three-node network (B3NN) composed of a source node (SN), a

instantaneous channel fading values may be directly mapped to
a specific point in this 3D channel space. The BOR scheme then
relies on the position of this point to select the most appropriate
channel for its transmission. Both the energy dissipation and the
outage probability (OP) are investigated for transmission in this
network. The results show that when the system is operated at a
normalized throughput of 0.4 packet/TS, the energy dissipation
was reduced by 24.8% to 77.6% compared to three different
benchmark schemes. Alternatively, our technique is capable of
reducing the OP by 89.6% when compared to conventional opportunistic
routing. As in all buffer-aided system, the performance
improved with the cost of higher packet delay, which is also
studied.

Abstract

In this contribution, we propose and study a bufferaided
opportunistic routing (BOR) scheme, which combines the
benefits of both opportunistic routing and multihop diversity
(MHD) aided transmissions. It was conceived for a buffer-aided
three-node network (B3NN) composed of a source node (SN), a
buffer-aided relay node (RN) and a destination node (DN). In this
network, there are three channels namely the SN-RN, RN-DN
and SN-DN channels. The key motivation is that we are aiming
for activating the specific channels requiring a recuded energy
dissipation. In order to study this problem, a three-dimensional
(3D) transmission activation probability space (TAPS) is proposed,
which is divided into four regions representing each of the three
channels plus an outage region. In a specific time slot (TS), the
instantaneous channel fading values may be directly mapped to
a specific point in this 3D channel space. The BOR scheme then
relies on the position of this point to select the most appropriate
channel for its transmission. Both the energy dissipation and the
outage probability (OP) are investigated for transmission in this
network. The results show that when the system is operated at a
normalized throughput of 0.4 packet/TS, the energy dissipation
was reduced by 24.8% to 77.6% compared to three different
benchmark schemes. Alternatively, our technique is capable of
reducing the OP by 89.6% when compared to conventional opportunistic
routing. As in all buffer-aided system, the performance
improved with the cost of higher packet delay, which is also
studied.
