A Tutorial on Cross-layer Optimization Wireless Network System Using TOPSIS Method

Wireless network system. Introduction: The availability and rising demand of ubiquitous connectivity has been one of the most revolutionary technological trends of the last ten years. Today, we anticipate being able can access these internet services at any time, from everywhere, for a variety of purposes, including checking email, using the phone, browsing the web, and a plethora of other uses, such as when travelling by car, subway, airline, or anywhere else. Although we still need to actively seek out connections today (by looking for a Wi-Fi hotspot nearby), the future will undoubtedly feature ubiquitous connectivity and Internet access. Central to this movement are wireless networks. A wireless network is any network that is not linked by cables and provides the user with the comfort and mobility they need. We may anticipate that dozens of various wireless technologies will be available to satisfy the demands, each with distinct performance requirements and each tailored for a particular task and environment, given the enormous variety of use cases and applications. Research signification: The densest wireless network deployments up until recently took place in campus-like settings, with the cell architecture being meticulously planned by professionals. The wireless environment is evolving quickly due to the increasing adoption of low-cost 802.11 equipment as well as other personal wireless devices (2.4 GHz cordless telephones, Bluetooth devices). There are two significant differences between dense installations of wireless networking hardware in locations like neighborhoods, shopping centers, and apartment buildings and campus-type deployments. First, numerous separate people or devices, each installing one or a small number of APs, result in complicated installations that are meticulously planned to enhance coverage and reduce cell overlap. The concentration of wireless sensor nodes and APs produced by this kind of haphazard, unplanned deployment is widely varied (and sometimes quite high). Methodology: Alternative: 1G, 2G, 3G, and 4G. Evaluation Preference: Multiplexing, Implementation, Services, Standards, Core Network. Results: from the result it is seen that Core Network is got the first rank where as is the Services is having the lowest rank. Conclusion: The value of the dataset for Wireless network system in TOPSIS method shows that it results in Core Network and top ranking.
