Abstract
Multipacket reception (MPR) is the capability of simultaneous decoding of more than one packet from multiple concurrent transmissions. Continuous investigations on increasing the reception capability are giving new scientific contributions. In this paper, we provide an overview of MPR-related research work covering (1) the theoretically proved impacts and advantages of using MPR from a channel perspective to network capacity and throughput; (2) the various technologies that enable MPR from transmitter, transreceiver, and receiver perspectives; (3) previous work on protocol improvement to better exploit MPR. Indeed, MPR approaches have been applied in modern wireless mobile systems but the focus of this paper is to discuss MPR in random access wireless networks. Using MPR in such multihop environments calls for new adaptation on protocols, especially a cross-layer approach. To this end, we detail a scheduling method that targets full utilization of MPR capability.
Highlights
In the past decade, wireless technologies have become key technologies, offering mobile and flexible communications for industries, enterprises and individuals
We find an increase of confusion in Multipacket reception (MPR) techniques and how to use MPR techniques
They showed that λ(n) = Θ(R(n)(1−2/α)/n1/α) bits per second constitutes a tight upper and lower bound for the throughput capacity of random wireless ad hoc networks, where α > 2 is the path loss parameter in the physical model, n is the total number of nodes in the network, and R(n) is the MPR receiver range
Summary
Wireless technologies have become key technologies, offering mobile and flexible communications for industries, enterprises and individuals. The notion of Multipacket reception (MPR) was introduced in some of these works [4, 5] and is applied in telecommunication systems It was in [6] that MPR was first discussed for the slotted Aloha protocol and for a random access wireless network. Simultaneous transmissions lead to useless collisions and a significant degradation of network throughput, and retransmissions often make the situation even worse All these disadvantages are related to the receiver capability of Single Packet Reception (SPR). One of the purposes of this survey is to clarify MPR enabling techniques by classifying them into transmitter, trans-receiver, and receiver perspectives (Section 3) We expect this survey would help researchers working in related areas to make more realistic hypothesis with the MPR model. We will discuss major work on MAC and networking protocol design to exploit MPR (Section 4) and in the same part we detail a scheduling method that targets full utilization of MPR capability using a cross-layer approach
