MLRU (Minimum Advanced Medium Access Protocol Logical Resource Unit)

Last updated on 

The Minimum Advanced Medium Access Protocol Logical Resource Unit (MLRU) is a protocol used in wireless communication networks to allocate logical resources efficiently. MLRU is designed to work with medium access control (MAC) protocols in wireless networks and is used to allocate logical resources for data transmission. This protocol is used in wireless communication networks such as cellular networks, wireless LANs, and other wireless networks.

In wireless communication networks, the resources are limited and shared among different users. Therefore, the allocation of these resources is critical to ensure efficient network utilization. MLRU provides a mechanism to allocate these resources efficiently and fairly among different users. The MLRU protocol is designed to provide a fair allocation of resources based on the traffic demand and the available resources.

MLRU is a two-step process that involves resource allocation and admission control. In the resource allocation step, MLRU assigns logical resources to the users based on their traffic demand and the available resources. In the admission control step, MLRU determines whether a user can be admitted to the network based on the available resources.

Resource Allocation

The resource allocation step is performed periodically, and MLRU allocates the resources to the users based on the traffic demand and the available resources. MLRU considers the following parameters while allocating resources:

  1. Traffic demand: MLRU allocates the resources based on the traffic demand of the users. Users with higher traffic demand are allocated more resources than users with lower traffic demand.
  2. Resource availability: MLRU allocates the resources based on the availability of resources. If there are fewer resources available, MLRU allocates the resources to the users with higher priority.
  3. Priority level: MLRU allocates the resources based on the priority level of the users. Users with higher priority are allocated more resources than users with lower priority.
  4. Quality of Service (QoS) requirements: MLRU allocates the resources based on the QoS requirements of the users. Users with higher QoS requirements are allocated more resources than users with lower QoS requirements.
  5. User fairness: MLRU allocates the resources fairly among the users. Users are given an equal opportunity to access the resources, and no user is given preferential treatment.

Admission Control

The admission control step is performed when a new user requests access to the network. MLRU determines whether the new user can be admitted to the network based on the available resources. MLRU considers the following parameters while performing admission control:

  1. Available resources: MLRU determines whether the available resources are sufficient to accommodate the new user. If the available resources are not sufficient, MLRU rejects the admission request.
  2. QoS requirements: MLRU determines whether the QoS requirements of the new user can be met with the available resources. If the QoS requirements cannot be met, MLRU rejects the admission request.
  3. User priority: MLRU determines whether the new user has higher priority than the existing users. If the new user has higher priority, MLRU may admit the user at the expense of the existing users.
  4. Network congestion: MLRU determines whether admitting the new user will cause network congestion. If admitting the new user will cause network congestion, MLRU may reject the admission request.
  5. Fairness: MLRU determines whether admitting the new user will affect the fairness of resource allocation among the existing users. If admitting the new user will affect the fairness, MLRU may reject the admission request.

MLRU Implementation

MLRU is implemented as a software module in the MAC layer of the wireless network. The MLRU module interacts with the physical layer to obtain information about the available resources and the traffic demand. The MLRU module also interacts with the upper layers to obtain information about the QoS requirements and the user priority.

MLRU can be implemented using various algorithms, such as the Round Robin algorithm, which allocates the resources in a cyclic order among the users, and the Weighted Round Robin algorithm, which allocates the resources based on the user priority. Other algorithms, such as the Max-Min Fairness algorithm, can also be used to allocate the resources based on the user fairness.

MLRU can also be implemented using different scheduling techniques, such as time division multiple access (TDMA), frequency division multiple access (FDMA), and code division multiple access (CDMA). TDMA divides the time into fixed intervals, and each user is allocated a specific time slot to transmit data. FDMA divides the frequency band into different sub-bands, and each user is allocated a specific sub-band to transmit data. CDMA allows multiple users to transmit data on the same frequency band simultaneously using different codes.

MLRU can also be used in different types of wireless networks, such as cellular networks, wireless LANs, and wireless mesh networks. In cellular networks, MLRU is used to allocate the resources among the users in each cell. In wireless LANs, MLRU is used to allocate the resources among the users in the same access point. In wireless mesh networks, MLRU is used to allocate the resources among the users in different mesh nodes.

Conclusion

The Minimum Advanced Medium Access Protocol Logical Resource Unit (MLRU) is a protocol used in wireless communication networks to allocate logical resources efficiently. MLRU provides a fair allocation of resources based on the traffic demand, the available resources, the user priority, the QoS requirements, and the user fairness. MLRU is implemented as a software module in the MAC layer of the wireless network and can be used with different algorithms and scheduling techniques. MLRU is used in different types of wireless networks, such as cellular networks, wireless LANs, and wireless mesh networks, to allocate the resources among the users efficiently and fairly.
