Essay / Mimo and Comp in LTE-advanced
CoMP is considered for LTE-Advanced as a way to improve the coverage area of high data rate communications, cell throughput for MTs and as a way to increase the system. flow under varying load conditions. CoMP is used to coordinate transmissions with multiple cells and to reduce interference from neighboring cells and thus reduce the power required to maintain a certain QoS. Say no to plagiarism.

They also studied the effect of system parameters (traffic intensity and network density) on energy efficiency performance. In Ismail and Zhuang, network cooperation for large- and small-scale traffic fluctuations was modeled and analyzed. In case of large-scale fluctuations, networks with overlapping coverage could alternately enable or disable their BSs based on long-term fluctuations in traffic load. On a small scale, each active BS can turn its wireless channels on and off based on short-term fluctuations in traffic load. WMNs are also growing rapidly and are expected to address the limitations of ad hoc networks, WLANs, WPANs and WMANs, as well as crucially improve their performance. WMNs are capable of providing a wide variety of wireless applications in daily, public and private life. Despite all the recent developments, there is still a lot of work to be done in the different layers of the WMN protocol. Due to the possibility of deploying WMNs over existing wireless technologies, some companies have already launched their rather pioneering WMN products to the market. Practical experience, however, shows that WMNs can and should be improved in several areas: Scalability Overall network performance metrics (throughput, end-to-end delay, and fairness) are not scalable based on the number of nodes or hops network. The problem can be alleviated somewhat by increasing the capacity of network nodes, for example by using multiple radios or channels in a node, or by using radios with higher communication speeds. These improvements will not completely resolve the issues, however: relative performance over the increased network capacity is not affected. The new MAC, routing and forwarding protocols will however. Self-organization and self-configuration This implies that all WMN protocols were fully distributive and collaborative, which is however not currently true. Security Current security procedures leave the WMN partially without protection against security attacks in different protocol layers. Network Integration WMNs are currently quite limited in their ability to integrate heterogeneous wireless networks, due to the problems of integrating multiple wireless interfaces and their corresponding gateway/bridge functions into the same WMN router. Software defined radios may be the answer to this problem.Keep in mind: This is just an example.Get a personalized article now from our expert writers.Get a custom essayPerformanceWMNs still lag behind networks wired in terms of throughput and delays. The most apparent reason for poor performance of WMNs (e.g. low throughput, high network latency) is primarily due to networks..
