Rate Allocation and Buffer Management for Proportional Service Differentiation in Location-Aided Ad Hoc Networks [chapter]

Sivapathalingham Sivavakeesar, George Pavlou
2005 Lecture Notes in Computer Science  
Given that applications and services for evolving mobile ad hoc networks (MANETs) have diverse quality of service requirements in a similar fashion to fixed networks, this paper proposes a proportional  ...  This model is highly scalable and simple to adopt in MANETs because it does not require explicit admission control or maintenance of state information in any intermediate node.  ...  In addition, absolute differentiation requires sophisticated admission control and resource reservation mechanisms, which are difficult to achieve in highly dynamic ad hoc networks.  ...
