“…Secondly, separate backhaul is not required for RSs as they can utilize the existing GBS backhaul in urban areas where installation costs are high and even most of the time, options are not available. The RSs can be installed and removed easily to address coverage holes of cellular systems increasing their coverage and capacity as described by WiMAX (IEEE 802.16 j and IEEE 802.16 m) and LTE-A [10] standards. In emerging cellular networks, the RSs are aimed to increase the coverage density to one million MSs in a square kilometer area.…”

One of the best evolution in technology breakthroughs is the Unmanned Aerial Vehicle (UAV). This aerial system is able to perform the mission in an agile environment and can reach the hard areas to perform the tasks autonomously. UAVs can be used in post-disaster situations to estimate damages, to monitor and to respond to the victims. The Ground Control Station can also provide emergency messages and ad-hoc communication to the Mobile Users of the disaster-stricken community using this network. A wireless network can also extend its communication range using UAV as a relay. Major requirements from such networks are robustness, scalability, energy efficiency and reliability. In general, UAVs are easy to deploy, have Line of Sight options and are flexible in nature. However, their 3D mobility, energy constraints, and deployment environment introduce many challenges. This paper provides a discussion of basic UAV based multi-hop relay network architecture and analyses their benefits, applications, and tradeoffs. Key design considerations and challenges are investigated finding fundamental issues and potential research directions to exploit them. Finally, analytical tools and frameworks for performance optimizations are presented.

In wireless networks, the handover in the network layer (L3) is usually initiated after the handover in the link layer (L2) is complete, so the total handover delay is equal to the sum of the L2 handover delay and the L3 handover delay. In order to reduce the total handover delay, this paper studies the correlations between the L2 messages and L3 ones, and proposes a cross-layering handover scheme. The main idea behind this scheme is to effectively combine the related messages in L2 and L3 and achieve the L3 handover with the L2 messages in order to minimize the effect of the L3 handover delay on the total handover delay. The performance of this scheme is evaluated, and the results show that this scheme effectively reduces the total handover delay.
