“…The main drawback of this approach is that an additional omnidirectional antenna is required. Following the similar idea, an antenna array can work in a quasiomnidirectional manner by omnidirectional beamforming to perform neighbor discovery [182], [183]. However, wider beam means lower beamforming gain, thus causing shorter discovery range.…”

Antenna arrays have a long history of more than 100 years and have evolved closely with the development of electronic and information technologies, playing an indispensable role in wireless communications and radar. With the rapid development of electronic and information technologies, the demand for all-time, all-domain, and full-space network services has exploded, and new communication requirements have been put forward on various space/air/ground platforms. To meet the ever increasing requirements of the future sixth generation (6G) wireless communications, such as high capacity, wide coverage, low latency, and strong robustness, it is promising to employ different types of antenna arrays (e.g., phased arrays, digital arrays, and reconfigurable intelligent surfaces, etc.) with various beamforming technologies (e.g., analog beamforming, digital beamforming, hybrid beamforming, and passive beamforming, etc.) in space/air/ground communication networks, bringing in advantages such as considerable antenna gains, multiplexing gains, and diversity gains. However, enabling antenna array for space/air/ground communication networks poses specific, distinctive and tricky challenges, which has aroused extensive research attention. This paper aims to overview the field of antenna array enabled space/air/ground communications and networking. The technical potentials and challenges of antenna array enabled space/air/ground communications and networking are presented first. Subsequently, the antenna array structures and designs are discussed. We then discuss various emerging technologies facilitated by antenna arrays to meet the new communication requirements of space/air/ground communication systems. Enabled by these emerging technologies, the distinct characteristics, challenges, and solutions for space communications, airborne communications, and ground communications are

Mobile Ad-hoc Networks (MANETs) is the network of wireless mobile nodes with selforganizing, dynamic network connectivity without any pre-defined infrastructure for wireless communication. Error-less data broadcasting is the major role in MANET transmission. With the salient feature of dynamic topology and the distributed infrastructure, multipath routing is of great interests in MANETs. Multipath routing methods are dependable on adjacent nodes for finding the shortest path that several data packets are fallen to network traffic. Attention on the adjacent nodes can have the end-to-end delay while broadcasting the data packets into other nodes that finish up being fallen to congestion. It will also reduce network throughput and cause the network optimality problem. In this paper, we propose a new link-disjoint multipath routing method to solve the optimization problem in the real-time network environment. Hence, the proposed method is used to choose the shortest path from multiple paths in MANETs. Simulation results proved that the proposed method performs well in the dynamic network environment.INDEX TERMS MANET, multipath routing, shortest path, load balancing.

Mobile Ad Hoc Networks (MANET) are autonomous, infrastructure less and self-configuring networks. MANETs has gained lots of popularity due to on the fly deployment i.e. small network setup time and ability to provide communication in obstreperous terrains. Major challenges in MANETs include routing, energy efficiency, network topology control, security etc. Primary focus in this article is to provide method and algorithm to ensure significant energy savings using re-configurable directional antennas. Significant energy gains can be clinched using directional antenna. Key challenges while using directional antenna are to find destination location, antenna focusing, signal power and distance calculations. Re-configurable directional antenna can ensure significant energy gains if used intelligently. This article provides a brief insight into improved energy savings using re-configurable directional antennas and an associated algorithm Keywords: Directional Antennas; Energy Efficiency; Antenna Re-configuration; Mobile Ad hoc Networks; Genetic Algorithms I. INTRODUCTIONMobile ad hoc networks (MANET) are versatile kind of network and are able to work in numerous situations and places where provision of fixed infrastructure is not feasible. MANETs are amenable to topology change as the topology changes over time. The participating nodes are mobile and support unrestricted movement in a limited geographic area [1]. MANET works over wireless communication medium and wireless medium is susceptible tohigh interference and connection failure. Due to this the participating nodes should be able to heal themselves and reconstruct the network state. MANETs usually operates using mesh topology and a conventional mobile node uses Omni-directional antenna (which emanates isotopic radiations) for communication. Using these antennas mobile nodes cannot easily find the location and distance of the destination nodes and suffer huge energy losses. Reconfigurable directional antennas are panacea for these problems. These kinds of antennas are highly adaptive to topology change and provides other numerous advantages. Reconfigurable directional antennas (RDA) are able to reduce collisions in the communication and second major advantage is the antenna gain. The increased gain improves the transmission range of nodes and significantly reduces the number of hops required to reach the destination [5]. Reconfigurable antennas offer following explicit advantages over conventional directional antennas [9,14].
