The Full ESWAN Destination-Based Approach: Operations And Evaluation
In response to the growing need to support better than best-effort (BE) quality of service (QoS) in mobile ad-hoc and sensor networks, many QoS models have been proposed. SWAN independent QoS model is introduced to operate on wireless ad-hoc networks. As a cross layer QoS model, SWAN is flexible and may run over any routing protocol or Media Access Control (MAC) layers. SWAN provides some advantages over competitive models However, SWAN is vulnerable to problems related to mobility and false admission. The original SWAN model discusses the two problems as part of a dynamic regulation of real-time flows, and introduced two solutions, namely source and network-based regulation algorithms. This paper criticizes both regulation algorithms and show why destination-based algorithm selects real-time victim flows in a better way. Then we provide test results to analyze and evaluate the destination-based approach.
