Mobile communication networks have become an integral part of our society, significantly enhancing communication capabilities. Mobile ad hoc networks (MANETs) extend this capability to any time/anywhere communication, providing connectivity without the need of an underlying infrastructure. The new coming realm of mobile ad hoc networks is first investigated, focusing on research problems related to the design and development of routing protocols, both from a formal and technical point of view. Then link stability in a high mobility environment is examined, and a route discovery mechanism is analyzed, together with a practical implementation of a routing protocol in ad hoc multi-rate environments which privileges link stability instead of traditional speed and minimum distance approaches.

Technical advancements in wireless technology and portable devices leading to new features in wireless communication networks, mobile ad hoc networks (MANETs) are a kind of them. MANETs are, containing autonomous mobile nodes (nodes with special abilities) a class of multihop wireless networks where two distant nodes can communicate with each other without a centralized administration or an underlying network infrastructure. Networks having such features find applications like where there is a need for an instantaneous temporary network to handle emergency situations. On the other hand, being dynamic networks with time to timevarying topologies MANETs are placing the challenges in routing the data packets in the network. This paper presents an extensive simulation work done on the most prominent ondemand routing protocol i.e., ad hoc on demand distance vector routing protocol (AODV) is for a set of performance evaluation parameters by varying a set of various network parameters.

Mobile ad hoc network (MANET) attracted various researchers in the emerging communication networks without having any centralized structure. In this network, mobile nodes moves in their own wish creating a dynamic topology. Routing is a cumbersome task with this dynamic topology from time to time change in connection pattern. DYMO is emerged as challenging protocol in MANET but works on static configuration parameters such as Hello messages. The mobile device updates the connectivity of their neighbours by sending Hello messages at frequent intervals irrespective of the network scope (terrain) and network elements(number of nodes). As the mobile nodes are battery equipped devices, lot of energy is consumed with these messages. Energy efficient mechanisms are necessary in this type of networks. In this work, DYMOHBFLWTN mechanism is proposed to set the Hello parameter dynamically in DYMO considering network terrain and number of nodes utilizing fuzzy principles. Experiments are conducted on Qualnet 7.0 simulator to evaluate mechanisms - DYMOHBFLWTN and DYMO. The proposed DYMOHBFLWTN mechanism provides better results compared to existing DYMO.

In the future, communication devices, communication-capable devices or sensors and home electronic appliances will have the capability to form various MANETs, and interoperate with the global communication networks. These MANETs play an important role in supporting various visions toward the creation of a world of ubiquitous computing where computation is integrated into the environment, rather than having computers that are distinct objects. One of the goals of ubiquitous computing is to enable devices to sense changes in their respective surroundings and to automatically adapt and act on these changes based on user needs and preferences. With ubiquitous computing, people can move around and interact with computers, devices and home appliances more naturally than they currently do.

Unmanned aerial vehicles (UAVs) have the potential of creating an ad hoc communication network in the air. Most UAVs used in communication networks are equipped with wireless transceivers using omnidirectional antennas. In this paper, we consider a collection of UAVs that communicate through wireless links as a mobile ad-hoc network using directional antennas. The network design goal is to maximize the throughput and minimize the end-to-end delay. In this respect, we propose a new medium access control protocol for a network of UAVs with directional antennas. We analyze the communication channel between the UAVs and the effect of aircraft attitude on the network performance. Using the optimized network engineering tool (OPNET), we compare our protocol with the IEEE 802.11 protocol for omnidirectional antennas. The simulation results show performance improvement in end-to-end delay as well as throughput.
