Write 5 pages with APA style on Analysis to Prove Reservation-based Ad Hoc Wireless Systems is Better in Performance. In contrast, soft and non-real-time guarantees are provided for communication resources. Notably, the reservation-based ad hoc wireless systems approach achieves more efficient utilization of the resources whereby network bandwidth is reserved for hard real-time events whereas no resource reservation is made for soft and non-real-time events. As there is a risk of soft real-time tasks to become overloaded, we additionally define reservations for soft real-time tasks obtained from two sources. Firstly, resources are obtained from those that were not reserved by hard real-time tasks. The second source is a bounded overlapping region with the resources assigned to hard real-time tasks. As a result, some soft real-time events will miss their deadlines when hard real-time events use this region but the probability of meeting their deadlines will increase.
But as compared to nonreservation based ad hoc wireless systems no such resource management at such level can be possible. Here in resources management, it will be preferred to establish a reservation-based ad hoc wireless systems approach.
The highly dynamic nature of ad hoc networks makes the coordination of nodes competing for resources an essential issue. Therefore, task managers are introduced to control the allocation of resources according to both the QoS demands and the criticality of the tasks. There is a task manager per node. In reservation-based ad hoc wireless systems, the resource management CF provides important support for the task managers in terms of resource awareness, resource reservation, and resource reallocation. Resources for hard and soft real-time classes are statically reserved according to the defined tasks. For instance, when subscribing to a video-on-demand service supported by task y, resources are allocated if no other video sessions have been set up or enough resources are left for the new session. The resource requirements of announced and subscribed event types are obtained from a task information repository. As a result, resource allocation is granted for publishing and consuming events in the case of hard and soft real-time tasks. For that purpose, the task manager is in charge of requesting the appropriate resource managers to perform both the admission control tests and the reservation of resources when the test is successful.
