Further, we question the need for separate MAC and network addresses and show how our spatially reused locally unique node address could be used in both contexts, leading to greater energy efficiency.
In this paper, we propose a new MAC protocol, called proxy relay-enabled MAC (PR-MAC), to improve the capacity of multi-rate WLANs.
Simulation results indicate that COM-MAC can achieve increased network throughput at the cost of a small control and energy overhead.
Simulation results reveal that our NCAC-MAC can improve the network performance under general circumstances.
Also, the evaluation of the impact of switch backplane size shows that given a certain set of network modules, an optimal switch backplane size exists, which achieves the lowest hardware cost.
To increase network throughput, we propose an optimal grouping strategy for efficient helper node selection, and devise a greedy algorithm for MAC protocol refinement.
The simulation results have confirmed that the proposed network access mechanism can achieve excellent performance owing to the lifetime and energy efficiency-based relay path selection algorithm and the MAC address forwarding tables mechanism.
Simulation results show that the proposed MAC protocol can provide reliability guarantees for obtaining high network throughput while reducing the interference to primary systems.

What are the advantages and disadvantages of a clap-based switch?5 answersA clap-based switch has several advantages. Firstly, it allows for the conversion of sound energy into electrical energy, making it a convenient way to control electric circuits. Additionally, it offers a hands-free and easy-to-use method of turning devices on or off, such as fans, lights, and TVs, simply by clapping. Another advantage is that it can be used with various appliances due to its simple structure and low manufacturing cost. On the other hand, there are also some disadvantages to consider. Clap-based switches may be sensitive to background noise, leading to unintended activations or deactivations. Furthermore, they may not be suitable for environments with high levels of ambient noise, as this can interfere with their functionality.

How mac is designed in 802.11p?5 answersThe MAC layer in the IEEE 802.11p standard is designed to address the challenges of vehicular networks, such as fast changing topologies, short connection lifetimes, and high node density. The MAC protocol in 802.11p grants all nodes equal opportunity to acquire the channel, which can lead to lower bit-rate nodes occupying the channel for a fair amount of time, affecting the overall network performance. To improve network throughput and decrease the probability of collisions, a new MAC protocol is proposed that guarantees nodes with acquired channel a firm priority over other nodes for a fixed amount of time, using the TXOP concept. Additionally, the MAC protocol sets the Contention Window (CW) width wider than the standard and modulates the continuous transmitting threshold value based on channel acquired time, further enhancing network performance.
How to switch language in macbook pro laptop keyboard?5 answersTo switch languages on a MacBook Pro laptop keyboard, you can use different methods. One method is to use a switchable language family keyboard, which includes a control unit with column and row I/O ports, a key trigger circuit, and a memory cell to store key codes. Another method is to use a combined virtual keyboard that allows simultaneous access to alphabet characters of different languages, with the characters partially overlapped when combined. A multi-language keyboard with keys, chambers, characters, and light sources can also be used for language switching. Additionally, multiple legends implemented by illuminable characters integrated into the keys, hinged templates, or controlled liquid crystal display legends can be used to represent characters of different languages. Finally, an operating system can provide facilities for switching keyboard configurations and code pages, allowing users to change keyboard languages without interrupting application execution.
What is different between router and switch?2 answersA router and a switch are both network devices used for forwarding network traffic, but they have some key differences. A router operates at the network layer (Layer 3) of the OSI model and uses dynamic IP routing protocols or static/manual configuration to learn about other networks and paths to destination networks. It performs control plane operations and data forwarding plane operations, with the routing engine handling control plane operations and the forwarding engine handling data forwarding plane operations. On the other hand, a switch operates at the data link layer (Layer 2) of the OSI model and forwards network traffic based on MAC addresses. It does not perform routing functions like a router. Additionally, a switch can be either centralized or distributed in terms of its architecture.
