ALOHA-type protocols became a popular solution for distributed and uncoordinated multiple random access in wireless networks. However, such distributed operation of the Medium Access Control (MAC) layer leads to sub-optimal utilization of the shared channel. One of the reasons is the occurrence of collisions when more than one packet is transmitted at the same time. These packets cannot be decoded...
Machine-to-Machine (M2M), an emerging communications paradigm, is a facilitator of data flows between machines used, e.g., in mission-critical applications. Focusing in this paper on embedded multihop M2M implementations with myopic routing, a prime design aim is to jointly minimize energy expenditure and the end-to-end delay whilst not jeopardizing the network's operational reliability. We thus evaluate...
The distributed queuing with collision avoidance (DQCA) medium access control (MAC) protocol has been presented in the literature as a high-performance protocol for uplink traffic in WLANs. Previous works regarding DQCA are focused on the operation of a single cell, where no interaction with neighboring sites is considered. In this paper, we define specific handoff functions (channel sensing, discovery...
