“…However, the choice of this data rate normally does not affect the routing result as long as it is the same for all routes. This is shown in the case study in Section V, where after further derivation of (8), the data rate is removed completely from the cost function. However, if the result of routing does depend on the choice of the data rate in (8), the routing process should be performed based on the current data rate, or on the one that is assigned by the network and thus will be employed in the forthcoming transmission time intervals (TTIs).…”

“…As a result, these algorithms are not suitable for MCNs. In recent years, routing in the context of MCNs has become a research issue, and a few algorithms have been proposed so far, e.g., location-based routing [4], path-loss-based routing [7], transmission-power-based routing [8], and congestion-based routing [3]. These algorithms can, to some extent, solve the route selection problem in MCNs.…”

Abstract-Recently, the notion that a logical next step towards future mobile radio networks is to introduce multihop relaying into cellular networks, has gained wide acceptance. Nevertheless, due to the inherent drawbacks of multihop relaying, e.g., the requirement for extra radio resources for relaying hops, and the sensitivity to the quality of relaying routes, multihop cellular networks (MCNs) require a well-designed radio resource allocation strategy in order to secure performance gains. In this paper, the optimal radio resource allocation problem in MCNs, with the objective of throughput maximization, is formulated mathematically and proven to be NP-hard. Considering the prohibitive complexity of finding the optimal solution for such an NP-hard problem, we propose an efficient heuristic algorithm, named integrated radio resource allocation (IRRA), to find suboptimal solutions. The IRRA is featured as a low-complexity algorithm that involves not only base station (BS) resource scheduling, but also routing and relay station (RS) load balancing. Specifically, a load-based scheme is developed for routing. A mode-aware BS resource-scheduling scheme is proposed for handling links in different transmission modes, i.e., direct or multihop. Moreover, a priority-based RS load balancing approach is presented for the prevention of the overloading of RSs. Within the framework of the IRRA, the above three functions operate periodically with coordinated interactions. To prove the effectiveness of the proposed IRRA algorithm, a case study was carried out based on enhanced uplink UMTS terrestrial radio access/frequency-division duplex with fixed RSs. The IRRA is evaluated through system level simulations, and compared with two other cases: 1) nonrelaying and 2) relaying with a benchmark approach. The results show that the proposed algorithm can ensure significant gains in terms of cell throughput.Index Terms-Cellular networks, fixed relay stations (RSs), multihop, radio resource allocation (RRA).

“…In [48], a centralized SIR/Power Routing Algorithm similar to Dijkstra's algorithm was proposed in an attempt to minimize a network cost function. Research was also performed by Kusuma in which he presented a centralized routing algorithm that found the minimum power routing paths for all nodes in the network [33]. However it is not realistic to assume that an entire view of the network is known and therefore a distributed routing algorithm is required.…”

However, multihop cellular networks still suffer from large amounts of interference surrounding the base station because all traffic either emanates or is destined to the base station making it the capacity bottleneck. To resolve this problem, we propose a novel architecture called the autonomous infrastructure multihop cellular network where users can connect their mobile terminals to the backbone network giving them the functionality of an access point. Access points receive traffic from other terminals and send it directly onto the backbone, as would a base station. This reduces the traffic handled by the base station and increases network capacity. Our analysis and simulations show that in autonomous infrastructure multihop cellular networks, the SINR at the base station ii is higher, the power consumption is lower and the coverage is better than in normal multihop cellular networks.Access points require parameters like their transmission range to be adjusted autonomously to optimal levels. In this thesis, we propose an autonomous pilot power protocol. Our results show that by adjusting a parameter within the protocol, a required coverage level of terminals can be specified and achieved without knowledge of the location or density of mobile terminals. Furthermore, we show that the protocol determines the transmission range that is optimal in terms of SINR and power consumption that achieves the required coverage while effectively eliminating the bottleneck that existed at the base station.iii

In a high-speed vehicular scenario, due to vehicle penetration loss (VPL) and fast signal fluctuations, frequent handovers occur, which results in more battery consumption. So power saving is a critical concern in high-speed wireless networks. In the past, moving relay (MR)-based heterogeneous network (HetNet) models were proposed and studied to overcome the effect of VPL, but the issue of power saving has not been studied till now for vehicular HetNet.
