Since LTE in unlicensed spectrum (LTE-U) was proposed by Qualcomm, it has drawn considerable interest because of its potential to increase the capacity of existing LTE networks by utilizing existing infrastructure in the unlicensed band. But, Wi-Fi technology, already operating in the unlicensed 5 GHz band, creates several potential challenges for managing the activities of these two different technologies...
Due to the dynamic nature of the Mobile Ad-hoc Network (MANET), routing in MANET becomes challenging especially when certain QoS requirements (like high data packet delivery ratio, low end to end delay, low routing overhead, and low energy consumption) are to be satisfied. Though a number of routing protocols have been proposed aiming to fulfill some of these QoS requirements but none of them can...
In wireless communication, low propagation delay and low power requirements of satellite are key requirements which makes low earth orbit (LEO) satellite preferable over others. Over the years a plenty of researches had been done in this field of satellite handover management, but the problem remains unsolved. One such method is the reservation of a few channels specifically for handover calls. One...
In wireless local area network (WLAN), mobility management becomes a sophisticated issue of research due to the limited coverage of the Access Points (AP). For the successful communication between the mobile nodes (MN), every node should be connected with an access point (AP) during their operating mode, irrespective of their mobility. When a MN travels into the coverage area of its current AP, no...
In wireless communication, handoff has become an important topic of research. A mobile station (MS) requires handoff when it travels out of the coverage area of its current access point (AP) and tries to associate with another AP. But handoff failure probability provides a serious barrier for such services to be made available to mobile platforms. Throughout the last few years plenty of research had...
In wireless & mobile communication the mobility management technique is an important issue of research. To fulfill the criteria of the all time connectivity, the mobile station (MS) should be connected with a base station (BS) during its operating mode, irrespective of its mobility. When a MS travels within the cell, no special technique is required to maintain its connectivity. But when a MS...
Connectivity control technique in next generation wireless system is a burning issue of research. Throughout the last few years plenty of researches had been done to obliterate the connection failure problem by implementing several channel allocation schemes. In this paper, we propose a new scheme of connectivity control by implementing some Short Coverage Antennas (SCA) in the cell. If the channels...
In wireless communication, low earth orbit (LEO) satellite has become a popular name, due to their low propagation delay and low power requirements. Throughout the last few years a plenty of researches had been done to improve the LEO satellite communication by implementing several channel allocation techniques. In this paper we are going to propose a new adaptive channel allocation scheme for efficient...
