“…1 depicts the ADORP as a function of the ALOHA transmission probability, for a system with a path loss exponent of 3.3. The figure compares the performance of the SO scheme to the performance of two previously published geographical routing schemes, the Nearest-neighbor scheme and Most-Progress-within-a-Radius (MPR) scheme [14]. As can be seen, the proposed SO scheme significantly outperforms the two other routing schemes.…”

In this paper, we propose a novel distributed routing scheme in multihop wireless adhoc networks. We assume that the nodes are distributed according to a Poisson-Point-Process (PPP), and employ stochastic-geometric tools to derive a novel routing metric. The proposed Statistically-Optimal (SO) scheme, works in a decentralized manner in which the next relay selection exploits knowledge on the geographical location of each possible relay and on the instantaneous channel gain (fading diversity). The SO scheme maximizes the expected routing performance metric given the channel gains to the potential relays and their locations. Simulations results demonstrate that the SO scheme outperforms previously published schemes, and achieve performance which is close to the upper bound on ALOHA performance. Furthermore, the implementation of the suggested SO scheme is very simple, and the metric evaluation requires only minimal computations.

“…Accordingly, the spatial density of potential D2D transmitters can be determined as (1 − ρ 1)λu. Therefore, the density of successful D2D links can be approximated as the density of active D2D transmitters or active D2D receivers, and then (3) can be obtained (Theorem 2 in [14]). …”

Different from previous works, in this paper, we adopt D2D communication as a routing extension to traditional cellular uplinks thus enabling a two-hop route between a user and the serving BS via a D2D relay. Specifically, a BS establishes a cellular link with a mobile user only if the pilot signal strength received from the user is above a specified threshold; otherwise, the user may establish a D2D link with a neighboring user and connect to a nearby BS in a two-hop manner. We present a stochastic geometry based framework to analyze the coverage probability and average rate in such a two-hop multi-channel uplink cellular network where mobile users adopt the fractional channel inversion power control with maximum transmit power limit. As validated by extensive numerical results, the developed framework enables network designers to efficiently determine the optimal control parameters so as to achieve the optimum system performance. Our results show that employing D2D link based two-hop connection can significantly improve both the network coverage and average rate for uplink traffic.

“…The basic problem of whether direct transmission or multihop routing strategy increases the performance in multi-hop wireless networks is investigated in the literature from several aspects [12,14,28,8,21,22,2,19], however none of these studies consider the effect of traffic arrival distributions. These studies assume either saturated traffic sources, where the nodes always have a packet waiting to be transmitted (due to capacity related concerns with optimal link scheduling and optimal routing assumptions), or assume the Poisson traffic arrival distribution only, omitting the effect of different traffic arrivals on the performance results.…”

The basic problem of whether direct transmission or multihop routing increases goodput in multi-hop wireless networks still lacks investigation from many aspects. This article, approaches this problem by considering the effect of different traffic arrival distributions on the choice of routing strategy for enhancing goodput of IEEE 802.11 DCF based multi-hop wireless networks under hidden terminal existence. Different traffic arrival distributions; including Poisson, constant bit rate (CBR), Pareto and Exponential are considered, relaxing the generally adopted Poisson assumption, for various data rates over a wide range of traffic loads extending from unsaturated to saturated traffic loads.The goodput performance for all traffic arrival distributions is found to be dependent on the traffic load in multihop networks. Of the four traffic models used, the network achieved the best goodput with Pareto and Exponential arrival distributions for light traffic loads, where CBR performs slightly better under heavy loads. The results suggest that a traffic load-aware pre-control mechanism on the traffic arrivals to the IEEE 802.11 MAC layer might provide significant goodput gains in multi-hop wireless networks.
