A Random Access Protocol with Multi-Packet Reception for Infrastructure-Less Wireless Autonomic Networks

Abstract

A random access protocol with multi-packet reception (MPR) capability for infrastructure-less wireless autonomic networks is introduced and analyzed. In these networks mobile nodes may communicate with each other directly without a central entity (base station), where each mobile node either will be in a transmitting mode or in a receiving mode or in an idle mode. The throughput per node and the packet retransmission probability depend exclusively on the MPR capability and the ratio of the transmission probability and the receiving probability of each mobile node. For a given ratio of the transmission probability and the receiving probability of each mobile node, throughput-delay performance increases with the increase of MPR capability. In the proposed infrastructure-less networks, mobile nodes can control the network traffic very precisely by controlling the three parameters. These three parameters are transmission probability, receiving probability and idle mode probability of each mobile node. Since each mobile node can control the network traffic very precisely to obtain the maximum throughput, the network is autonomic, i.e., self-optimizing. The optimum transmission probability of each mobile node to obtain the maximum throughput is evaluated. The throughput utility increases with the increase of MPR capability. On the other hand, the cost per mobile node also increases with the increase of MPR capability. Therefore the MPR capability should be optimized to provide reasonable trade-off between the throughput per node and the cost per mobile node. The results of this study may be used for a system design of an infrastructure-less contention-based multiple access schemes with MPR capability.

Energy-Efficiency Optimization With Model Convexification for Wireless Ad Hoc Networks With Multi-Packet Reception Capability

“…These protocols can be realized by using some physical-layer self-interference cancellation technologies such as radio frequency (RF) interference cancellation, digital cancellation, and antenna cancellation. From many successful application domains, such as unmanned aerial vehicle (UAV) networks [3], wireless ad hoc or autonomic networks [7], [8], and wireless multimedia networks [9], [10], it is witnessed that the full-duplex radios and (Corresponding author: Daxin Tian) multi-packet reception capability can bring great benefit to communication and networking systems in terms of system-level performance improvement. Hence, this technical paradigm has received much research attention.…”

“…This integration poses an important challenge for system design and optimization. In particular, the impact of concurrent interferences on the quality of received signal cannot be fully ignored, even when the network nodes are equipped with advanced self-interference technologies [3], [7], [8].…”
