on analyzing which are the areas where auctions are mostly adopted and
